designating the incoming color value to be used as the conforming color. The color of
exceeding traffic can 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. For
more information, see Statistic s on page 75.
•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 can also be specified along
with a QoS queue assignment.
