Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Topology changes.
What is dot1dStpTopChanges?
This OID counts how many times the network bridge detected changes in network topology (like a link failure or recovery). It indicates how often the bridge has to recalculate which ports forward traffic. Frequent changes signal unstable network links or redundancy events that need investigation.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.2.4 snmpwalk -v2c -c public <target> BRIDGE-MIB::dot1dStpTopChanges
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.17.2.4.1 snmpget -v2c -c public <target> BRIDGE-MIB::dot1dStpTopChanges.1
