[BFM #1100 to #1267] Pre-defined Layer 2 Messages Parameter

This section describes the Pre-defined Layer 2 messages configuration.
The Layer 2 message parameter defines if the corresponding Layer 2 message in BFM #100 to #393 is a
transmit or receive message, e.g. Layer 2 message parameter 2 (BFM #1104 to #1107) determines the
function of Layer 2 message 2 (BFM #107 to #113).
Note
• The Pre-defined Layer 2 messages configuration can be set in offline mode (set BFM #25 bit 4 OFF and
wait for BFM #25 bit 0 OFF).
• If an invalid value is written to one of BFM #1100 to #1267, then BFM #29 bit 6 is set, and the BFM address
is displayed in BFM #39.
• Set parameter A and B of unused Layer 2 messages to HFFFF.
