Description:
What is accStpTopChangeCnts?
This counter tracks the total number of spanning tree topology changes that have occurred (when a port transitions between spanning tree states or a link failure triggers recalculation). Engineers watch this metric closely because frequent topology changes indicate network instability, flapping links, or misconfigured priorities that cause repeated rebalancing. A counter incrementing from 0 to 10 within a single hour suggests the network is experiencing repeated disruptions requiring investigation into which ports are becoming unstable.
Examples
Walk all instances (SNMPv2c):

Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.2.17.1 snmpget -v2c -c public <target> ACC-MIB::accStpTopChangeCnts.1
