Hello,
A customer is having the following problem on severals sites.
After a reload, some cat6000-sup1a-withoutMSFC and some cat2948G all running release 7.4.3 lose some part (not all) of the configuration, after a reload.
Sometime the vlan configuration vanished, some other time the SNMP configuration disappeared.
Does anyone already get this kind of problem ?
I found no bug on the bug tools or on the RN for 7.4.x.
Regards,

Never heard anything like that. Can you post the following command results?
show boot
show bootvar

For how long were the switches up before? We have one NVRAM corruption bug

If you are running into this, you would "checksum failure" in the output of sh ver prior to reload.
I suggest that you upgrade CAT OS to latest 7.6(x) which is general deployment. Note that your Sup1a in 6500 needs 128MB DRAM to run 7.6 code.

Hello Prashanth,
I'll go on looking on this way for the cat6000.
What about cat2948G ? Could this bug also match for cat2948g ?
Best regards,

Yes. This bug affects all CAT OS based platforms.

Hello Prashanth,
On one cat6X00, the sh version from the sh tech do not show me any checksum failure, but I can find this on the "sh log" from the console port after a reload (and loosing some part of configuration):
Console> (enable) show logg buff 1023

So this cat6x00 could match this bug. Do you aggree with me ?
