nnMstCistPortProtocolMigration

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

OID (symbolic): NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistPortProtocolMigration

OID (numeric): 1.3.6.1.4.1.45.5.5.1.3.1.11

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: Indicates the Protocol migration state of this Port. When operating in RSTP/MSTP (version >= 2) mode, writing TRUE(1) to this object forces this port to transmit MSTP BPDUs without instance information. Any other operation on this object has no effect and it always returns FALSE(2) when read.

What is nnMstCistPortProtocolMigration?

Writing true forces this port, while running RSTP/MSTP, to transmit MSTP BPDUs without instance information; any other write has no effect, and reading it always returns false.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.3.1.11
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistPortProtocolMigration

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.3.1.11.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistPortProtocolMigration.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.3.1.11.1 s <value>

SNMPv3 example:

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