FE Rx Failure
— Far-end Rx failure status in the interworking link state machine.
Table 7 lists the possible IMA link failure status conditions.
Tx LID
— Transmit logical link ID:
0-31
. This number reflects the local IMA ID.
Rx LID
— Receive logical link ID:
0-31
. This number reflects the remote IMA ID.
Operation Link Delay
— The differential link delay referenced to the fastest link
in the same group.
Rx Test Pattern
— The received test pattern received:
0-254
;
255
indicates that
no pattern has been received.
Test Procedure
— The status of the test procedure:
disabled
,
operating
, or
link
failed
.

Possible IMA LInk Failure Status Conditions
Failure
Description
link failure
This is caused by LOS, AIS, OOF, or LCD.
LIF failure
This is caused by LIF.
LODS failure
This is caused by LODS.
Misconnected
This is caused by bad IMA ID, bad link ID, or bad SCCI.
blocked
This is caused by AFA, excessive delay, or mismatched protocol.
fault
This is caused by bad M value, bad symmetry, bad offset, or
duplicate link ID.
far end Tx link unusable
This is caused by the far end reporting Tx unusable in the ICP
cells.
far end Rx link unusable
This is caused by the far end reporting Rx unusable in the ICP
cells.
no failure
The link has no failure.
