tpMstpInstancePortPathCost

Module: TPLINK-SPANNING-TREE-MIB

OID (symbolic): TPLINK-SPANNING-TREE-MIB::tpMstpInstancePortPathCost

OID (numeric): 1.3.6.1.4.1.11863.6.21.1.3.3.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Path Cost is used to choose the path and calculate the path costs of ports in an MST region. It is an important criterion on determining the root port. The lower value has the higher priority.

What is tpMstpInstancePortPathCost?

This port's path cost (0-2000000) within the specific MST instance identified by tpMstpInstancePortConfigId; a lower value gives the port a better chance of being chosen as the root port for that instance.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11863.6.21.1.3.3.1.4
snmpwalk -v2c -c public <target> TPLINK-SPANNING-TREE-MIB::tpMstpInstancePortPathCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.11863.6.21.1.3.3.1.4.1
snmpget -v2c -c public <target> TPLINK-SPANNING-TREE-MIB::tpMstpInstancePortPathCost.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.11863.6.21.1.3.3.1.4.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tpMstpInstancePortPathCost.1
