■ Interface view
Description One interface can only use one group of customized queues.
This command can configure multiple classification rules for each group in the CQL.
During traffic classification, the system matches packets along the rule link. If
matching a certain rule, a packet will be classified into the corresponding priority
queue specified by this rule. If not matching any rule, it will go to the default priority
queue.
CAUTION: Except for interfaces encapsulated with X.25 or LAPB, all physical
interfaces can use CQ.
You can apply CQ to a dialer interface successfully only when default queuing is
configured on its physical interfaces. The configuration, however cannot update to its
physical interfaces immediately if they have connections with their respective
connected devices. Instead, the configuration updates to the physical interfaces the
next time they set up connections.
