Hmm, odd.
The behaviour of these tables is likely to sometimes be buggy, since very very few people ever poll them.
I'm not sure if this actually is buggy, or if were just not quite understanding something, though.

The only difference in term of config between these 2 switches is that almost all ressources are on the native vlan (vlan1) on the switch on which the fdbtable is complete ...
Thanks again for your help.

This is because these two indexes aren't the same, afaik dot1d
doesn't use the same indexing as
ifTable.
There's an intermediate index, but I can't remember where it is :)

Hello all,
First of all, i would like to tanks all people that made this
great tool ! :)
I'm still preparaing the migration from our old tool to Observium. So, i am playing/testing it with some Cisco devices.
A strange thing that i observed is that the FDB tables show mac
addresses on switch interfaces that
are in trunk mode only (dot1Q flagged).
Do i need to setup or declare something somewhere ?
Thank in advance for your help.
