I have inherited 4 C6509s running Native IOS 12.1(7)E on two and 12.1
(5c)E on the other two. All switches have redundant SUP1A-2GEs with
MSFCs and PFCs. Whenever you make a change and write the config to
NVRAM, the switch crashes within hours. Both SUP1A-2GEs become active
and neither forwards traffic. The workaround is to make changes and
defer writing to NVRAM. They write to NVRAM off-hours and immediately
cycle power to avoid this problem. Anyone ever seen this happen?
Also, some related Native IOS questions:
1. 'show modules' only displays modules in slot 1 - 5, not in 15 and 16
as I would expect. I understand that's because I am running native,
but I don't see any Sub-module information listed that confirms I even
have an MSFC and/or PFC installed. How do I verify without removing
line cards? (I am 'told' I do have MSFCs and PFCs, and I am running
Native IOS, so...)
2. And the output from 'show modules' also displays the SW on these
line cards as 6.1(0.105)OR - What does that mean? And does this need
to be a specific revision to match the IOS used? (See next question).
3. How do I know what software (i.e. firmware, software, boot loader)
to load on the MSFC and or SUP1A-2GE to match the IOS you are using?
Any assistance would be greatly appreciated!
Joe
