Configuring a Clear Channel SONET Controller for T3
This task explains how to configure a SONET line into a single T3 serial channel called clear channel.
Clear channel is established by setting the T3 controller mode to serial.
Prerequisites
• You should know how to configure the SONET controller as specified in the “How to Configure
Clear Channel SONET Controllers” section of the Configuring Clear Channel SONET Controllers
on the Cisco ASR 9000 Series Router module.
SUMMARY STEPS
1. configure
2. controller sonet interface-path-id
3. clock source {internal | line}
Step 13
no shutdown
Example:
RP/0/RSP0/CPU0:router (config-if)# no
shutdown
Removes the shutdown configuration.
Note Removal of the shutdown configuration eliminates the
forced administrative down on the interface, enabling it to
move to an up or down state (assuming that the parent
SONET layer is not configured administratively down).
Step 14
end
or
commit
Example:
RP/0/RSP0/CPU0:router(config-sonet)# end
or
RP/0/RSP0/CPU0:router(config-sonet)#
commit
Saves configuration changes.
• When you issue the end command, the system prompts you to
commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the running
configuration file, exits the configuration session, and
returns the router to EXEC mode.
–
Entering no exits the configuration session and returns the
router to EXEC mode without committing the
configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or committing the
configuration changes.
• Use the commit command to save the configuration changes to
the running configuration file and remain within the
configuration session.
Step 15
show interfaces pos interface-path-id
Example:
RP/0/0/CPU0:router# show interfaces pos
0/1/1/0
(Optional) Displays the interface configuration.
