This example shows the default policers assigned to NNIs. Most protocols have no policers assigned to
NNIs. A value of 255 means that no policer is assigned to the port for the protocol.

Configuring Control-Plane Security
CPU protection is enabled by default and CPU policers are pre-allocated. You can disable CPU
protection by entering the no policer cpu uni all global configuration command or reenable it by
entering the policer cpu uni all global configuration command. When you disable or enable CPU
protection, you must reload the switch by entering the reload privileged EXEC command before the
configuration takes effect.
When CPU protection is enabled, you can configure only 45 policers per port. Disabling CPU protection
allows you to configure up to 64 policers per port. Note these limitations when you disable CPU
protection:

When CPU protection is disabled, you can configure a maximum of 63 policers per port (62 on every
4th port) for user-defined classes and one for class-default.
On Cisco ME 3400G-12CS switches, due to hardware limitations, you can attach 64 per-port,
per-VLAN policers to a maximum of 6 ports. If you attempt to attach more than 6 per-port per
VLAN 64-policer policy maps, the attachment fails with a VLAN labels exceeded error message.
