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 remains 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). Sets this to stop a
test once it exceeds the time duration without receiving
any response.

interface port-channel
port(s).
C
13
ethernet cfm virtual-mac <mac-
addr>
Assigns a virtual MAC address(es) to the specified
port(s) so that each specified port can have its own MAC
address for CFM.
C
13
no ethernet cfm virtual-mac
Removes the virtual MAC address(es) and sets the
port(s) to use the default system MAC address.
C
13
no ethernet cfm
Disables CFM on the Switch.
C
13
no ethernet cfm md <md-index>
Deletes the specified MD.
C
13
no ethernet cfm ma <ma-index> md
Deletes an MA from the specified MD.

show ethernet cfm local
Displays the detailed settings of the configured MD(s)
and MA(s).
E

show ethernet cfm local stack
Displays a list of all maintenance points, such as MIP
and MEP.

show ethernet cfm local stack mep
<mep-id> ma <ma-index> md <md-
index>
Displays the specified MEP’s general, fault notification
generator, continuity-check, loopback and link trace
information.

show ethernet cfm local stack mep
<mep-id> ma <ma-index> md <md-
index> mep-ccmdb [remote-mep <mep-
id>]
Displays the specified MEP’s MEP-CCM database
information. Each MEP maintains an MEP CCM
database which stores information about remote MEPs
in the MA when receiving CCMs.
E

show ethernet cfm local stack mip
Displays a list of the MIP(s).

Displays a list of MA(s), MEP(s) and the remote MEP(s)
under the configured MD(s).
