What is rldot1sMstpInstanceTopChanges?
This read-only counter accumulates the total number of topology change events detected by a specific MSTP (Multiple Spanning Tree Protocol) instance. Topology changes indicate bridge failures, port state transitions, or reconfiguration events in the spanning tree. Operators monitor this to track network stability and investigate frequent topology instability.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.89.57.6.1.1.4 snmpwalk -v2c -c public <target> Dell-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstanceTopChanges
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.89.57.6.1.1.4.1 snmpget -v2c -c public <target> Dell-BRIDGEMIBOBJECTS-MIB::rldot1sMstpInstanceTopChanges.1
