Parameters
service-instance
instance-id
: Specifies the service instance ID, ranging from 1 to 32767.
mep
mep-id
: Specifies the ID of the source MEP, ranging from 1 to 8191.
target-map
target-mep-id
: Specifies the ID of the destination MEP, ranging from 1 to 8191.
target-mac
mac-address
: Specifies the MAC address of the destination MP, 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
: 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 forwards these LTM messages.
Description
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.
