[rancid] Issue with nx-os after switch upgrades

That fixed, but only after I also commented out several of the “show vdc” commands in the command-table which didn’t apply to either our Nexus 5K’s or our MDS switches.  Just in case we might have VDC’s in the future, I ended up doing this on a copy of the current nxrancid script named nx56-mds-rancid and then added that as a type called cisco-nx56-mds in the rancid-fe file.

Thanks, everything seems to be working now!

John

Sorry. Should have included the diff:

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.
