2621 nvram

Unanswered Question

Has anyone ever come across this error message on a 2821 router during boot ?

% Error opening nvram:/ifIndex-table No such file or directory

I can't seem to find anything in cco that explains this error message.

Any advice appreciated.


I have this problem too.

Here are a few links that might clear this up:


The Feature navigator describes it as:

Interface Index Persistence Maintain correspondence between ifIndex values and actual interfaces across reboots.

This will describe it in detail:
