shows how to configure the LNM feature ona 2-port Channelized OC12/DS0 SPA.
Example 2
Sample Output of LNM Configuration on a SPA
Router# configure terminal
Router(config)# controller soNET 5/1/0
Router(config-controller)# framing sonet
Router(config-controller)# clock source internal
Router(config-controller)# sts-1 1
Router (config-ctrlr-sts1)# mode ct3
Router (config-ctrlr-sts1)# t1 1 channel-group 0 timeslots 1-24
! Once a T1/E1 is created, LNM can be configured using 'span' CLI
Router (config-ctrlr-sts1)# t1 1 ?
channel-group Specify the timeslots to channel-group mapping for an 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
shutdown Shut down a T1 interface (send AIS)
span Noise monitor for managing noisy T1 spans <Ð=
yellow Yellow Alarm Configuration for a T1
Example of a Syslog Message
The following is a sample output of a generated fault notification on a serial interface:
LNM-3- MINWARNEXCEED: Interface Serial7/0/0.1/1:0, noise exceeded above minor warning
threshold
.
Verification Example for Link Noise Monitoring
shows the sample output when the LNM feature is configured. Use the show controllers t3
command to view the configuration information.
