swMSTPPortExternalPathCost
Module: MSTP-MIB
OID (symbolic): MSTP-MIB::swMSTPPortExternalPathCost
OID (numeric): 1.3.6.1.4.1.171.12.15.2.4.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The contribution of this port to the path cost of paths towards the CIST root which include this port.
What is swMSTPPortExternalPathCost?
This read-write value (0-200000000) sets this port's contribution to the path cost of routes toward the CIST root that pass through it. Admins lower this value on higher-bandwidth uplinks so spanning tree prefers them over slower paths.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.4.1.5 snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPPortExternalPathCost
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.4.1.5.1 snmpget -v2c -c public <target> MSTP-MIB::swMSTPPortExternalPathCost.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.15.2.4.1.5.1 i <value>
