Trigger the loopback test. The LBM packet is often compared to ping. A MEP transmits the loopback message to an intermediate or endpoint within a domain for the purpose of fault verification. This can be used to check the ability of the network to forward different sized frames.


Command Parameters

Specifies the remote MAC address to reach the MEP/MIP.
Specifies the MEP ID.
burst-count <1-200>
Specifies the burst count.
data-tlv-size <0-400>
Specifies the data Type-Length-Value (TLV) size.
frame-size <64-1500>
Specifies the frame size. The default is 0.
interframe-interval <0-1000>
Specifies the interval between LBM frames in msecs. A value of 0 msecs indicates to send the frames as fast as possible. The default is 500.
priority <0-7>
Specifies the priority. The default is 7.
source-mode {nodal | smltVirtual}
Specifies the source mode as nodal or smltVirtual. The default is nodal.
test-fill-pattern {all-zero|all-zero-crc|pseudo-random-bit-sequence|pseudo-random-bit-sequence-crc}
Specifies the testfill pattern: all-zero: null signal without cyclic redundancy check; all-zero-crc: null signal with cyclic redundancy check with 32-bit polynomial; pseudo-random-bit-sequence: PRBS without cyclic redundancy check; or pseudo-random-bit-sequence-crc: pseudo-random-bit-sequence with cyclic redundancy check with 32-bit polynomial. A cyclic redundancy check is a code that detects errors. The default is 1:all-zero.
time-out <1-10>
Specifies the time-out interval in seconds. The default is 3.
WORD<1-22> WORD<1-22>
The first parameter, specifies the Maintenance domain name. The second parameter, specifies the Maintenance association name.
