If the
lnm major-warning
command is run and only the
set
option is configured, the threshold values defined
for the
set
option are also used as the
clear
threshold values. Alternatively, if the
lnm major-warning
command
is run and only the
clear
option is configured, the threshold values defined for the
clear
option are also used
as the
set
threshold values.

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 major-warning
command cannot be configured with the
lnm remove
command
—
they are mutually
exclusive.
The major 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 major warning 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 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 major-warning
The following example shows how to specify set and clear thresholds on an E1 channel group:
RP/0/RSP0/CPU0:router(config)#
controller e1 0/3/0/0/0/1
RP/0/RSP0/CPU0:router(config-e1)#
lnm major-warning set line-code-violation 1500
path-code-violation 100 duration 30
