Parameters
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.
Description
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.
