Aha, you have fallen for one of the classic blunders. Never assume that a
CISCO OID that's supported on one device will be supported on another,
especially if one of those devices is a router and the other is a switch.
For Cisco MIBs:
Go to http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Pick your device from the appropriate list, in this case, LAN switches. You
will get back a list of supported MIBs related to software versions. This
is where is gets tricky...you kind of have to know what you're looking for
to be able to find it. Here's a hint: Try CISCO-PROCESS-MIB first. :)
To get the fully-qualified OIDs, go back out to the main page, and go to the
"OIDs" link. From there, go to CISCO-PROCESS-MIB again, and look up the OID
name. This is a little easier and more accurate than trying to figure it
out from the MIB itself IMO.
If you missed my post about the temperature the other day: I'd recommend
walking this section of the mib from the command line to familiarize
yourself with your data instead of just blindly plugging in OIDs.
