The ForwarderEndpoints default polling group is used by MPLS Manager to monitor the availability of Forwarder endpoint connections. MPLS Manager monitors the availability by monitoring the ForwarderEndpoints that are discovered on PE devices.
The ForwarderEndpoints polling group has a default setting and an optional setting:
ForwarderEndpoint SNMP Setting (default)
ForwarderEndpoint External Setting (optional)
The two settings are mutually exclusive, meaning that only one or the other (but not both) can be specified for a ForwarderEndpoints polling group at any given time.
