[rancid] Issue with nx-os after switch upgrades

Wed Mar 4 22:37:59 UTC 2015

I had a similar problem with nxrancid. I ended up modifying the script in
the ShowVersion sub to return(1) for Invalid input detected rather than -1.

The issue is that some of the commands will only show up with certain
hardware ("show vdc all" doesn't work on anything other than a Nexus
7000/7700) or unless certain features have been enabled ("show fex" only
works when "feature fex" has been enabled). It's a hack, but I thought that
it was the easiest solution without creating a command list for every
variable of hardware/configuration.
