transmission of LTMs between the two and detection of the responding LTRs.
Syntax
cfd linktrace service-instance instance-id mep mep-id { target-mac mac-address | target-mep
target-mep-id } [ ttl ttl-value ] [ hw-only ]

Parameters
service-instance instance-id: Specifies the service instance ID in the range of 1 to 32767.
mep mep-id: Specifies the ID of the source MEP, in the range of 1 to 8191.
target-mac mac-address: Specifies the destination MAC address, in the format of H-H-H.
target-map target-mep-id: Specifies the ID of the destination MEP, in the range of 1 to 8191.
