Use the mls qos aggregate-policer global configuration command on the switch stack or on a standalone
switch to define policer parameters, which can be shared by multiple classes within 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 delete an
aggregate policer.

Global configuration
Release Modification
12.2(53)SE2 This command was introduced.
Define an aggregate policer if the policer is shared with multiple classes.
Policers for a port cannot be shared with other policers for another port; traffic from two different ports
cannot be aggregated for policing purposes.
The port ASIC device, which controls more than one physical port, supports 256 policers on the switch
(255 user-configurable policers plus 1 policer reserved for internal use). The maximum number of
configurable policers supported 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).
You apply an aggregate policer to multiple classes in the same policy map; you cannot use an aggregate
policer across different policy maps.

Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands
Name of the aggregate policer referenced by the police aggregate
policy-map class configuration command.
Specify the average traffic rate in bits per second (b/s). The range
is 8000 to 1000000000.
Specify the normal burst size in bytes. The range is 8000 to 1000000.
When the specified rate is exceeded, specify that the switch drop the
packet.
When the specified rate is exceeded, specify that the switch change the
Differentiated Services Code Point (DSCP) of the packet to that
specified in the policed-DSCP map and then send the packet.
