The BGP Protocol Endpoints default threshold group is used by Network Protocol Manager for BGP to configure parameters for flapping analysis of BGP protocol endpoints. (A flapping endpoint is an endpoint that is continually going up and down.) Flapping analysis monitors SNMP bgpEstablished traps to identify a flapping endpoint, and then generates a Flapping event for the associated BGP session to report that the endpoint is flapping.
The Network Protocol Manager for BGP User Guide provides information about how the Network Protocol Manager for BGP determines that a BGP protocol endpoint is flapping.
