Description: The port number of the port that offers the lowest cost path from this Bridge to the root Bridge.
What is ieee8021SpanningTreeRootPort?
The port number on this bridge that offers the lowest-cost path to the root bridge — i.e., which physical port this switch considers 'toward' the root.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.1.1.8 snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeRootPort
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.3.1.1.1.8.1 snmpget -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeRootPort.1
