Nexus 7000 and the Show Tech command (gzip too)

Fryguy — Tue, 25 Jan 2011 13:18:24 +0000

Recently I have experience some interesting first-level support from our Cisco VAR. They are not too familiar with the Nexus 7000 and insisted on us sending them a SHOW TECH from the switch. If you are not familiar with a Nexus 7000, let me tell you – the show tech from this box can be over 100 Megs! So, when they asked for that I was like – are you sure? really really sure? I just have to say – thank you DropBox and public folders! I used DropBox place the file and then send the support the public link. Not sure that most e-mail systems would appreciate that large of a file!
So, if the Show Tech Support is so big, how do you get the information that support needs? Well, instead of running a complete show tech, you run it for the sections you need!
Here is a list of what you can append to a Show Tech-Support command: (show tech-support option)
N7K1-CoreSwitch1# sh tech-support ?

Ok, color code again:
Red – Router Output
Blue – Commands
Green – Notes
Traditionally when we have done show tech-support, we have always done terminal length to 0, set the capture buffer on our terminal application, and then executed the command – like this:
First we set the length to 0
FryGuyR1#terminal length 0
Then we configure our terminal to capture the data

CCIE Rack vbs script for SecureCRT

Well I finally got around to writing a script in order log into all my lab routers. Why? I got tired of typing R1, then password, breaking out and going to the next. When you connect to 8 routers for every lab, it takes time.
So, below is the script I use for my SecureCRT session. Pretty simple, just did a record of the first two and then edited the rest of them in.
It can also be found here for easier reading:
