Configuration Examples for Link Noise Monitoring
This section provides the following configuration examples:
• Example of LNM Configuration on a Line Card, page 17-4
• Example of LNM Configuration on a Shared Port Adapter, page 17-5
• Example of a Syslog Message, page 17-5
Example of LNM Configuration on a Line Card
Example 1 shows how to configure the LNM feature on the 4-port Channelized OC-3/STM-1 and 1-port
Channelized OC-12 line cards.
Example 1 Sample Output of LNM Configuration on a Line Card
Router# configure terminal
Router(config)# controller soNET 7/0/0
Router(config-controller)# framing sonet
Router(config-controller)# clock source internal
Router(config-controller)# path 1 controller t3
Router(config-controller)# exit
Router(config)# controller t3 7/0/0.1
Router(config-controller)# t1 1 channel-group 0 timeslots 1-24
! Once a T1/E1 is created, LNM can be configured using 'span' CLI
Router(config-controller)# t1 1 ?
bert Start BERT test
channel-group Specify a channel-group mapping on a T1 interface
clock Specify the clock source for a T1
fdl Specify the Facility Data Link for a T1
framing Specify the type of Framing on a T1
loopback Put the T1 line into loopback
span Noise monitor for managing noisy T1 spans
Router(config-controller)# t1 1 span
Command Description
Step 1 Router# t1 <1-28> span syslog
Router# e1 <1-21> span syslog
Example:
Router# t1 3 span syslog
Generates syslog messages for the specified T1 link. A T1 link
has 28 channels. An E1 link has 21 channels.
Step 2 Router# no [e1 <1-21> span syslog]
Router# no [t1 <1-21> span syslog]
Example:
Router# no e1 3 span syslog
Disables generation of syslog messages for the specified
T1/E1link.
