Usage Guidelines
Define an aggregate policer if the policer is shared with multiple classes.
Policers in one port cannot be shared with other policers in another port; traffic from two different ports
cannot be aggregated for policing purposes.
You cannot attach an aggregate policer to the ingress or egress of the same port.
Although the command-line help strings show a large range of values, the rate-bps option cannot exceed
the configured port speed. If you enter a larger value, the switch rejects the policy map when you attach
it to an interface.
You apply an aggregate policer to multiple classes in the same policy map; you cannot use an aggregate
policer across different policy maps or interfaces.

The ranges for rate-bps and burst-bps was changed.
Name of the aggregate policer referenced by the police aggregate
policy-map class configuration command.
Specify average traffic rate in bits per second (bps). The range is 8000
to 1000000000.
Specify the normal burst size in bytes. The range is 8000 to 2000000.
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
