BAD SCCI
(3Com Patent
Pending) Status and Change Control
Indication – the content of the
ICP cells has changed. The far
end ICP cell SCCI in this link
does not agree with the SCCI
of the other links in the group. Check the links for proper connection.
Reconnect if necessary.
Bad Symmetry The far end group symmetry
has changed in an IMA link. Remove the link and stop Tx and Rx
data.
Duplicated IMA ID An IMA group has received an
IMA ID that has been received
by a previous group. The
second group must have a
unique IMA ID. Check for loops and check the IMA
group configuration.
Duplicated Link ID Duplicated far end logical link
ID in this IMA group for this
IMA link.
Each IMA group assigns a
unique Transmit link ID to each
link in the group. This link ID
should match the Receive link
ID of the remote end IMA
device. This alarm means that a
link received a Transmit link ID
already assigned to a previous
link.
Check the links for proper connection.
Reconnect if necessary.
Duplicated Offset Duplicated far end ICP cell
offset in this IMA group in an
IMA link.
Each IMA group assigns a
unique Transmit offset to each
link in the group. This alarm
means that a link received a
Transmit offset already
assigned to a previous link.
Some of the links are probably
misconnected.
Check the links for proper connection.
Reconnect if necessary.
Excessive Link Delay The link has exceeded the
user-selectable value for
acceptable link delay.
The link is removed from the
group.
Check the links for proper connection.
Reconnect if necessary. Also try
adjusting the link delay parameter for
the IMA group.

Config. Abort is generated,
due to group symmetry
problem
Check and correct near end symmetry.
Only symmetric operation is supported
in PathBuilder products.
Group [n] Config
Abort
ATM Forum (R-128)
The near end node rejects the
far end IMA parameters. Check and correct the near end and far
end parameters for compatibility.
Group [n] Degraded
Service The IMA group is passing data
with less than the number of
IMA links you configured. Continue passing data. Correct faulty
links or adjust IMA group
configuration.
