Not only do people except a reliable and fast connectivity in their offices, but also at their favorite coffee shops and grocery stores. Setting up the network to provide such connectivity is not everybody’s cup of tea; setting these networks is complex and time consuming and most of the times small business with little to no in-house expertise, end up hiring third party companies to do such tasks. Now, with the introduction of<SPAN><A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/products/switches/catalyst-2960-l-series-switches/index.html" target="_blank">Catalyst 2960-L Smart Managed switches</A>&nbsp;</SPAN>small businesses would no longer need to worry about setting up their access network.</P> <P><STRONG>Bringing years of expertise to masses</STRONG></P> <P>The unparalleled knowledge and expertise of Cisco engineering and sales teamshas been synthesized and provided to the customers in a simple, and easy-to-consume Day 0 Wizard required to configure their networks. We broke down the boundaries between a Switch and an Access Point by allowing users to configure not only their Catalyst 2960-L series switches, but also <SPAN><A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/solutions/enterprise-networks/mobility-express/index.html" target="_blank">Mobility Express</A>&nbsp;</SPAN>Access points from the same Web UI thus allowing small business a single pane of glass to configure everything they need to provide connectivity to their customers.</P> <P><STRONG>Set up your small office in just three clicks!</STRONG></P> <P>Using day 0 wizard, powered by <SPAN><A href="http://nomesintegrated.com/?page=http://cisco.com/go/ccp-catalyst" target="_blank">Cisco Configuration Professional for Catalyst (CCPC)</A>&nbsp;</SPAN>is simple and quick! Power on the switch, connect the Access Point to any port and press the mode button on the switch, and the Day 0 Wizard is ready for you to configure.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" style="width: 999px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/24229i9B85FE2638AAB82F/image-size/large?v=1.0&amp;px=999" alt="C2960L-Day0-Pic01.JPG" title="C2960L-Day0-Pic01.JPG" /></span></P> <P>Once you enter the wizard, there are just three steps that a user needs to follow in order to complete their network’s configuration. The wizard provides for context based helps and tips providing detailed overview of what that particular field really means and how the user should go about completing them. First, it asks for some basic configuration required to identify and connect to the devices followed by interface configuration wherein the user provides their network segregation intent, and enabling SVIs and DHCP Services over these network segments has never been easier.<BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" style="width: 999px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/24230i696A4C34C448FFB0/image-size/large?v=1.0&amp;px=999" alt="C2960L-Day0-Pic02a.JPG" title="C2960L-Day0-Pic02a.JPG" /></span></P> <P>Lastly, the wizard would ask for Wireless specific details which it could not derive from the previous two steps such as the Country to determine RF parameters, SSID and the security mechanism to authenticate clients over.<BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" style="width: 999px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/24231iA796CD4A76E51595/image-size/large?v=1.0&amp;px=999" alt="C2960L-Day0-Pic04.JPG" title="C2960L-Day0-Pic04.JPG" /></span></P> <P>Once a user finishes these three steps, they have successfully set up their entire access layer in one go Cisco recommended best practices enabled out of the box. So, all the people, who could not get their SSID to work because they either did not allow proper VLANs on switchport or did not set the correct native VLAN for AP management network, worry no more, Cisco is here for you! Once the network is set up, CCPC also provides a comprehensive dashboard to allow customers to monitor their device from a single pane of glass.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" style="width: 999px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/24228iB57613A5646E4B08/image-size/large?v=1.0&amp;px=999" alt="Screen Shot 2018-11-15 at 3.32.47 PM.png" title="Screen Shot 2018-11-15 at 3.32.47 PM.png" /></span><STRONG>Conclusion</STRONG></P> <P>&nbsp;</P> <P>Cisco has been a leader in enterprise networking for decades and now brings the same reliability and enterprise quality to SMB with the introduction of new Catalyst 2960-L Smart Managed switches. Together with Cisco Catalyst and Mobility Express, customers do not need to be IT experts to set up their network with ease and quickness.</P> <P>&nbsp;</P> <P><STRONG>So why settle for “good enough” when you can have the best– Cisco!</STRONG></P> Fri, 16 Nov 2018 00:18:25 GMT https://community.cisco.com/t5/network-architecture-blogs/catalyst-2960-l-smart-managed-switch-enabling-networking-for/ba-p/3747764 jayshar 2018-11-16T00:18:25Z Get notified, analyze, detect, and remediate the fault – all in one fell swoop! https://community.cisco.com/t5/network-architecture-blogs/get-notified-analyze-detect-and-remediate-the-fault-all-in-one/ba-p/3746646 <P>The more I learn about the applications Cisco partners are building using the DNA Center’s open APIs, the more I am impressed by the creativity by which they are using these APIs. Their solutions are helping network operations by removing the guesswork and manual steps traditionally employed to find and fix network issues.</P> <P>One shining example of such an application is Micro Focus’s IT Operations Management (ITOM) solution. The complete solution consists of six separate management applications that encompass IT service, hybrid cloud, and data center. The two applications, out of the six, that they have integrated with DNA Center are Network Operations Management (NOM) and Operations Bridge. Whereas Networks Operations Management (NOM) focuses on monitoring of networks, Operations Bridge acts on the output from monitoring, analyzes service impact of an infrastructure issue, and takes remedial actions.</P> <P>&nbsp;</P> <H1>Bidirectional integration with DNA Center</H1> <P>The two applications tie in extremely tightly with DNA Center. Network Operations Management (NOM) uses DNA Center’s integration APIs to retrieve network data from DNA Center. This data includes events, network topology, and incident trends on both wired and wireless networks. NOM goes on to assimilate this data, add compliance information and send it on to Operations Bridge, Operations Bridge consumes the data, adds application health statistics, and presents it in a single-pane-of-glass dashboard for operators.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-center" style="width: 973px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/24108i309FB07A8D40F2B3/image-size/large?v=1.0&amp;px=999" alt="Microfocus.png" title="Microfocus.png" /></span></P> <P>As part of its analysis, NOM combines the data it receives from DNA Center with data it gathers from other sources, and passes the data (events, metrics and topology) to Operations Bridge. Operations Bridge then creates a comprehensive view of the complete IT operations. Users can now detect a problem, if any, and by event correlation, identify the root cause and remediate the problem using operations orchestration through its interface with DNA Center.</P> <P>“DNA Center as an open platform is very significant for our customers and they are quite excited that Cisco DNA now provides REST APIs for automation.”, says Tapan Shah, Product Manager of Network Operations Management product at Micro Focus, “We at Micro Focus consume these APIs to drive monitoring and provisioning use-cases. We integrate with DNA Center in a bidirectional manner. We get network events from it, determine the impact to applications, if any, and if so, isolate the network fault, and then use DNA Center provisioning APIs to remediate the fault.”</P> <P>Watch Tapan demonstrate the solution.</P> <P><LI-VIDEO vid="https://youtu.be/QHJEehDBkfA" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/QHJEehDBkfA/hqdefault.jpg" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <H1>Conclusion</H1> <P>With the DNA Center open platform, Cisco has opened many opportunities for independent software vendors, such as Micro Focus, to enrich their own offerings with the native functions and the network data collected and insights generated by the DNA Center. Partner written applications can not only programmatically access telemetry data but all its native automation and assurance capabilities as well, and deliver solutions that solve business needs simply, efficiently, and effectively.</P> <P>Read this <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/dam/en/us/products/collateral/cloud-systems-management/dna-center/nb-09-idc-open-platform-analyst-rpt-ctp-en.pdf" target="_blank">white paper from IDC</A> to see how you can leverage network as an open platform and create new revenue opportunities.</P> <P><A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/partners/DNAC0008/" target="_blank">Discover this solution</A> and others from our <A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/" target="_blank">DNA Center open platform partners</A> and see how they are redefining the future of networking.</P> <P>&nbsp;</P> <H1>Find out more</H1> <P>Learn DNA Center APIs: <A href="http://nomesintegrated.com/?page=https://developer.cisco.com/dnacenter/" target="_blank">https://developer.cisco.com/dnacenter/</A></P> <P>See how intent-based networking can spark business innovation: <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html" target="_blank">https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html</A></P> <P><SPAN>Read the Cisco Focus Magazine special issue on Intent-Based Networking: </SPAN><A href="http://nomesintegrated.com/?page=https://newsroom.cisco.com/focus/2018/jun/intent-based-networking" target="_blank">https://newsroom.cisco.com/focus/2018/jun/intent-based-networking</A></P> <P>&nbsp;</P> Wed, 14 Nov 2018 18:32:41 GMT https://community.cisco.com/t5/network-architecture-blogs/get-notified-analyze-detect-and-remediate-the-fault-all-in-one/ba-p/3746646 vbharga 2018-11-14T18:32:41Z Cisco Catalyst 9200 with SD-Access – let the innovations continue! https://community.cisco.com/t5/network-architecture-blogs/cisco-catalyst-9200-with-sd-access-let-the-innovations-continue/ba-p/3746161 <P>The Catalyst 9000 family of switches is at the heart of Cisco’s Network Intuitive strategy.&nbsp; The success of Catalyst 9000 Series Switches is inspiring!

One of the most common examples of silos we see in organizations is their network and their IT service management. These technology islands depend on often times less-than-reliable “human middleware” for communication between them – with predictable results. For example, if a network issue needs to be resolved, someone has to create a ticket in the IT system, collect debug data from the network, if available, and add this data to the ticket. Once the resolution is found, someone needs to perform the actions in the network and then close the ticket. These manual processes slow down debugging and resolution of network issues and with insufficient information make it error prone.</P> <P>&nbsp;</P> <H1>Automation to the rescue</H1> <P>If you are tired of synchronizing data between these silos manually and want a better way to manage, then you should really look at the new application that Logicalis has created for its customers that automates these processes. In this application, Logicalis uses <A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">Cisco DNA Center open platform</A> capabilities that expose REST based APIs to external applications. Using these APIs, the application obtains network data regarding devices, their location, health information and firmware versions, and other data relating to telemetry from DNA Center. Moreover, the application also uses DNA Center’s native automation and assurance capabilities.<span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 999px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/22564iA01F66D3A6D1F965/image-size/large?v=1.0&amp;px=999" alt="Logicalis.png" title="Logicalis.png" /></span></P> <P>&nbsp;</P> <P>&nbsp;</P> <P>&nbsp;</P> <P>&nbsp;</P> <P>The application receives notifications if DNA Center detects anything amiss in the network. Then using the DNA Center APIs, it is able to obtain all the contextual data related to the issue. This data could be invaluable in finding a resolution. The application then creates a ticket in IT service management system and adds all collected data to it.</P> <P>In the case where a user reports an error and creates a ticket in the IT service system, the application is still able to use DNA Center APIs to get all the data associated with the user and the devices they are using and add it to the user-generated ticket. Thus, no matter how the problem is first reported, there is always contextual data that can ease any troubleshooting and eventual resolution. And all this without humans shuffling data between the IT systems and network management!</P> <P>“An open platform is very important to us and our customers as it allows integration between multiple systems to meet business needs”, says Renae Johnson, Sr Alliance for Cisco, at Logicalis. “We leverage DNA Center’s assurance component to streamline ITSM processes such as incident management and problem management, by enriching workflows with data.”</P> <P>Watch as Cory Kramer, Solutions Architect at Logicalis, shows the two use cases by mediating among and closing the gap between DNA Center and ServiceNow, the ITSM system.</P> <P><LI-VIDEO vid="https://www.youtube.com/watch?v=_6JCUc3zYlk" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/_6JCUc3zYlk/hqdefault.jpg" external="url"></LI-VIDEO></P> <H1>&nbsp;</H1> <H1>Conclusion</H1> <P>With the DNA Center open platform, Cisco has opened the enterprise network for innovation.

When IBM takes on a project, you can bet that it will be global in its proportions. But called upon to revamp the networking of 250 branch offices of a multinational company, even IBM knew that it had a mammoth task on its hands. A task that could easily have taken hundreds of engineers doing lots of manual work that could be time-consuming and error prone. However, drawing on their previous experiences, IBM chose to utilize automation in order to save money and time.</P> <P>The first task was to set up an SD-WAN solution linking each branch with the main campus. Each of the branches would have network connectivity through both an internet and an MPLS connection. The second task was to deploy virtualized network services in each of the branches. Servers within each branch would run virtualized routers and firewalls&nbsp;that would control access&nbsp;between the WAN and&nbsp;the branch LAN.&nbsp; Almost all branches would have redundant systems, which meant setting-up as many as 450 such servers.</P> <P>&nbsp;</P> <H1>Go global with network automation</H1> <P>Faced with this challenge, IBM turned to Cisco’s Digital Network Architecture (DNA) and DNA Center. They chose Cisco’s <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/products/routers/5000-series-enterprise-network-compute-system/index.html" target="_blank">Enterprise Network Compute System</A> (ENCS) as their appliance. ENCS is a compute appliance family designed for a virtualized, <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/solutions/enterprise-networks/sd-branch/index.html" target="_blank">Software-Defined Branch</A> (SD-Branch) network architecture.<BR /><span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 250px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/21705i185739CB25FCA6BB/image-size/medium?v=1.0&amp;px=400" alt="IBM.png" title="IBM.png" /></span></P> <P>&nbsp;</P> <P>&nbsp;</P> <P>To solve the deployment problems, IBM first defined a provisioning template within DNA Center. Using <A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">DNA Center’s open APIs</A>, they wrote a custom Python script to retrieve this template and clone it across branches. The script then customizes each instance with its unique set of IP addresses, VLAN structure, etc. It also&nbsp;creates all the virtual network functions (VNFs) including virtual ISR with MPLS and internet connections, and virtual ASA, and chains them all together within ENCS.</P> <P>The script accomplishes all of this programmatically, dramatically reducing deployment time while also reducing the risk of minor differences between sites that can cause problems later.</P> <P>“The challenge before us was to deploy virtualized networking services on 250 sites using 450 appliances for a global customer,” said Markus Voegele, Network Architect at IBM, “It was clear that the only way we were going to be able to do this was to use automation. We found that Cisco DNA Center had the native capability to deploy and configure this set up, and with its support for open APIs, we were able to control this deployment through an application we wrote for the purpose. With simple Python scripts, we were able to deploy VLANs, virtual routers, virtual firewalls within ENCS servers at the sites, and link these together to form a service chain. Deploying and provisioning new sites, for us, is now as easy as choosing an option on a menu.”</P> <P>Watch Markus demonstrate the solution.</P> <P><LI-VIDEO vid="https://youtu.be/0Gd3TNhIC5M" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/0Gd3TNhIC5M/hqdefault.jpg" external="url"></LI-VIDEO></P> <H1>&nbsp;</H1> <H1>Conclusion</H1> <P>With its application, IBM shows how easy it can be to accomplish tasks on a global scale, which could easily take several months to complete manually. They have very effectively leveraged the capabilities of DNA Center and its open APIs and combined them with network virtualization. They have fully automated a process that is typically very expensive, time consuming, and challenging to implement.</P> <P>Read this <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/dam/en/us/products/collateral/cloud-systems-management/dna-center/nb-09-idc-open-platform-analyst-rpt-ctp-en.pdf" target="_blank">white paper from IDC</A> to see how you can leverage network as an open platform and create new revenue opportunities.</P> <P><A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/partners/DNAC0012/" target="_blank">Discover this solution</A> and others from our <A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/" target="_blank">DNA Center open platform partners</A> and see how they are redefining the future of networking.</P> <H1>&nbsp;</H1> <H1>Find out more</H1> <P>Learn DNA Center APIs: <A href="http://nomesintegrated.com/?page=https://developer.cisco.com/dnacenter/" target="_blank">https://developer.cisco.com/dnacenter/</A></P> <P>See how intent-based networking can spark business innovation: <A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html" target="_blank">https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html</A></P> <P><SPAN>Read the Cisco Focus Magazine special issue on Intent-Based Networking: </SPAN><A href="http://nomesintegrated.com/?page=https://newsroom.cisco.com/focus/2018/jun/intent-based-networking" target="_blank">https://newsroom.cisco.com/focus/2018/jun/intent-based-networking</A></P> Wed, 31 Oct 2018 20:29:30 GMT https://community.cisco.com/t5/network-architecture-blogs/when-global-site-deployment-is-as-easy-as-choosing-an-option-on/ba-p/3736844 vbharga 2018-10-31T20:29:30Z 2960-X IOS version https://community.cisco.com/t5/network-architecture-blogs/2960-x-ios-version/ba-p/3736577 <P>Which IOS version for the SW 2960 X 12.2 (XX)SE(X) will support the Track command</P> <P>because I have 2960-X with IOS version 12.2(55)SE7 but not supporting the Track command that I want to use it with The IP SAL</P> Wed, 31 Oct 2018 15:24:01 GMT https://community.cisco.com/t5/network-architecture-blogs/2960-x-ios-version/ba-p/3736577 ahmedabu_klam79@yahoo.com 2018-10-31T15:24:01Z Layer 2 Redundancy https://community.cisco.com/t5/network-architecture-blogs/layer-2-redundancy/ba-p/3736472 <H1>How to create a Layer 2 Redundancy for 2-default gateway, and how to enforce the SW-2960 when one of the SWs fail-over to go to the secondary default-gateway&nbsp; &nbsp; </H1> Wed, 31 Oct 2018 14:01:26 GMT https://community.cisco.com/t5/network-architecture-blogs/layer-2-redundancy/ba-p/3736472 ahmedabu_klam79@yahoo.com 2018-10-31T14:01:26Z Transparent Subnet Gateways Using Proxy ARP https://community.cisco.com/t5/network-architecture-blogs/transparent-subnet-gateways-using-proxy-arp/ba-p/3735561 <DIV style="font-family: Cambria, Georgia, serif; font-size: 12pt; color: #000000;">This is my first blog on the Cisco portal and my not a native English speaker.

However, to a lot of us network engineers, it feels like writing such programs can be hard to do. Thinking that it&nbsp;would&nbsp;need a lot of time and skill, we consider programming suitable only for large and complex applications. We even believe that&nbsp;programming should be best left&nbsp;for professional developers. To learn how other engineers are approaching the network programmability trend , I headed over to a group of Cisco partners who brought their solutions to the recent Cisco Live.</P> <P>Among the innovative use cases on demonstration there, Conscia’s reporting application struck me as a representative of a new class of applications that are purposeful, focused, and custom built to solve a specific problem.</P> <P>&nbsp;</P> <H1>Monitoring switch port status</H1> <P>In order to optimize usage, Conscia’s application focuses on monitoring the status of ports in various access switches in their customers’ networks.</P> <P>&nbsp;</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 253px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/21112i3D4C0C851A467BCD/image-size/medium?v=1.0&amp;px=400" alt="Conscia.png" title="Conscia.png" /></span>The application automates what can be a tedious time consuming task. After all, a person would need to inventory all the access switches in the network, log into each switch, and run CLI commands to check on the ports. Moreover, they would need to do this repeatedly and plot the results to determine the usage variance over time.</P> <P>Conscia’s application begins by using <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">DNA Center’s open APIs</A></SPAN> to map out the location of all the switches. From a high-level visual summary of switches, an operator can drill down into switches at each location, and then to an individual switch. The script can automatically log on to each switch, collect port status, and save the status into a spreadsheet. A technician could use the data collected in this&nbsp;spreadsheet to perform maintenance on the switches such as removing cabling from unused ports and getting them ready for new connections. The script can even be set to run the audit every 30 minutes to get a true picture over time.</P> <P>By having this insight into the availability of resources, Conscia’s customers can maximize their port usage and optimize their purchase of new switches.</P> <P>“At Conscia, we use the newest technologies to provide the best solutions to our customers in data center, mobility, security, and cloud”, says Henrik Boye, Director of Sales at Conscia. Adds Thomas Christensen, System Engineer at Conscia, “We see a big value in DNA Center open platform as it gives us the APIs that we can use to develop custom functions or applications that increase the usefulness of DNA Center. For us, it means that we can easily do small custom applications or integrate with ITSM systems such as ServiceNow and others”.</P> <P>Watch Henrik and Thomas demonstrate this solution.</P> <P><LI-VIDEO vid="https://www.youtube.com/watch?v=PK_0yX4QBgo" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/PK_0yX4QBgo/hqdefault.jpg" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <H1>Conclusion</H1> <P>With all its operational telemetry data, the network provides a rich information base ripe for analysis.

As the performance of the network as a whole depends on its weakest link, it is essential to ensure that each device is fully optimized, and running the latest “golden” version of software. However, having every network device run up-to-date version of software to achieve overall optimized performance is rarely if ever achieved, because image changes across all the devices is a never-ending and very time-consuming stream of tasks, and there is usually not enough time and people.</P> <P>&nbsp;</P> <H1>And fixing issues almost without manual intervention</H1> <P>Accenture has created an application that utilizes APIs made available by Cisco’s <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">DNA Center open platform</A></SPAN> to make ITSM ticket based image management request and resolution an automated process.

Accenture is highlighting image management in their demo but clearly, they can extend this automation to several different oft-repeated tasks. Automation saves time and money.</P> <P>In the bigger picture, Accenture is demonstrating a trend towards automation that DNA Center open platform makes possible. Its communication link to ServiceNow automates the ticket process from its opening to close. The solution requires minimal human intervention.</P> <P>ITSM ticket management automation via DNA Center open platform, when viewed as a solutions architecture, enables a wide variety of task identification and resolution to be machine driven. Accenture predicts that eventually machine driven operations will result in time savings of up to 90%. Charles Nebolsky says, “We are very excited about the DNA Center and its ability to dramatically augment how people work with technology. It is a mass multiplier in how they service clients and make technology more adaptable to what is going on in the world of cloud and digital.

There’s got to be a better way to identify trouble spots in the network. With the network playing an increasingly important role in our businesses and our lives and with new technologies becoming mainstream and indispensable, verifying that the network is performing as designed is critical.</P> <P>Having experienced this troubleshooting agony first-hand during my days as a developer, I was keen to see advances in this area and went to see the LiveAction booth at the recent Cisco Live. I learned how LiveAction’s LiveNX application makes&nbsp;diagnose and fix process simple by their powerful visualization tools that complement Cisco DNA Center’s native assurance capabilities.</P> <H1>&nbsp;</H1> <H1>You can’t troubleshoot what you can’t see</H1> <P>DNA Center collects extensive amount of telemetry data from the enterprise network. Sources of this data include network devices such as wired and wireless clients, wireless access points, routers, switches, and wireless LAN controllers, applications, as well as other contextual sources like LDAP, DNS, DHCP, AAA, CMX, IPAM, etc. In addition to collecting and performing its own comprehensive analysis, DNA Center also makes it available via <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">open APIs</A></SPAN> to external applications such as LiveNX. The following diagram illustrates this integration.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" style="width: 973px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/20030i4C11F715D1FA528C/image-size/large?v=1.0&amp;px=999" alt="LiveAction.png" title="LiveAction.png" /></span></P> <P>“Having an open platform like DNA Center is very important to us and our customers”, says John Smith, CTO and Founder, LiveAction, “The data that we get is at the heart of all our visualizations and analytics. So having access to all that data through open APIs is very critical to us. By integrating with DNA Center, we can benefit from its telemetry and insights, and are able to bring it up on our dashboards. This enables our customers to understand what is happening in the network and be able to troubleshoot and resolve their problems.”</P> <P>LiveNX uses these APIs to retrieve network data and adds to the native analysis performed by DNA Center. You gain from the seamless manner in which LiveNX interacts with DNA Center and the value-add it provides that can help you better understand network traffic to identify trouble spots. By its close integration with DNA Center, LiveNX allows you to cross-launch DNA Center’s troubleshooting and remediation capabilities directly from its own dashboard. LiveNX has built-in support for many Cisco technologies such as SD-WAN, SD-Access, and Meraki. With its visualization and 3<SUP>rd</SUP> party device support abilities, LiveNX can help during your during pre-deployment assessment, the deployment process itself, and later during operations.</P> <P>Watch John demonstrate the solution.</P> <P><LI-VIDEO vid="https://youtu.be/8sU7a2Qb66w" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/8sU7a2Qb66w/hqdefault.jpg" external="url"></LI-VIDEO></P> <H1>&nbsp;</H1> <H1>Conclusion</H1> <P>With the DNA Center open platform, Cisco has opened the enterprise network for innovation.

In the past, QoS traffic classification worked well by following these best practices. But being static, these rules do not handle customizations well or adjust dynamically to changing conditions.</P> <P>With the rise in the amount of video traffic on the network, coupled with the necessity to react in real-time to business changes, enterprises today are in need of an automated means to dynamically manage QoS priorities even if these priorities do not completely follow best practices.&nbsp; What can network managers do to ensure that their network is constantly evolving to support their business?</P> <H1>QoS dynamism through network programming</H1> <P>What such enterprises need is a way to program network devices on the fly in order to prioritize one type or even a particular application’s traffic over another. One way to accomplish this would be to reconfigure all the devices in the network, but this would require widespread changes and potentially cause unnecessary disruptions. A more intelligent way would be to program&nbsp;specifically just the devices along the path from source to destination to meet the required QoS objectives.<span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 252px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/19599iD05F0F850B079813/image-size/medium?v=1.0&amp;px=400" alt="WiproDLane.png" title="WiproDLane.png" /></span></P> <P>&nbsp;</P> <P>At the last Cisco Live, Wipro demonstrated DLane – their application designed to prioritize business traffic along any path from its source to destination. DLane is part of a larger Wipro initiative around IoT and in particular fleet management for the mining industry.</P> <P>DLane identifies the operator who needs to monitor data streaming from the fleet onto a SAP/HANA cloud in their datacenter. This data is intermittent in nature, which is to stay, it is not flowing all the time, but when it is flowing, the operator needs to access the cloud with the highest priority.</P> <P>DLane uses Cisco DNA Center’s platform capabilities to program the network devices in real time to ensure the policy changes for the priority is enforced in the network. Once the system notifies DLane that&nbsp;priorities needs to be changed, DLane identifies the traffic path and uses <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">DNA Center open APIs</A></SPAN> to configure the devices necessary in the path to recognize and prioritize the operator’s access to the datacenter.</P> <P>Watch Ramesh NG, Director and Practice Head, Software Defined Networking at Wipro explain and demonstrate their use of network programming through DNA Center.</P> <P>&nbsp;</P> <P><LI-VIDEO vid="https://youtu.be/E5wWEoSMl_4" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/E5wWEoSMl_4/hqdefault.jpg" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <P>“We use Cisco DNA as the enabler for our enterprise customers”, says Ramesh, “DNA Center is transforming the way we approach and design software defined access.

For example, the use of collaboration tools to perform network management tasks using mobile devices, or how to integrate the management of IoT and conventional IP network domains. These integrations could have a very powerful impact on OpEx savings and time to response at a business operations level.</P> <P>When looking at this trend, two things come to mind. First, the ability to integrate these technologies physically and how they communicate with each other, and secondly, and perhaps the bigger challenge, is how to coordinate policies that perform cross technology tasks. &nbsp;</P> <P>The <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">open platform nature of DNA Center</A></SPAN> has demonstrated that a single portal can manage disparate domains. However, applications and services are left to manage their policy coordination aspects. To this extent, Italtel has developed a policy management platform branded Netwrapper, which operates on top of DNA Center platform that enables such cross technology policy management.</P> <P>Let’s take an example of how powerful the combination of DNA Center and Netwrapper can be.</P> <H1>Insecurity beyond the corporate office<BR /><span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 292px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/19200iDE094194191B19F5/image-size/medium?v=1.0&amp;px=400" alt="Italtel.png" title="Italtel.png" /></span></H1> <P>&nbsp;</P> <P>You have invested a lot in securing your manufacturing facility. You have installed automatic locks, issued every employee an RFID badge, and outfitted your floor with various sensors. You might now feel that your factory floor is as secure as the data in your corporate office. You might be wrong. You may have state of the art security equipment, but are you leveraging data from the network that connects them together? Are your security personnel alerted to breaches in real-time and are they able to observe and take corrective actions <STRONG><EM><U>quickly</U></EM></STRONG> and prevent the breach from spreading?</P> <H1>&nbsp;</H1> <H1>&nbsp;</H1> <H1>&nbsp;</H1> <H1>Smart devices deserve a smart network</H1> <P>The Netwrapper application makes use of network data coming from DNA Center to address just those shortcomings in the modern physical security infrastructure.</P> <P>Netwrapper utilizes DNA Center’s notification mechanism to receive events from smart devices and sensors connected to the extended enterprise network. It also uses DNA Center’s Intent, or northbound, APIs that provide a programmatic interface to access automation and assurance capabilities of DNA Center. Using these APIs, applications can create workflows combining several repetitive tasks so that engineers can focus on creating solutions instead.</P> <P>In their demonstration, using a simulated factory built of Lego bricks, outfitted with sensors, Italtel showed how authorized personnel could get around unhindered. However, when the sensors detected an unauthorized person or DNA Center found a malfunctioning or disconnected security device, Netwrapper would, shut off the machinery, and initiate a video session for management using WebEx Teams who could view the intrusion and take corrective action. Watch Italtel’s Tullia Zanni and Andrea Stella demonstrate the solution.</P> <P>&nbsp;</P> <P><LI-VIDEO vid="https://youtu.be/Xp2hxJuwZr0" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/Xp2hxJuwZr0/hqdefault.jpg" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <P>“Cisco is enabling partners to get more value from their own capabilities, said Camillo Ascione, Head of Strategic Alliances at Italtel, “Cisco platforms provide the right foundation to create rich and powerful use cases that can address different needs in different vertical markets. After use cases on Collaboration, we are defining specific solutions and architectures spanning from manufacturing to healthcare, all built on the same foundation: the Intent-Based Network.”</P> <H1>Conclusion</H1> <P>Netwrapper exemplifies just the sort of innovative applications that DNA Center open APIs bring to reality for solutions development. Italtel has seamlessly harnessed several Cisco technologies to create a unique policy management value proposition that, when viewed as an OEM technology to build solutions around, can find applicability for many different solutions.</P> <P>Read this <SPAN><A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/dam/en/us/products/collateral/cloud-systems-management/dna-center/nb-09-idc-open-platform-analyst-rpt-ctp-en.pdf" target="_blank">white paper from IDC</A></SPAN> to see how you can leverage network as an open platform and create new revenue opportunities.</P> <P><SPAN><A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/partners/DNAC0007/" target="_blank">Discover this solution</A></SPAN> and others from our <SPAN><A href="http://nomesintegrated.com/?page=https://developer.cisco.com/ecosystem/dnacenter/" target="_blank">DNA Center open platform partners</A></SPAN> and see how they are redefining the future of networking.</P> <H1>Learn more</H1> <P>Learn DNA Center APIs: <SPAN><A href="http://nomesintegrated.com/?page=https://developer.cisco.com/dnacenter/" target="_blank">https://developer.cisco.com/dnacenter/</A></SPAN></P> <P>See how intent-based networking can spark business innovation: <SPAN><A href="http://nomesintegrated.com/?page=https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html" target="_blank">https://www.cisco.com/c/en/us/solutions/enterprise-networks/intent-based-networking-business-innovation.html</A></SPAN></P> <P><SPAN>Read the Cisco Focus Magazine special issue on Intent-Based Networking: </SPAN><A href="http://nomesintegrated.com/?page=https://newsroom.cisco.com/focus/2018/jun/intent-based-networking" target="_blank">https://newsroom.cisco.com/focus/2018/jun/intent-based-networking</A></P> Wed, 26 Sep 2018 13:31:55 GMT https://community.cisco.com/t5/network-architecture-blogs/italtel-uses-cisco-dna-center-to-deliver-cross-technology-policy/ba-p/3713478 vbharga 2018-09-26T13:31:55Z ISE 2.5 Beta Registration is Open https://community.cisco.com/t5/network-architecture-blogs/ise-2-5-beta-registration-is-open/ba-p/3711445 <P style="text-align: center;"><A href="http://nomesintegrated.com/?page=http://cs.co/ise-resources" target="_self"><span class="lia-inline-image-display-wrapper lia-image-align-center" style="width: 144px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/19074iD0E8D438FED7F286/image-size/large?v=1.0&amp;px=999" alt="image.png" title="image.png" /></span></A></P> <P>&nbsp;</P> <P>We are excited to announce the opening of the ISE Beta community for the <STRONG>Cisco Identity Services Engine (ISE) 2.5 Beta</STRONG> for everyone that is a member of the <A href="http://nomesintegrated.com/?page=http://cisco.com/go/ccp" target="_blank" rel="nofollow noopener noreferrer">Cisco Customer Connection Program (CCP)</A>!&nbsp; The ISE 2.5 Beta is scheduled to run from <STRONG>September 26 – November 20, 2018</STRONG>.</P> <P>&nbsp;</P> <P>Downloads, questions and issues are handled within the private ISE Beta.

Therein lies the dilemma, administrators have many tools at their disposal, and yet they are still not able to manage their networks effectively end to end.<span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 152px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/18906i69872EF25F9AF48B/image-size/medium?v=1.0&amp;px=400" alt="HCL-2.png" title="HCL-2.png" /></span></P> <P>HCL showed me at their booth how they solve this problem most elegantly using their NetBot based on-boarding service. This service utilizes Cisco DNA Center to discover a network device and then manages its configuration. HCL demonstrated this capability for Cisco devices and several non-Cisco devices. The service is used in the context of fully automated ITSM tickets that ask for a network device change. Yes, the service can discern that the ITSM ticket is for a network device change, coordinate the change, restore and/or update the device configuration, and close the ticket. It updates all CMDB changes and descriptions in the ITSM tool as well. Full automation of Day 0 ITSM ticket inspections and remedy means network operators don’t have to do this work anymore. And that translates into OPEX savings and faster time-to response.</P> <P>Let’s dig a little deeper into how this service works. NetBot is a network automation framework that automates the complete life-cycle of network devices, from provisioning to policy-based change management, compliance and security administration. <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">DNA Center open platform</A></SPAN> exposes APIs that you can use to build applications that programmatically control the network through DNA Center. So NetBot in this case is working as an application on top of DNA Center.</P> <P>DNA Center uses the concept of device packs, which act like device drivers for network devices, to attach and discover the device. Device packs for Cisco devices, such as routers, switches, and wireless controllers are made available as part of the standard DNA Center product offering. Cisco has also developed an SDK so that packs for other devices can be developed. HCL used the SDK to develop device packs for commonly used third party switches and routers to demonstrate the end-to-end management capabilities of their new service.</P> <P>Furthermore, using DNA Center’s intent-based open APIs, HCL has integrated their NetBot application to both DNA Center and ServiceNow. This means when a ticket is generated in ServiceNow, NetBot can detect the ticket, provision the new box, and retire the ticket, achieving full end-to-end automation of device on-boarding. At the event, HCL showed me how this works in a few simple steps:</P> <OL> <LI>HCL created and deployed a device-pack for a Juniper router on an instance of DNA Center</LI> <LI>A ticket to add a new router is created in ServiceNow</LI> <LI>In response to this service ticket, NetBot used DNA Center services to discover and configure the new router using the Juniper device-pack</LI> <LI>NetBot then relayed the completion status to ServiceNow, added appropriate descriptions to the ticket, and issued a ticket closure</LI> </OL> <P>Watch HCL’s Harmeet Singh, Deputy General Manager &amp; Head of Pre-Sales, describe the value of DNA Center open platform and walk us through a demonstration of how seamless provisioning a non-Cisco device with DNA Center can be.</P> <P>&nbsp;</P> <P><LI-VIDEO vid="https://youtu.be/T06r6CCByww" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="https://i.ytimg.com/vi/T06r6CCByww/hqdefault.jpg" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <P>“At HCL we understand the emerging importance of smart networks and its importance in making a business fast, flexible, and agile”, says Tajeshwar Singh, Senior Vice President and Chief Architect at HCL. “We envision a future where network management can be automated. We specifically created NetBot to tackle networking challenges that enterprises face every day – error-prone manual work, process scalability, time to provision, configure and troubleshoot, and above all vendor lock-in. With the open APIs and SDKs that Cisco’s DNA Center now provides, we saw an opportunity to extend NetBot’s automation capability to solve some of these very issues that vex network administrators every day. This initiative is part of our larger infrastructure blueprint for digital transformation. ”</P> <H1>Conclusion</H1> <P>Cisco has created an ITSM ticket automation framework based on DNA Center that enables multiple services to be deployed to service ITSM tickets. The blog today highlighted one such use case, Day 0 provisioning for any network device, a service offered by HCL. Other Day 1 or Day 2 management services can also be developed that utilize the same framework to automate the service of those ticket requests.

Provisioning network devices is very complex; one small configuration mistake can cause outages and loss of production, not to mention irate users. Even technology-aware people hesitate to mess with it. Now thanks to recent advances in network automation, these routine provisioning tasks are fast, simple, and&nbsp;can be accomplished with dramatically reduced technical knowledge. Now any sort of changes can be confidently, securely, and quickly executed enhancing user satisfaction and productivity.</P> <P>&nbsp;</P> <H1>Network change requests are more frequent and more complex now</H1> <P>Network once provisioned in a certain way, tended to stay that way. When networks were relied on mainly for internal productivity (such as sharing data and emails), the only changes that were required were for departmental and personal changes, which is rather static in machine time. However, today the network has evolved from a simple productivity tool playing an increasingly critical role in an organization’s digital transformation. This has caused a dramatic increase in the number and frequency of changes required of the network. Automation is required to keep pace. Rapid business changes then are good reasons why you need to make your network more agile.</P> <P>Take, for example, the fundamental task of guest WiFi access. In most cases, this access is on a best-effort level without much thought given to quality-of-service and user-experience. However, over time visitors rely more and more on guest network access to help collaborate with internal employees (to perform demonstrations, execute cloud based services, and the like). But as dynamic access rights to guest networks remained a manual operation, which means its slow and sometimes filled with errors, the results are loss of productivity at a high enough level to matter to a business.</P> <P>&nbsp;</P> <H1>Customized experience for each user</H1> <P>At Cisco Live in Orlando, Dimension Data showed an application that they built using intent APIs provided by <SPAN><A href="http://nomesintegrated.com/?page=https://blogs.cisco.com/news/intent-based-networkings-next-evolution-the-dna-center-platform" target="_blank">Cisco DNA Center open platform</A></SPAN>.</P> <P>&nbsp;</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-left" style="width: 159px;"><img src="https://kxiwq67737.i.lithium.com/t5/image/serverpage/image-id/18526i31244A3FEF99C64E/image-size/medium?v=1.0&amp;px=400" alt="DiData.png" title="DiData.png" /></span>They showed that by programmatic control they could create custom experiences for each of their guest WiFi users rather than lumping them all in a common bucket.</P> <P>For example, if a visitor was there to participate in a conference and needed a guaranteed wireless bandwidth, you could create a new wireless SSID for them and provision the network to match their requirements. The application could add new capabilities to their access, if, for instance, they also needed access to local printers.</P> <P>Dimension Data made this application extremely easy to use. Organizations that use it will now be able to free up their technical staff from this mundane but important activity.</P> <P>“Networks were never designed for the Cloud, Big Data, or IoT,” says Kurt Brown, Vice President of Digital Infrastructure at Dimension Data, “What the open platform allows businesses to do is to allow software applications drive the network rather than the other way around. If we want our network to be agile and to evolve with our business, we need an open infrastructure that allows business applications in the network to talk to each other to create the deliver the value that our clients want.”</P> <P>See Kurt demonstrate the solution.</P> <P><LI-VIDEO vid="https://www.youtube.com/watch?v=1XH14J8EMVM" align="center" size="medium" width="400" height="225" uploading="false" thumbnail="" external="url"></LI-VIDEO></P> <P>&nbsp;</P> <H1>Conclusion</H1> <P>With the DNA Center open platform, Cisco has opened the enterprise network for innovation.
