2.2.3 qos pq
Syntax
qos pq pql pql-index
undo qos pq
View
Interface view
Parameter
pql-index: PQL index, ranging 1 to 16.
Description
Use the qos pq command to apply a group of priority list to an interface.
Use the undo qos pq command to restore the congestion management policy at the
interface to FIFO.
By default, the congestion management policy at the interfaces is FIFO.
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.
