Typical Configuration Of PQ on AR28、AR46 Series Routers
[Requirements]
Server and PC1 send data (wherein, Server sends the key service data and PC1 sends the non-key service data) to PC2 through the router.
In this case, the key service data sent by Server should be preferentially processed in network congestion.

Configuration script
#
acl number 2001 /Define the server traffic/
rule 0 permit source 1.1.1.1 0
acl number 2002 /Define the PC traffic/
rule 0 permit source 1.1.1.2 0
#
qos pql 1 protocol ip acl 2001 queue top
/Specify the acl 2001 traffic to join the top queue/
qos pql 1 protocol ip acl 2002 queue bottom
/Specify the acl 2002 traffic to join the bottom queue/
#
interface Serial0/0
clock DTECLK1
link-protocol ppp
qmtoken 1
/Modify the number of QoS sending token quantity/
ip address 10.1.1.2 255.255.255.0
qos pq pql 1 /Enable the PQ/
[Verification]
The traffic defined by the pql will be transferred at the first time.
[Tip]
1. PQ only takes effect on outbound traffic but is not able to control the inbound traffic.
2. Configure qmtoken 1 (Set the number of QOS sending token) for mid-range routers on the interface. But the low-end routers cannot be configured with it so the effect is much worse.
After configuring this command, execute shutdown / undo shutdown to restart the interface.
