Description: The cost of the path to the root from this bridge.
What is nb30DeviceRootCost?
The spanning-tree path cost from this bridge to the root bridge. A sudden change here often coincides with a topology change event as the network re-routes around a failed link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.1.6.12.1.21 snmpwalk -v2c -c public <target> NB30MIB::nb30DeviceRootCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.1.6.12.1.21.1 snmpget -v2c -c public <target> NB30MIB::nb30DeviceRootCost.1
