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 an...
Do you have technology silos in your organization? 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 ...
Big corporations think big! 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 hand...
Here is a freebie from the live Ask The Expert session "DNA Platform
Features and Capabilities." This is a sample, self-contained, and ultra
simple Python 2.7 script that will allow you to retrieve the information
that DNA Center is using to manage a spec...
Programming is a trending topic in the world of networking. However, to
a lot of us network engineers, it feels like writing such programs can
be hard to do. Thinking that it would need a lot of time and skill, we
consider programming suitable only for la...
The promise of a network that can detect problems on its own, lets IT
management system know, debugs and isolates the problem, seeks
permission to rectify it, and then actually goes out and does it, must
feel like utopia! Surely, this is the stuff of the ...
Anyone who has ever poured over enormous amounts of data from syslogs,
Wireshark, and debug dumps from individual devices can relate to this
very well. There’s got to be a better way to identify trouble spots in
the network. With the network playing an in...
Data traffic control generally follows a static set of rules with
assigned network priority levels – from best effort for web and email to
the highest levels reserved for signaling and real-time media. In the
past, QoS traffic classification worked well b...
One of the most fascinating trends I saw at Cisco Live in Orlando was
how abstraction and automation of the network can lead to seamless
integration with other technologies in order to achieve significant
operational workflows. For example, the use of col...
If you are a network administrator, you know how tedious it can be to
manage a mixed-vendor network. There are always differences in how
devices are discovered, monitored, configured, and updated. There are
also likely to be a variety of management applic...
When it comes to configuration changes in your production network, I
think you’ll agree that it traditionally has been a job best left for
“the pros”. Provisioning network devices is very complex; one small
configuration mistake can cause outages and loss...
Imagine it is Tuesday afternoon and your child is asking you to come to
their soccer game to cheer them on. Of course, you want to attend, but
that would mean you would have to leave the network you manage “behind”
at one of the busiest times in the week....
I was copying an pasting some configs between two nexus devices and some how fat-fingered something and the admin user can no longer login to the command line. I can still login as the root user and run an "su admin" and login to the device that way...
Per this link, the GLC-SX-MMD should be compatible with the ISR4321/K9
However, this is the e...
