I recently performed a Compact Flash Memory upgrade on my 6509. Everything is functioning normally with the exception of SNMP. I am using MRTG to monitor the bandwidth on a few key interfaces. Since the upgrade (I upgraded the MSFC and Supervisor images, and the SP and RP ROMMON), I am getting a lot of "No such name" errors when I do a "show snmp". The SNMP configuration has remained the same, and I have even disabled and re-enabled SNMP with the same community string and settings.
My old images: c6msfc3-psv-mz.122-17d.SXB11a.bin, s72033-psv-mz.122-18.SXD7.bin
My upgrades: c6ksup3-rm2.srec.8.4.2, c6msfc3-rm2.srec.122-17r.S4, c6msfc3-ipservicesk9_wan-mz.122-18.SXF7.bin, s72033-ipservicesk9_wan-mz.122-18.SXF7.bin
Has anyone else ever recieved these errors? If so, how would you fix these?

Try looking at what interface indexes are.
CORE#sh snmp mib ifmib ifindex
Control Plane Interface: Ifindex = 487
EOBC0/0: Ifindex = 388
FastEthernet3/1: Ifindex = 1
FastEthernet3/10: Ifindex = 10
FastEthernet3/11: Ifindex = 11
FastEthernet3/12: Ifindex = 12
Then reference what MRTG thinks the interface index is (check your config file). What probably happened was the indexes changed (they can with new interfaces/vlans. etc) when you rebooted the switch. You can 'hardcode' the indexes by entering-
CORE#snmp-server ifindex persist
HTH and please rate.

Thanks a lot! A couple of the Ifindexes stayed the same, but the majority of them changed. I appreciate the help!

What MIB objects are you polling?
Could it be that the instances have changed since you reloaded?
