cfd linktrace

Use cfd linktrace to find the path between the source MEP and target MP, which is achieved through the
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.
ttl ttl-value: Specifies the time to live value in the range of 1 to 255. The default is 64.
hw-only: Sets the hw-only bits of the LTMs sent. If this keyword is specified, the MIP does not flood LTM
messages that have an unknown destination MAC address.
