Parameters orig-sdp-id — The SDP-ID to be used by sdp-ping, expressed as a decimal integer. The far-end
address of the specified SDP-ID is the expected responder-id within each reply received. The
specified SDP-ID defines the encapsulation of the SDP tunnel encapsulation used to reach the far
end. This can be IP/GRE or MPLS. If orig-sdp-id is invalid or administratively down or
unavailable for some reason, the SDP Echo Request message is not sent and an appropriate error
message is displayed (once the interval timer expires, sdp-ping will attempt to send the next
request if required).
Values 1 — 17407
resp-sdp resp-sdp-id — Optional parameter is used to specify the return SDP-ID to be used by the
far-end 7750 SR for the message reply for round trip SDP connectivity testing. If resp-sdp-id
does not exist on the far-end 7750 SR, terminates on another 7750 SR different than the
originating 7750 SR, or another issue prevents the far-end 7750 SR from using resp-sdp-id, the
SDP Echo Reply will be sent using generic IP/GRE OAM encapsulaton. The received
forwarding class (as mapped on the ingress network interface for the far end) defines the
forwarding class encapsulation for the reply message.
Default null. Use the non-SDP return path for message reply.
Values 1 — 17407
fc fc-name — The fc parameter is used to indicate the forwarding class of the SDP encapsulation.
The actual forwarding class encoding is controlled by the network egress DSCP or LSP-EXP
mappings.
The DSCP or 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 DSCP or LSP-EXP mappings on the receive network interface controls the mapping of the
message reply back at the originating 7750 SR. This is displayed in the response message output
upon receipt of the message reply.
