[Sysname] cfd enable
cfd linktrace
Use cfd linktrace to find the path between the source and target MEPs, 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-mep target-mep-id | target-mac
mac-address } [ 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-map target-mep-id: Specifies the ID of the destination MEP, in the range of 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 in the range of 1 to 255. The default is 64.
hw-only: Sets the hw-only bits of the LTMs sent. When this keyword is specified and the MIP that receives
LTMs cannot find the destination MAC address in its forwarding table, the MIP does not broadcast these
LTM messages. Otherwise, the MIP broadcasts these LTM messages.
