service-instance instance-id: Specifies the service instance ID, ranging from 1 to 32767. 

mep mep-id: Specifies the ID of the MEP that sends LTMs, ranging from 1 to 8191. 

target-map target-mep-id: Specifies the ID of the MEP that receives LTM, ranging from 1 to 8191. 

target-mac mac-address: Specifies the destination MAC address, in the format of H-H-H. 

ttl ttl-value: Specifies the time to live value, ranging from 1 to 255 and defaulting to 64. 

hw-only: Indicates the hw-only position of the LTMs sent. When this keyword is present and the MIP 

that receives LTMs cannot find the destination MAC address in its forwarding table, the MIP will not 

forward these broadcast messages. Otherwise, the LTMs will be forwarded. 

Use the cfd linktrace command to find the path between the specified MEP and the destination MEP, 

which is achieved through the transmission of LTMs between the two and detection of the responding 

LTRs.
