Context oam
Description
This command enables the context to configure LDP treetrace parameters to perform Alcatel-Lucent
OAM tree trace test operations manually.
Parameters
prefix ip-prefix/mask — Specifies the address prefix and subnet mask of the destination node.
max-ttl max-label-ttl — The maximum TTL value in the MPLS label for the LSP trace test,
max-paths max-paths — The maximum number of paths for a ldp-treetrace test, expressed as a

used to override the default timeout value and is the amount of time that the router will wait for a
message reply after sending the message request. Upon the expiration of message timeout, the
requesting router assumes that the message response will not be received. Any response received
after the request times out will be silently discarded.

echo request 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.
