■ Interface view
Description An interface can only use one group of priority lists.
This command can configure multiple classification rules for each group in the priority
list. During traffic classification, the system matches packets along the rule list. If
matching a certain rule, a packet will be classified into the priority queue specified by
this rule; or it will be put into the default priority queue.
CAUTION: Except for interfaces encapsulated with X.25 or LAPB, all physical
interfaces can use PQ.
You can apply queuing configuration to a dialer interface. 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.
