2621 nvram

Hi,

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.

Thanks.

Likely a cosmetic IOS bug that you can ignore if everything else works normally.

Re: 2621 nvram

This pertains to the NVRAM file "ifindex-table", which is:

Interface Index Table

It is a file that contains a matrix with numerical values assigned to each interface on the device. It looks like it is mostly related to SNMP for tracking the names of interfaces for polling.

Here are a few links that might clear this up:

http://supportwiki.cisco.com/ViewWiki/index.php/What_is_interface_index_(ifindex)_persistence%3F

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:
