nnRstDot1dStpVersion

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

OID (symbolic): NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpVersion

OID (numeric): 1.3.6.1.4.1.45.5.4.1.1.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The version of Spanning Tree Protocol the bridge is currently running. The value 'stpCompatible(0)' indicates the Spanning Tree Protocol specified in IEEE 802.1D and 'rstp(2)' indicates the Rapid Spanning Tree Protocol specified in IEEE 802.1w. New value may be defined as future versions of the protocol become available.

What is nnRstDot1dStpVersion?

Selects whether the bridge runs the legacy 802.1D Spanning Tree Protocol (stpCompatible) or 802.1w Rapid Spanning Tree (rstp), which an admin sets to rstp -- the default -- to get RSTP's much faster convergence after a link change.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.1.1.1
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpVersion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.1.1.1.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1dStpVersion.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.4.1.1.1.1.1 i <value>
