out-of-profile packets that are either in excess of the conformance specification or
are non-conformant.

The DiffServ feature supports the following types of traffic policing treatments
(actions):

-

Send: The packet is forwarded without DiffServ modification.

-

Drop: The packet is dropped.

-

Mark CoS: The 802.1p user priority bits are (re)marked and forwarded.

-

Mark DSCP: The packet DSCP is (re)marked and forwarded.

-

Mark IP precedence: The packet IP Precedence is (re)marked and forwarded.

Color mode awareness: Policing in the DiffServ feature uses either

color blind

or

color aware

mode. Color blind mode ignores the coloration (marking) of the incoming

packet. Color aware mode takes into consideration the current packet marking when
determining the policing outcome. An auxiliary traffic class is used in conjunction
with the policing definition to specify a value for one of the 802.1p, secondary 802.1p,
IP DSCP, or IP Precedence fields designating the incoming color value to be used
as the conforming color. As an option, you can also specify the color of exceeding
traffic.

Assigning QoS queue: Directs a traffic stream to the specified QoS queue. This
allows a traffic classifier to specify which one of the supported hardware queues is
used for handling packets belonging to the class.

Redirecting. Forces a classified traffic stream to a specified egress port (physical or
LAG). This can occur in addition to any marking or policing action. It can also be
specified along with a QoS queue assignment.

Mirroring. Copies a classified traffic stream to a specified egress port (physical or
LAG). This can occur in addition to any marking or policing action. It can also be
specified along with a QoS queue assignment.

Counting: Updating octet and packet statistics to keep track of data handling along
traffic paths within DiffServ. In this DiffServ feature, counters are not explicitly
configured by the user, but are designed into the system based on the DiffServ policy
being created. For more information, see Port and EAP packet statistics on page 836.
