nnRstDot1dStpPathCostDefault

Module: NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB

OID (symbolic): NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpPathCostDefault

OID (numeric): 1.3.6.1.4.1.45.5.4.1.1.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The version of the Spanning Tree default Path Costs that are to be used by this Bridge. A value of 8021d1998(1) uses the 16-bit default Path Costs from IEEE Std. 802.1D-1998. A value of stp8021t2001(2) uses the 32-bit default Path Costs from IEEE Std. 802.1t.

What is nnRstDot1dStpPathCostDefault?

Selects whether the bridge computes default Spanning Tree path costs using the older 16-bit values from 802.1D-1998 or the newer 32-bit values from 802.1t, which an admin sets to match the path-cost convention used by the rest of the spanning-tree domain.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.1.1.3
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpPathCostDefault

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.1.1.3.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpPathCostDefault.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.4.1.1.1.3.1 i <value>
