About Link Noise Monitoring
Enabling Syslog Messages
To enable the generation of syslog messages on a particular T1/TE1 link use the following command
syntax. Use the no form of the command to disable generation of syslog messages.
Command Description
Step 1 t1 t1-number channel-group
channel-group-number timeslots
list-of-timeslots
Example:
Router(config-controller)# t1 1
channel-group 0 timeslots 1-24
Specifies the channel group and timeslots on a T1 interface.
• t1-number—The T1 interface number from 1 to 28.
• Channel-group channel-group-number—Identifies the
channel group with any number from 0 to 23
• Timeslots list-of-timeslots—T1 is divided into 24 timeslots
(or DS0s).
Step 2 t1 t1-number span {minor-warn | {remove |
major-warn}} [{[lcv value [pcv value]]
[duration seconds]} set | clear]
Example:
Router(config-controller)# t1 1 span
minor-warn lcv 20 pcv 10 duration 10 set
Generates a minor-warn, a major-warn or a remove event based
on the defined thresholds, for the T1 interface.
• t1-number—The T1 interface number from 1 to 28.
• minor-warn—Enables link warning (minor) monitoring
on the link.
• major-warn—Enables link warning (major) monitoring on
the link.
• remove—Enables Link Removal monitoring on the link.
• lcv value—The Line Code Violation (LCV) threshold value
in bit error per second. The valid range on a T1 link is 5 to
1544 seconds. The valid range on an E1 link is 7 to 2048
seconds.
– The default LCV value for minor-warn on a T1 link is
154 seconds and an E1 link is 205 seconds.
– The default LCV value for major-warn or removal on a
TI link is 1544 seconds and an E1 link is 2048 seconds.
• pcv value—Number of time slots in error per second. If not
specified, this value is calculated from the LCV threshold
based on a Gaussian distribution.
– The default PCV value for minor-warn on a T1 link is
145 seconds and an E1 link is 205 seconds.
– The default PCV value for major-warn or removal on a
TI link is 320 seconds and an E1 link is 832 seconds.
• duration seconds—The number of consecutive seconds
that a threshold is exceeded or improved for a condition to
occur. The valid range on a T1/E1 link is 4 to 600 seconds.
The default value for T1 and E1 links is 10 seconds.
• set—Specifies the set condition. Set is the default when no
conditions are specified.
• clear— Specifies the clear condition.
