ieee8021MstpTopologyChange
Module: IEEE8021-MSTP-MIB
OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpTopologyChange
OID (numeric): 1.3.111.2.802.1.1.6.1.2.1.6
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: In an MSTP Bridge, the Topology Change parameter value: true(1) if tcWhile is non-zero for any Port for the MSTI.
What is ieee8021MstpTopologyChange?
True if a topology-change timer (tcWhile) is currently active on any port for this MST Instance, meaning the instance recently changed its forwarding topology and is still propagating that change.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.6 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpTopologyChange
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.6.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpTopologyChange.1
