What is mstpPortAdminExternalPathCost?

This OID is the admin-configured external path cost for the port (0-200000000), used outside the MST region; a value of 0 tells the bridge to auto-select a cost based on the port's link speed instead. Admins override this to manually bias which uplink is preferred toward the CST root.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6027.20.2.11.1.5
snmpwalk -v2c -c public <target> FORCE10-MSTP-MIB::mstpPortAdminExternalPathCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6027.20.2.11.1.5.1
snmpget -v2c -c public <target> FORCE10-MSTP-MIB::mstpPortAdminExternalPathCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.6027.20.2.11.1.5.1 i <value>
