Description: (Copied from draft-ietf-bridge-rstpmib-02.txt). The version of the Spanning Tree default Path Costs that are to be used by this Bridge. A value of pathCostDefault8021d1998(1) uses the 16-bit default Path Costs from IEEE Std. 802.1D-1998. A value of pathCostDefault8021t2001(2) uses the 32-bit default Path Costs from IEEE Std. 802.1t.
What is mstpGenPathCostDefault?
This OID selects which default port-cost table the bridge uses when a port's path cost is set to auto-calculate: the legacy 16-bit costs from IEEE 802.1D-1998 (pathCostDefault8021d1998) or the newer 32-bit costs from 802.1t (pathCostDefault8021t2001). An admin sets this to keep cost calculations consistent with other bridges in the same spanning tree, since mismatched cost scales can distort root/path selection.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6027.20.2.10.18 snmpwalk -v2c -c public <target> FORCE10-MSTP-MIB::mstpGenPathCostDefault
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6027.20.2.10.18.1 snmpget -v2c -c public <target> FORCE10-MSTP-MIB::mstpGenPathCostDefault.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.6027.20.2.10.18.1 i <value>
