Usage guidelines
All physical interfaces, except interfaces with X.25 or LAPB encapsulation enabled, can use PQ.
An interface can use only one PQ list.
Multiple match criteria can be configured for a PQ list. During traffic classification, the system matches
packets with the rules in the PQ list. If a packet matches a certain rule, it is assigned to the priority queue,
and the matching process is over. If a packet does not match any rule, it is allocated to the default priority
queue.
You must enable the line rate function for the queuing function to take effect on these interfaces: tunnel
interfaces, subinterfaces, HDLC link bundle interfaces, and VT/dialer interfaces configured with PPPoE,
PPPoA, PPPoEoA, PPPoFR, or MPoFR (frame relay traffic shaping is not enabled on the frame relay
interface).
Examples
# Apply PQ list 12 to Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] qos pq pql 12
