The OID for the object “interface” is “1.3.6.1.2.1.2”

i checked this oid, but the output don't show me which interface is assigned to an etherchannel (port-channel), or am i blind?

For LACP I found two interesting objetcts in IEEE8023-LAG-MIB:



IEEE8023-LAG-MIB::dot3adAggPortSelectedAggID.28 = INTEGER: 337

IEEE8023-LAG-MIB::dot3adAggPortSelectedAggID.82 = INTEGER: 337


IEEE8023-LAG-MIB::dot3adAggPortAttachedAggID.28 = INTEGER: 337

IEEE8023-LAG-MIB::dot3adAggPortAttachedAggID.82 = INTEGER: 337


ifName.28 = Gi2/4

ifName.82 = Gi3/10

ifName.337 = Po1



#show etherchannel 1 summary

Group  Port-channel  Protocol    Ports

------+-------------+-----------+-----------------------------------------------

1      Po1(SU)         LACP      Gi2/4(P)       Gi3/10(P)
