Description

DIFF_DELAY_INT
Differential Delay is out of bounds on
link addition/or recovery. This indicates
the delay on the link was out of bounds
of the programmed differential delay
and that the link failed to come up for
this reason.

21
LODS_OVERRUN_I LODS, DCB overrun. An overrun
NT condition occurred.
LODS_UNDERRUN_ LODS, DCB underrun. Indicates that
INT
the DCB buffer experienced an
underrun condition and has disabled
itself from forwarding traffic to the ATM
layer. An underrun occurs when the
transport delay for the link is detected
to be outside the programmed limit and
the transport delay is smaller than the
other links within the group In general,
this will happen only if the transport
delay of the link changes. An underrun
condition requires that the link delay be
revalidated prior to being placed back
in service.

LCD_INT
A change of state of the LCD status bit
was detected.
A change of state of the LIF status bit
was detected.
Invalid ICP parameters detected on RX
link during validation of the ICP cell
parameters causing validation to fail.
Possible reasons include:
LIF_INT
INVALID_ICP _INT
Invalid LID (i.e., a duplicate).
Invalid ICP cell offset (out of range).
Invalid RX IMA ID, which may indicate
a misconnectivity problem.
Invalid OAM label received after IMA
