Priority
The priority to be inserted as PCP bits in TAG (if any). In case of enable of Continuity
Check and Loss Measurement both implemented on SW based CCM, 'Priority' has to
be the same.
Cast
Selection of LM PDU transmitted unicast or multicast. The unicast MAC will be taken
from the 'Unicast Peer MAC' database. In case of enable of Continuity Check and dual
ended Loss Measurement both implemented on SW based CCM, 'Cast' has to be the
same.
Peer MEP
Peer MEP-ID for unicast LM. The MAC is taken from the 'Unicast Peer MAC' database.
Only used in case of multiple peers ('Synthetic' LM).
Rate
Selecting the frame rate of LM PDU. This is the inverse of transmission period as
described in Y.1731
Selecting 100f/sec is only valid in case of 'Synthetic' LM.
Selecting 6f/min is not valid in case of dual ended 'Service frame' LM (CCM PDU
based).
In case of enable of Continuity Check and Loss Measurement both implemented on
SW based CCM, 'Frame Rate' has to be the same.
Size
The 'Synthetic' SLM/1SL frame size. This is entered as the wanted size (in bytes) of a
un-tagged frame containing LM OAM PDU - including CRC (four bytes).
Example when 'Size' = 64 => Un-tagged frame size = DMAC(6) + SMAC(6) + TYPE(2)
+ LBM PDU LENGTH(46) + CRC(4) = 64 bytes
The transmitted frame will be four bytes longer for each tag added - 8 bytes in case of
a tunnel EVC.
There are two frame MAX sizes to consider.
Switch RX frame MAX size: The MAX frame size (all inclusive) accepted on the switch
port of Bytes
CPU RX frame MAX size: The MAX frame size (all inclusive) possible to copy to CPU
of Bytes
Consider that the Peer MEP must be able to handle the selected frame size. Consider
that the received SLR PDU must be copied to CPU
Warning will be given if selected frame size exceeds the CPU RX frame MAX size
