Module: CTATX-MIB
OID (symbolic): CTATX-MIB::stTopChange

Description: Whether a topology change is currently in progress.
What is stTopChange?
This read-only INTEGER (true(1)/false(2)) reports whether a spanning tree topology change is currently in progress. An administrator polls this live flag to catch a transient reconvergence event as it is happening, rather than relying only on the cumulative stTopChangeCount. For example, the admin polls stTopChange while investigating a suspected flapping link and sees it toggle to true(1) at exactly the moment the flapping occurs.
