Alarm Meaning
Group [n] Dup. IMA The same group IMA ID has
ID been received on links

groups in the same card.
Group [n] FE Abort The far end rejects the

Abort used by the near end.

Insufficient Links an insufficient number of links.
ATM Forum (R-131)
Group [n] The near end finds not enough
Insufficient Links available links.
ATM Forum (R-130) This occurs when the near end
has completed parameter
negotiation with the far end,
but is neither passing data nor
blocked.
Group [n] Lack of The near end is idling because
Link it does not have enough links
in an IMA group. This occurs
only after group parameters
are negotiated. When this
occurs, the "NE Insufficient

Managing System Alarms
Troubleshooting Steps
Correct link or group configuration.
Check and correct near end symmetry.
Only symmetric operation is supported
in PathBuilder products.
Check and repair link facilities. Verify
configuration.
Configure both ends to the same M
value.
NOTE: This alarm should not occur if
both ends are PathBuilder S310, S330,
S600, or S700 products.
Information about far end state.
Check and repair link facilities. Verify
configuration.
Check and correct any faulty IMA links.
Check and correct IMA minimum links
parameter.
Take the group down, and stop passing
data in all links.
Information only.
Information only.
Continue passing data.
If one or more links comes back,
re-identify the link(s) and renegotiate
parameters with the far end group.
