OAM and SAA Command Reference
fc fc-name — The fc parameter is used to indicate the forwarding class of the MPLS echo request
fc-name — The forwarding class of the MPLS echo request encapsulation.

Description
The mac-ping utility is used to determine the existence of an egress SAP binding of a given MAC
within a VPLS service.
A mac-ping packet can be sent via the control plane or the data plane. The send-control option
specifies the request be sent using the control plane. If send-control is not specified, the request is
sent using the data plane.
A mac-ping is forwarded along the flooding domain if no MAC address bindings exist. If MAC
address bindings exist, then the packet is forwarded along those paths, provided they are active. A
response is generated only when there is an egress SAP binding for that MAC address or if the MAC
address is a "local" OAM MAC address associated with the device's control plan.
A mac-ping reply can be sent using the data plane or the control plane. The return-control option
specifies the reply be sent using the control plane. If return-control is not specified, the request is
sent using the data plane.

If the interval is set to 1 second, and the timeout value is set to 10 seconds, then the maximum
time between message requests is 10 seconds and the minimum is 1 second. This depends upon
the receipt of a message reply corresponding to the outstanding message request.
Default
1
Values
1 — 10
packets. The actual forwarding class encoding is controlled by the network egress LSP-EXP
mappings.
The LSP-EXP mappings on the receive network interface controls the mapping back to the
internal forwarding class used by the far-end 7750 SR that receives the message request. The
egress mappings of the egress network interface on the far-end 7750 SR controls the forwarding
class markings on the return reply message.
The LSP-EXP mappings on the receive network interface controls the mapping of the message
reply back at the originating 7750 SR.
