Managing System Alarms 215
Group [n] Dup. IMA
ID The same group IMA ID has
been received on links
belonging to different IMA
groups in the same card. Correct link or group configuration.
Group [n] FE Abort
Symmetry The far end rejects the
symmetry sent by the near end. Check and correct near end symmetry.
Only symmetric operation is supported
in PathBuilder products.
Group [n] FE
Blocked
ATM Forum (R-132)
The far end reports it is not
passing data. Check and repair link facilities. Verify
configuration.
Group [n] FE Config
Abort The far end rejects the M value
used by the near end. 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.
Group [n] FE Start
Up
ATM Forum (R-127)
The far end is coming up
(starting IMA). Information about far end state.
Group [n] FE
Insufficient Links
ATM Forum (R-131)
The far end node is reporting
an insufficient number of links. Check and repair link facilities. Verify
configuration.
Group [n]
Insufficient Links
ATM Forum (R-130)
The near end finds not enough
available links.
This occurs when the near end
has completed parameter
negotiation with the far end,
but is neither passing data nor
blocked.
Check and correct any faulty IMA links.
Check and correct IMA minimum links
parameter.
Group [n] Lack of
Link The near end is idling because
it does not have enough links
in an IMA group. This occurs
only after group parameters
are negotiated. When this
occurs, the “NE Insufficient
Links” alarm is also reported. Take the group down, and stop passing
data in all links.
Group [n] Link
Down Summary information alarm to
indicate one or more alarms on
this IMA group are active. Information only.
Group [n] Link Up Summary informational alarm
to indicate all alarms on the
IMA group are cleared. Information only.
Group [n] N<P There are fewer configured
links than IMA links required to
make an IMA group active. Continue passing data.
Group [n] No Link The near end has lost all its
links in an IMA group because
these links have AFA, LOS, AIS,
OOF, LCD, or missing ICP cells.
This invalidates all the far end
identity. If one or more links comes back,
re-identify the link(s) and renegotiate
parameters with the far end group.
