Cisco ASR 9000 Aggregation Services Router Interfaces and Hardware Component Configuration Guide
Purpose
Enters global configuration mode.
Enters serial subinterface configuration mode.
Enters subinterface configuration mode for the PVC.
(Optional) Configures the encapsulation for a Frame Relay
PVC.
If the encapsulation type is not configured explicitly
Note
for a PVC, then that PVC inherits the encapsulation
type from the main serial interface.
Attaches a policy map to an input subinterface or output
subinterface. Once attached, the policy map is used as the
service policy for the subinterface.
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.
