Prerequisites for Ethernet Data Plane Loopback
•
Ethernet loopback sessions are supported only of EFPs (service instances, Ethernet flow points, EVCs).
•
Internal loopback sessions configured must be within the 1 GB reserved bandwidth.
•
Internal loopback can be launched even when the physical interface port state is down.
Restrictions for Ethernet Data Plane Loopback
•
Data plane loopback on routed port infrastructure is not supported.
•
Etype, src-mac, and llc-oui based loopback traffic filtering is not supported.
•
Port-level QoS is not bypassed.
•
Port shaper cannot be bypassed in facility loopback.
•
Facility and terminal Ethernet data plane loopback (ELB) are not supported on dot1ad nni interface.
•
Internal loopback sessions configured must be within the 1 GB reserved bandwidth for Cisco ASR 900
Series RSP2 Module.
