dot1sCistPortProtocolMigration

Module: AT-GS950-8-MIB

OID (symbolic): AT-GS950-8-MIB::dot1sCistPortProtocolMigration

OID (numeric): 1.3.6.1.4.1.207.1.4.165.118.1.6.1.11

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 dot1sCistPortProtocolMigration?

This writable OID, when set to TRUE while the switch is running RSTP or MSTP, forces the port to transmit MST BPDUs without instance-specific information, triggering a protocol migration check. It is used to manually restart the negotiation process when connecting to legacy or mixed-version spanning tree environments.

Examples

snmpwalk -v2c -c public <target> AT-GS950-8-MIB::dot1sCistPortProtocolMigration

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.207.1.4.165.118.1.6.1.11.1
snmpget -v2c -c public <target> AT-GS950-8-MIB::dot1sCistPortProtocolMigration.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.207.1.4.165.118.1.6.1.11.1 s <value>
