snmp mib index changed.

Answered Question

After upgrading the IOS on a c3825, I found the index of the snmp parameters for FXO changed. This is inconsistent with my knowledge, in that i thought those parameters would never change for a router.

What am i missing?


Thank you!

You can try "snmp-server ifindex persist".This should keep the snmp indexd same.

Hello Han,

we had the same issue some years ago:


even if we had configured

snmp mib ifindex persist


after a major change release the SNMP indexes were changed.


Cisco answer was that when the command is there to ensure that after a reload the indexes are consistent but when changing IOS this is not guaranteed in case of upgrade


Hope to help

Giuseppe
