bridgeDomainRootCost
Module: ACMIB
OID (symbolic): ACMIB::bridgeDomainRootCost
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The cost of the path to the root as seen from this bridge.
What is bridgeDomainRootCost?
This OID shows the cumulative path cost from this bridge to the spanning tree root, calculated by summing the costs of all links along the best path. Engineers monitor this value to verify that the spanning tree algorithm is choosing optimal paths and to detect routing anomalies. A high value like 400 suggests a long or slow-speed path to root, while a low value like 50 indicates a direct or fast connection.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.7 snmpwalk -v2c -c public <target> ACMIB::bridgeDomainRootCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.7.1 snmpget -v2c -c public <target> ACMIB::bridgeDomainRootCost.1
