Redirecting Cisco Show Command Output
Have you ever issued a diagnostic command on a Cisco device and wish you could keep the output to review off line at a later time? There actually is a way to do this! (without copying and pasting, etc). I recently was asked to send the results of “show tech-support” to Cisco’s TAC to get help with an issue. To my dismay the result of this command overran the length of the terminal window’s buffer. Rather than changing things on my side I knew this was the opportunity I needed to make my life easier. To send output directly you … Continue reading

Authenticating APC Network Management Cards with Network Policy Server
Working in a large environment with 100% power availability as a requirement I have had the experience of working with many APC UPS systems. We typically monitor the UPS remotely and from time to time have to log in to check statuses or review errors. Our environment frowns upon shared credentials as do I so authentication to these systems had to be updated. I knew we had options because I had seen RADIUS authentication listed in the specifications for the management card. Initially I created a fairly vanilla policy and was able to log into the APC’s. The issue, however, … Continue reading
Cisco Configuration “Expect” Backup Script
I was recently tasked with backing up switch configurations automatically. No problem, right? Wrong.

I had made a telnet script in the past but was not crazy about passwords flying around in plain text. I really have very little scripting experience so many of you will find this very easy to understand and follow since there is nothing complicated about my scripting skills.

Remote Cisco Router Change Safty Net
In the networking world you have a lot of opportunity to break things and take down entire buildings, WAN links, etc. Even less risky changes can result in a short break in connectivity while routing protocols re converge and so on. Because we often don’t have physical access to both sites while we are making WAN changes there has to be some type of worst case scenario prevention method. This is it: When making changes to WAN links in particular I always like to make the change to the far side first and obviously have to if there will be … Continue reading
