swMSTPMstPortInternalPathCost

Module: MSTP-MIB

OID (symbolic): MSTP-MIB::swMSTPMstPortInternalPathCost

OID (numeric): 1.3.6.1.4.1.171.12.15.2.5.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This is the value of this port to the path cost of paths towards the MSTI root.

What is swMSTPMstPortInternalPathCost?

This read-write value (0-200000000) sets this port's contribution to the path cost of routes toward the MSTI root, for this specific MSTP instance. Admins tune this per-instance to influence which port becomes the preferred uplink for a given VLAN group's tree, independent of the CIST's path cost.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.5.1.4
snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPMstPortInternalPathCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.5.1.4.1
snmpget -v2c -c public <target> MSTP-MIB::swMSTPMstPortInternalPathCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.15.2.5.1.4.1 i <value>
