SNMP problem with 3925 15.1(4)M: Invalid ifIndex for GigabitEthernet0/2

Stefan Giera · ‎06-08-2011

Hi there,

I have a strange problem concerning a Cisco 3925:

Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version

15.1(4)M, RELEASE SOFTWARE (fc1)

(c3900-universalk9-mz.SPA.151-4.M.bin)

This router has 3 native interfaces:

Gi0/0 (RJ45)

Gi0/1 (RJ45/SFP)

Gi0/2 (RJ45/SFP)

I have built in an additional EHWIC-1GE, which is named as Gi0/0/0.

When I do:

>rtr#sh snmp mib ifmib ifindex GigabitEthernet 0/1

>Interface = GigabitEthernet0/1, Ifindex = 3

=> everything is fine.

When I do the same for Gi0/2, it says:

>rtr#sh snmp mib ifmib ifindex GigabitEthernet 0/2

>Invalid ifIndex for GigabitEthernet0/2

=> There must be a bug in the MIB within this IOS, but I cannot find anything in the Cisco Bug Tool Kit.

This output might be interesting, too:

>rtr#sh snmp mib ifmib ifindex

>GigabitEthernet0/1: Ifindex = 3

>GigabitEthernet0/0/0: Ifindex = 5

>Backplane-GigabitEthernet0/3: Ifindex = 1

>Loopback0: Ifindex = 7

>Embedded-Service-Engine0/0: Ifindex = 4

>Null0: Ifindex = 6

>GigabitEthernet0/0: Ifindex = 2

Is anyone else experiencing this problem?

Do I have to configure something to avoid this behaviour?

Thanks in advance for any help ;-)

This is a bug which is fixed by CSCto03506. This fix will be in 15.1(4)M1 when it is released.
