What is ieee8021SpanningTreePortDesignatedPort?

The Port Identifier of the port on the segment's Designated Bridge, letting you trace exactly which remote port this one is deferring to.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.10
snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortDesignatedPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.10.1
snmpget -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortDesignatedPort.1
