Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
This command can only be configured on full T1 or E1 channel groups; it is not supported on fractional, or
DS0 links.
The lnm remove command cannot be configured with the lnm major-warning command—they are mutually
exclusive.
The remove threshold values must be greater than the values configured in the lnm minor-warning command.
LNM supports hierarchical level alarm reporting as defined in the Telcordia (Bellcore) GR-253 standard.
Hierarchical alarm reporting means that whenever a higher alarm is asserted, the lower alarm state is suppressed.
When the high alarm is cleared, the lower alarm will re-assert if the condition still exists.
For LNM, this means that if a remove threshold is exceeded resulting in a crossed event and alarm state
reached, then a minor warning alarm state is suppressed and placed in stable state. The minor crossed event
also is removed from the bistate log. Only a single crossed event for major warnings will appear in the bistate
log for the controller. When the major warning is cleared, the minor warning alarm is asserted if the condition
still exists.

Examples The following example shows how to enable link noise monitoring to signal the noise attribute to PPP for
link removal on a T1 channel group using the default values for the set and clear threshold values of 1544
LCVs and 320 PCVs for a duration of 10 seconds:
RP/0/RSP0/CPU0:router(config)# controller t1 0/6/0/0/1/1
RP/0/RSP0/CPU0:router(config-t1)# lnm remove
The following example shows how to specify set and clear thresholds for link noise monitoring on an E1
channel group to signal the noise attribute to PPP for link removal:
RP/0/RSP0/CPU0:router(config)# controller e1 0/3/0/0/0/1
