What is stRootCost?

This read-only INTEGER, though its source description is empty, reports the accumulated spanning tree path cost from this bridge to the current root bridge. An administrator watches for a rising value after a link change as a sign that traffic is now taking a longer path to reach the root. For example, after a preferred uplink fails over to a backup link, the admin sees stRootCost increase, confirming spanning tree recalculated onto a higher-cost path.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.97.3.3.4.8
snmpwalk -v2c -c public <target> CTATX-MIB::stRootCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.97.3.3.4.8.1
snmpget -v2c -c public <target> CTATX-MIB::stRootCost.1
