bridgePathCost

Module: ACMIB

OID (symbolic): ACMIB::bridgePathCost

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.8.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The contribution of this port to the path cost of paths towards the spanning tree root which include this port. 802-1D-1990 recommends that the default value of this parameter be in inverse proportion to the speed of the attached LAN.

What is bridgePathCost?

Assigns a cost metric (0 to 65535) for this port's contribution to the spanning tree path, with lower values indicating faster or preferred paths. Administrators configure this to bias the spanning tree algorithm toward faster or redundant links and away from congested or slow links. A value of 10 on a gigabit port indicates a low cost (preferred), while 100 on a slower link indicates a higher cost (less preferred).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.8.1.6
snmpwalk -v2c -c public <target> ACMIB::bridgePathCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.8.1.6.1
snmpget -v2c -c public <target> ACMIB::bridgePathCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.8.1.6.1 i <value>
