Insieme

Back at Cisco Live 2013, there was some chatter around the Insieme deal and the potential to see a new switch from Cisco during the event.  I think even Greg over at EtherealMind was hoping for some more juicy Insieme announcements at Cisco Live as well ( see post –  http://etherealmind.com/musing-predicting-what-insieme-might-announce-at-cisco-live/ )Well, what we actuall got at Cisco Live was the Nexus 7700 switch and the Gold Cisco 6608 Catalyst Switches, not the hoped for Insieme switch.

Then today I saw that there an article posted over on NetworkWorld ( http://www.networkworld.com/news/2013/100213-interop-cisco-insieme-274455.html ) in regards to the Insieme Nexus 9K and Hardware Defined Networking that caught my attention. There is another article there –  http://www.networkworld.com/community/blog/cisco-nexus-9000-aimed-40g –  that has some output from a 9508 switch as well.

Time to continue the Author Series of posts, this time with Ron Fuller, CCIE 5851.   It is the intention of these interviews to bring a human side to the technical author.  I feel that each author has a story to share , and I wanted to provide them a way to share that story.

Cisco Nexus Show Tech-Support – aka TAC-PAC

tac

The inevitable TAC call and the request for a Show Tech to help with the support. Normally this is not a big problem on most systems, but if you ever try this on somehting like a Nexus 7000 – it takes a loooooong time and pulls well over 100 megs of information in that file. Capturing this output to a terminal is a test of patience (lets not mention console), or even if you redirect it to the bootflash it can still take some time. Then, there is getting a 100+ meg file copied from the bootflash to your computer, etc etc etc. I did do a quick post some time ago about using GZip to compress the file – you can find that post here.

But that is not what this post is about, this post is about a command called TAC-PAC. TAC-PAC seems to be a little known command to most people who have never run into a problem and had to pull a show tech of a N7K, of for that matter any NX-OS platform. I was able to confirm this command on Nexus 7000, 5000, and 1000 as well as the SAN MDS.

So, what is TAC-PAC? It is a single command that redirects the output of show tech-support details to a file, and then automatically compresses it for you. One command – nice and simple. The only thing that you will still have to do is pull the file via FTP or so.
