ethernet cfm linktrace mac < mac-
address > mep < mep-id > ma < ma-index >
md < md-index > [ mip-ccmdb ][[ttl
< ttl >]
Specifies the destination MAC address, local
MEP ID, MA index and MD index to perform a link
trace test.
This enables the MEP port (with the specified
MEP ID) in a specified CFM domain to send the
LTMs (Link Trace Messages) to a specified
remote end point.
mip-ccmdb
:
Specifies the MIP CCM DB, a
database that stores information (tuples of {Port,
VID, MAC address}) about MEPs in the MD when
receiving CCMs. The MIP CCM DB is used for
fault isolation, such as link trace and loop back.
An entry can remain in the MIP CCM DB for at
least 24 hours.
ttl
: This is the time-to-live value (the number of
transmissions, 64 hops by default). Set this to stop
a test once it exceeds the time duration without
receiving any response.

ethernet cfm linktrace remote-mep
< mep-id > mep < mep-id > ma < ma-index >
md < md-index > [ mip-ccmdb ][[ttl
< ttl >]
Specifies the remote MEP ID, local MEP ID, MA
index and MD index to perform a link trace test.
This enables the MEP port (with the specified
MEP ID) in a specified CFM domain to send the
LTMs (Link Trace Messages) to a specified
remote end point.

database that stores information (tuples of {Port,

a test once it exceeds the time duration without
receiving any response.

ethernet cfm loopback mac < mac-
address > mep < mep-id > ma < ma-index >
md < md-index > [size <0-
1500>][count <1-1024>]
Specifies the destination MAC address, local
MEP ID, MA index and MD index to perform a
loopback test.
This enables the MEP port (with the specified
MEP ID) in a specified CFM domain to send the
LBMs (Loop Back Messages) to a specified
remote end point.
You can also define the packet size (from 0 to
1500 bytes) and how many times the OLT sends
the LBMs.
