I've written a PERL script which upgrades the image on a CatOS device; now I want to extend this script to support IOS devices.
But I'm having trouble finding an SNMP variable which reports the name of the currently running image in an IOS device.
Any pointers?
For the CatOS, "sysBootVariable.0" does this nicely, returning a string which looks like "bootflash:cat4000-cv.5-5-11.bin".
I've found "sysConfigName.0", from the OLD-CISCO-SYSTEM-MIB, and this returns the information I want in some of my older Cisco devices ... and even on my Catalyst 35xx boxes ... but this string is empty on MSFCs. And I'm not thrilled about using variables from this MIB; it has the word "deprecated" all over it.
The "ceExtSysBootImageList.0" variable from CISCO-ENTITY-EXT-MIB looks promising ... but I don't think that the MSFC supports this MIB.
The CISCO-SYSTEM-MIB seemed like a reasonable place to find such a variable ... but I don't see anything resembling what I want in it.
CISCO-IMAGE-MIB is very promising ... but I don't understand the answer I'm getting.
Here is output from an snmpwalk on one of my MSFCs ("cf-a-rtr").

I don't understand these CW_XXXX tokens ... how can I translate them into something which looks like "bootflash:c6msfc-dsv-mz.121-8b.E7.bin"?
If you know how to acquire the name of the currently running image on an MSFC, please let me know.

If it's the IOS version you are looking for it's available from MIB-II.
