Configuring Traffic Shaping
Traffic shaping allows you to control the traffic exiting an interface to match its transmission to the speed
of the remote target interface and ensure that the traffic conforms to policies contracted for it.
Shaping performed on outgoing interfaces is done at the Layer 2 level and includes the Layer 2 header
in the rate calculation.
Step 7
exit
Example:
RP/0/RP0/CPU0:router(config-pmap)# exit
Returns the router to global configuration mode.
Step 8
interface type instance
Example:
RP/0/RP1/CPU0:router(config)# interface POS
0/2/0/0
Enters interface configuration mode, and configures an
interface.
Step 9
service-policy {input | output} policy-map
Example:
RP/0/RP0/CPU0:router(config-if)# service-policy
output voice
Attaches a policy map to an input interface or an output
interface to be used as the service policy for that interface.
• The traffic policy evaluates all traffic leaving that
interface.
Step 10
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-if)# end
or
RP/0/RP0/CPU0:router(config-if)# 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 11
show policy-map interface type instance [input
| output]
Example:
RP/0/RP0/CPU0:router# show policy-map interface
POS 0/2/0/0
(Optional) Displays policy configuration information for all
classes configured for all service policies on the specified
interface.
