The IMA Link Status screen lists the following information pertaining to the IMA
status of an individual link in an IMA group.
NE Tx State —Near-end transmit state in the interworking link state machine.
Table 34 lists the possible link states.
NE Rx State —Near-end transmit state in the interworking link state machine.
Table 34 lists the possible link states.
FE Tx State —Far-end transmit state in the interworking link state machine.
Table 34 lists the possible link states.
FE Rx State —Far-end transmit state in the interworking link state machine.
Table 34 lists the possible link states.
.
FE Rx Failure —Far-end Rx failure status in the interworking link state machine.
Table 35 lists the possible IMA link failure status conditions.
NE Rx Failure —Near-end Rx failure status in the interworking link state machine.
Table 35 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.

State Tx Condition Rx Condition
not in group This link is not part of the IMA
group. This link is not part of the IMA
group.
unusable
blocked This is caused by LOS, which
would result in back clock from
the framer if the port is in
looped timing. This is caused by AFA,
excessive delay, or mismatched
protocol.
usable This link is ready to pass data. This link is ready to pass data.
active This link is passing data. This link is passing data.
Table 35 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.
