Description: The cost of the path to the root as seen from this Bridge.
What is ieee8021SpanningTreeRootCost?
The total path cost from this bridge to the root bridge, as currently computed by Spanning Tree; useful for verifying traffic is taking the expected path to the root.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.1.1.7 snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeRootCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.3.1.1.1.7.1 snmpget -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeRootCost.1
