ADD TRAFFICDESCRIPTOR CLASSIFIER
Syntax
ADD TRAFFICDESCRIPTOR=tdname CLASSIFIER=classifiername-list {NCDROP
| NCFORWARD} [NCCOUNT={ON|OFF}]
Description Associates a TRAFFICDESCRIPTOR to one or more CLASSIFIER(s). As a result, the
TRAFFICDESCRIPTOR is applied to all interfaces to which the CLASSIFIER(s) are associ-
ated. A particular TRAFFICDESCRIPTOR may be associated to any number of CLASSIFI-
ERS, but a particular CLASSIFIER may have at most one TRAFFICDESCRIPTOR. Adding a
TRAFFICDESCRIPTOR to a CLASSIFIER limits the ingress traffic flow, for packets match-
ing the CLASSIFIER's match rules, to the RATE and BURSTSIZE indicated by the TRAF-
FICDESCRIPTOR. When an association is added between the TRAFFICDESCRIPTOR
and the CLASSIFIER, some number of actions are added as well: - an Not all RATEs and
BURSTSIZEs are supported on all ports/interfaces. Also, TRAFFICDESCRIPTORs are not
supported on LAG interfaces. If the rate is exceeded and therefore the traffic flow is Out
Of Profile (OOP), the packets can be dropped or forwarded, with the option to count
the dropped or forwarded packets. See the command
CREATE TRAFFICDESCRIPTOR RATE
BURSTSIZE
for help on creating new TRAFFICDESCRIPTORs.
Options The following table gives the range of values for each option that can be specified with
this command and a default value (if applicable).
Example ADD TRAFFICDESCRIPTOR=limit_data CLASSIFIER=qos_data NCDROP
NCCOUNT=ON
Option Description Default Value
CLASSIFIER The name of the classifier(s), separated by a comma
ACTION NCDROP or NCFORWARD action - indicates whether
to drop or forward non-conforming packets. - an indica-
tion of whether to increment the port's “Policed
Count” on each non-conforming packet
(NCCOUNT=ON).
Defaults to not incrementing the counter
(NCCOUNT=OFF).
NCCOUNT=OFF
