Module: RAD-MIB

OID (symbolic): RAD-MIB::prtLanWanStpCost

OID (numeric): 1.3.6.1.4.1.164.3.2.3.2.22.1.1.9

Node type: OBJECT-TYPE

Type: Integer32

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 prtLanWanStpCost?

This object sets the Spanning Tree Protocol (STP) path cost for a port, determining how much the port will contribute to the overall network topology cost toward the root bridge. Lower costs make a port more likely to forward traffic and less likely to be blocked by STP. Network engineers adjust this value per IEEE 802.1D recommendations to favor faster links and balance topology decisions across heterogeneous network speeds.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.164.3.2.3.2.22.1.1.9
snmpwalk -v2c -c public <target> RAD-MIB::prtLanWanStpCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.164.3.2.3.2.22.1.1.9.1
snmpget -v2c -c public <target> RAD-MIB::prtLanWanStpCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.164.3.2.3.2.22.1.1.9.1 i <value>
