DESCRIPTION
Specifies the remote MEP ID, 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 Switch sends the
LBMs.
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 Switch sends the
LBMs.
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.
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.
Specifies the destination MAC address, local MEP ID,
MA index and MD index to perform a link trace test.
