police aggregate
Use the police aggregate policy-map class configuration command to apply an aggregate policer to
multiple classes in the same policy map. A policer defines a maximum permissible rate of transmission,
a maximum burst size for transmissions, and an action to take if either maximum is exceeded. Use the
no form of this command to remove the specified policer.
police aggregate aggregate-policer-name
no police aggregate aggregate-policer-name
Syntax Description
Defaults No aggregate policers are defined.
Command Modes Policy-map class configuration
Command History
Usage Guidelines On standard ports and enhanced-services (ES) ports, the port ASIC device that controls the ports
supports 256 policers on the switch (255 user-configurable policers plus 1 policer reserved for system
internal use). The maximum number of policers that can be configured per port is 63. Policers are
allocated on demand by the software and are constrained by the hardware and ASIC boundaries. You
cannot reserve policers per port. There is no guarantee that a port will be assigned to any policer. These
limitations do not apply to policers configured in a hierarchical policy attached to an ES port.
You set aggregate policer parameters by using the mls qos aggregate-policer global configuration
command. You apply an aggregate policer to multiple classes in the same policy map; you cannot use an
aggregate policer across different policy maps.
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode,
use the end command.
In Cisco IOS Release 12.2(25)EY or later, you can configure aggregate policers only in nonhierarchical
single-level policy maps.
Examples This example shows how to define the aggregate policer parameters and to apply the policer to multiple
classes in a policy map:
Switch(config)# mls qos aggregate-policer agg_policer1 10000 1000000 exceed-action drop
Switch(config)# policy-map policy2
Switch(config-pmap)# class class1
Switch(config-pmap-c)# police aggregate agg_policer1
Switch(config-pmap-c)# exit
Switch(config-pmap)# class class2
Switch(config-pmap-c)# set ip dscp 10
aggregate-policer-name Name of the aggregate policer.
