Derived Classifiers (D) - Allied Telesis SwitchBlade x3100 Series Manual

Introduction
The precedence setting for classifiers should be 51 to 68 for classifiers that perform a filtering action,
Note:
with 69 used for dropping packets that do not match any of the filtering criteria.
The precedence setting for classifiers that remark packets for the QoS function should be 146 to 199.
Note:
6.3.2.4 Example of configuring a Video Classifier
When there is no remarking of p-bits (default settings), the network is being configured so that the p-bits set-
tings are set by the upstream device. The user can, however, set the p-bit to a different value and place it in a
different queue. For example, multicast video traffic could be placed in a high priority by remarking the p-bit to
6 which places it in queue 7 on interfaces supporting 8 queues and on queue 3 on interfaces supporting 4
queues. The example will show it being placed in queue 4. The user can create the classifier as follows:
The ports 11.0-11.3 are all upstream
•
The precedence setting is 146 (within the remarking range)
•
The name of the classifier is remark_mulitcast
•
officer SEC>> create class remark_multicast IPDEST=MULTICAST
officer SEC>> add action class remark_multicast SETVPRIORITY=4

Note that when configuring classifiers, the FULL display for the classifiers for an interface will also include infor-
mation that has been derived from the classifiers. This will be shown with a (D) next to the classifier attribute.
Refer to the next subsection.

Note that when configuring classifiers, the FULL display for the classifiers for an interface will also include infor-
mation that has been derived from the classifiers. For example, a user has configured a classifier set as shown
below.
