•

mark cos: the 802.1p user priority bits are (re)marked and forwarded

•

mark dscp: the packet DSCP is (re)marked and forwarded

•

mark prec: the packet IP Precedence is (re)marked and forwarded

•

send: the packet is forwarded without DiffServ modification

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, IP DSCP, or IP Precedence fields
designating the incoming color value to be used as the conforming color. The color of
exceeding traffic may be optionally specified as well.

•

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. See
the Statistics section of this document for more details.

•

Assigning QoS Queue

: directs traffic stream to the specified QoS queue. This allows a

traffic classifier to specify which one of the supported hardware queues are used for
handling packets belonging to the class.

•

Redirecting

: forces classified traffic stream to a specified egress port (physical or LAG).

This can occur in addition to any marking or policing action. It may also be specified along
with a QoS queue assignment.

DiffServ Example Configuration

To create a DiffServ Class/Policy and attach it to a switch interface, follow these steps:

From the QoS Class Configuration screen, create a new class with the following

settings:
