The following guidelines apply to two-color policing of Layer 2 traffic:
You can apply a two-color policer to ingress or egress Layer 2 traffic at a logical interface
hosted on a Gigabit Ethernet interface (
only.
A single logical interface supports Layer 2 policing in both directions.
You can apply a two-color policer to Layer 2 traffic as a logical interface policer only.
You cannot apply a two-color policer to Layer 2 traffic as a stateless firewall filter
action.
You can apply a two-color policer to Layer 2 traffic by referencing the policer in the
interface configuration at the logical unit level, and not at the protocol level.
For information about configuring three-color policing of Layer 2 traffic, see
