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 and 'mstp(3)' indicates the Multiple Spanning Tree Protocol Specified in IEEE 802.1s.

What is nnMstForceProtocolVersion?

Sets which Spanning Tree Protocol version the bridge runs: STP-compatible (802.1D), RSTP (802.1w), or MSTP (802.1s). Defaults to MSTP.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.18
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstForceProtocolVersion

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.18.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstForceProtocolVersion.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.1.18.1 i <value>
