Configuring Policing
DETAILED STEPS
Command or Action
Step 1
configure terminal
Example:
switch# configure terminal
switch(config)#
Step 2 policy-map [type qos] [match-first]
[policy-map-name]
Example:
switch(config)# policy-map policy1
switch(config-pmap-qos)#
Step 3 class [type qos] {class-name | class-default}
[insert-before before-class-name]
Example:
switch(config-pmap-qos)# class class-default
switch(config-pmap-c-qos)#
Step 4 police [cir] {committed-rate [data-rate] | percent
cir-link-percent} [[bc | burst] burst-rate
[link-speed]] [[be | peak-burst] peak-burst-rate
[link-speed]] [conform conform-action [exceed
[violate drop set dscp dscp table
pir-markdown-map]]}
Step 5 exit
Example:
switch(config-pmap-c-qos)# exit
switch(config-pmap-qos)#
Step 6
exit
Example:
switch(config-pmap-qos)# exit
switch(config)#
Step 7
show policy-map [type qos] [policy-map-name]
Example:
switch(config)# show policy-map
Step 8
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
Purpose
Enters global configuration mode.
Creates or accesses the policy map named policy-map-name and
then enters policy-map mode. The policy-map name can contain
alphabetic, hyphen, or underscore characters, is case sensitive, and
can be up to 40 characters.
Creates a reference to class-name and enters policy-map class
configuration mode. The class is added to the end of the policy map
unless insert-before is used to specify the class to insert before.
Use the class-default keyword to select all traffic that is not
currently matched by classes in the policy map.
Polices cir in bits or as a percentage of the link rate. The conform
action is taken if the data rate is <= cir. If be and pir are not
specified, all other traffic takes the violate action. If be or violate
are specified, the exceed action is taken if the data rate <= pir, and
the violate action is taken otherwise. The actions are described in
the Policer Actions for Exceed or Violate table and the Policer
Actions for Conform table. The data rates and link speeds are
described in the Data Rates for the police Command table and the
Burst Sizes for the police Command table.
Exits policy-map class configuration mode and enters policy-map
mode.
Exits policy-map mode and enters global configuration mode.
(Optional) Displays information about all configured policy maps
or a selected policy map of type qos.
(Optional) Saves the running configuration to the startup
configuration.
