What is hgmpNTDPTOPTableChange?
This counter (0-65535) increments when the topology relationship table changes, signaling link additions or removals in the cluster. Engineers monitor this to detect cluster topology changes and avoid redundant table queries. An increment from 3 to 4 indicates one new inter-switch link was discovered.
