In TS-1000 MC loop back mode,
1 = Drop OAM frames and Ethernet frames with the following
errors – CRC, undersize, oversize. Loop back Ethernet frames
with only good CRC and valid length.
0 = Drop OAM frames only. Loop back all Ethernet frames
including those with errors.
Testing mode.
Set to ‘0’ for normal operation.
MCLBM1 MCLBM0 Loop back position
Note: If MCLBM0 is set to ‘1’, MCLBM1 is a “Don’t care”.
LED mode select
This bit and bit 7 of this register select the LED mode.
For LED definitions, see pins 1, 2, 3, 4, 5 and 6 of Pin
Description and I/O Assignment listing.
Notes:
Used for direct mode forwarding from port 3. See description
in spanning tree functional description.
0 = Disable
1 = Enable
