dot1dTpFdbEntry contains three entries and is indexed by dot1dTpFdbAddress.
dot1dTpFdbEntry OBJECT-TYPE
SYNTAX Dot1dTpFdbEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"Information about a specific unicast MAC address
for which the bridge has some forwarding and/or
filtering information."
INDEX { dot1dTpFdbAddress } <--
::= { dot1dTpFdbTable 1 }
Dot1dTpFdbEntry ::=
SEQUENCE {
dot1dTpFdbAddress <--
MacAddress,
dot1dTpFdbPort <--
INTEGER,
dot1dTpFdbStatus <--
INTEGER
}
1) So you need to poll dot1dTpFdbPort to get the port index number.
nms-server2:/mibs> snmpwalk -c public@6 14.32.6.12 dot1dTpFdbPort
BRIDGE-MIB::dot1dTpFdbPort.0.1.66.69.224.255 = INTEGER: 2
BRIDGE-MIB::dot1dTpFdbPort.0.2.126.248.168.87 = INTEGER: 2
BRIDGE-MIB::dot1dTpFdbPort.0.2.185.144.76.102 = INTEGER: 385 <-- portIndex is 385
2) so port index is 385, what's the ifIndex for that port?
nms-server2:/mibs> snmpwalk -c public 14.32.6.12 dot1dBasePortIfIndex | grep 385
BRIDGE-MIB::dot1dBasePortIfIndex.385 = INTEGER: 101 <-- ah, ha, ifIndex is 101
3) now ifIndex is 101, what port is it?
nms-server2:/mibs> snmpwalk -c public 14.32.6.12 ifName | grep 101
IF-MIB::ifName.101 = STRING: 4/1 <-- it's port 4/1
4) verify from CLI
