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.

dot1dBasePortIfIndex.26 = 10102
]



And on switche where there is the issue :

CMD[/usr/bin/snmpbulkwalk -v2c -c *** -Pu -OQUs -m BRIDGE-MIB -M /var/www/observium/mibs/rfc:/var/www/observium/mibs/net-snmp 'udp':'2.58.65.161':'161' dot1dBasePortIfIndex]

CMD RUNTIME[0.0404s]
STDOUT[
dot1dBasePortIfIndex.1 = 10001
dot1dBasePortIfIndex.22 = 10022
dot1dBasePortIfIndex.25 = 10101
dot1dBasePortIfIndex.26 = 10102
dot1dBasePortIfIndex.64 = 5001
]


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 :)

 What's interface id 8 on your device? snmpget ifName.8 maybe. Is it an

 They appear without portID on the "vlans_fdb" table and so, not present on the web GUI.
 
 Do you know why their is no port ID ?

 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.
