Purpose
(Optional) Specifies how to allocate leftover bandwidth to
various classes.
• The remaining bandwidth of 70 percent is shared by all
configured classes.
• In this example, class class1 receives 20 percent of the
70 percent.
(Optional) Shapes traffic to the specified bit rate or a
percentage of the available bandwidth.
Returns the router to global configuration mode.
Enters configuration mode and configures an interface.
Attaches a policy map to an input or output interface to be
used as the service policy for that interface.
In this example, the traffic policy evaluates all traffic
•
leaving that interface.
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.
