vStpInsTopChanges
Module: ALCATEL-IND1-VLAN-STP-MIB
OID (symbolic): ALCATEL-IND1-VLAN-STP-MIB::vStpInsTopChanges
OID (numeric): 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.7
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The total number of topology changes detected by this spanning tree instance since the management entity was last reset or initialized.
What is vStpInsTopChanges?
This read-only counter tallies every topology change event (link failure or port role change) since the device booted. Network engineers use spike analysis to identify flaky links or unstable switch neighbors causing repeated STP recomputation. A rapidly increasing count suggests link instability or spanning tree loops.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.7 snmpwalk -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsTopChanges
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6486.801.1.2.1.12.1.1.1.1.1.7.1 snmpget -v2c -c public <target> ALCATEL-IND1-VLAN-STP-MIB::vStpInsTopChanges.1
