Major Description
None of the devices I own have ifIndexes that begin with 0 (arista, HP, brocade/foundry). Mainly noticed this with my Brocade devices as the vlan to port mappings were off.
I've attached a patch that uses the $vlan_ifindex_map someone setup but didn't complete implementation. This patch looks in the lowest index of $vlan_ifindex_map for the dot1dBasePortIfIndex to determine the lowest possible ifIndex and adds that to the index used to assign vlans found to ports as an offset.
I recommend not blindly accepting this patch and testing it in your own environment to ensure it doesn't break your stuff.

our HP switches are the smaller kind, 2650, 2610, 2824. I don't have any larger HP switches to test with. Question, are the indexes off for your 5400 and 8200 prior to the patch?.
Hi
I tried this patch and Observium-964 on my test environment. We have lots of HP ProCurve and the patches fixes vlan mapping on smaller switches (< 48 ports) likes 2510,2520,2650 etc, but on larger switches 5400, 8200 the indexes are off.
Will try to do some more troubleshooting on this later today.
What kind of HP switches do you run ?
Ok there is no bug in brocade's Q-BRIDGE-MIB implementation, I've tracked down another bug in observium which led me to believe this. I will file another bug.
I also believe that brocade's Q-BRIDGE-MIB implementation is generally broken so compare before and afters if you are testing with brocade switches (Non NOS).
having two open issues made it confusing enough that no one wants to read about it.
i have no idea what needs to be applied, what fixes what, or anything.
