Mqprio

The following scenario shows how to configure a MQPRIO qdisc. MQPRIO is a hardware-offloaded multiqueue priority scheduling qdisc that requires external packet classification via traffic policies. This test verifies packet classification across multiple traffic classes including the default class.

Test MQPRIO QDisc 

Description 

In this scenario, a MQPRIO qdisc is configured in DUT0 (eth0 interface) to achieve hardware-offloaded multiqueue priority scheduling. Since MQPRIO does not support software matches, external classification is performed via traffic policies that set the class ID for packets.

Multiple traffic classes are configured and tested:

Class 1: TCP packets destined to port 8080
Class 2: UDP packets destined to port 9090
Class 3: ICMP packets
Class 4: TCP packets destined to port 7070 (no bandwidth limit)
Class 6: Default class for unmatched traffic

Each class is tested individually to verify correct packet classification and counter updates.

Scenario 

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 10.0.0.2/24
set interfaces ethernet eth0 traffic control out QDISC
set interfaces ethernet eth0 traffic policy link-out CLASSIFIER
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set traffic control QDISC type mqprio class 1 bandwidth rate 150
set traffic control QDISC type mqprio class 1 description PORT_8080
set traffic control QDISC type mqprio class 2 bandwidth rate 300
set traffic control QDISC type mqprio class 2 description PORT_9090_TCP
set traffic control QDISC type mqprio class 3 bandwidth rate 200
set traffic control QDISC type mqprio class 3 description ICMP
set traffic control QDISC type mqprio class 4 description NO_BANDWIDTH_LIMIT
set traffic control QDISC type mqprio class 6 description DEFAULT
set traffic control QDISC type mqprio default-class 6
set traffic policy CLASSIFIER rule 1 selector PORT_8080
set traffic policy CLASSIFIER rule 1 set class 1
set traffic policy CLASSIFIER rule 2 selector PORT_9090
set traffic policy CLASSIFIER rule 2 set class 2
set traffic policy CLASSIFIER rule 3 selector ICMP
set traffic policy CLASSIFIER rule 3 set class 3
set traffic policy CLASSIFIER rule 4 selector PORT_7070
set traffic policy CLASSIFIER rule 4 set class 4
set traffic selector ICMP rule 1 protocol icmp
set traffic selector PORT_7070 rule 1 destination port 7070
set traffic selector PORT_7070 rule 1 protocol tcp
set traffic selector PORT_8080 rule 1 destination port 8080
set traffic selector PORT_8080 rule 1 protocol tcp
set traffic selector PORT_9090 rule 1 destination port 9090
set traffic selector PORT_9090 rule 1 protocol udp

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.1/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Ping IP address 10.0.0.1 from DUT0:

admin@DUT0$ ping 10.0.0.1 count 1 size 56 timeout 1

Note

MQPRIO requires external classification. Traffic policies are used to set the class ID for packets before they reach the MQPRIO qdisc.

Step 4: Run command traffic control clear at DUT0.

Step 5: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 8080
admin@DUT0$ monitor test performance client 10.0.0.1 duration 2 port 8080 parallel 1

Step 6: Run command traffic control show at DUT0 and expect this output:

Note

TCP traffic to port 8080 should be classified to class 1. The counters for class 1 should show packets/bytes.

Step 7: Run command traffic control clear at DUT0.

Step 8: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 9090
admin@DUT0$ monitor test performance client 10.0.0.1 duration 2 udp port 9090 parallel 1 bandwidth 500M

Step 9: Run command traffic control show at DUT0 and expect this output:

Note

UDP traffic to port 9090 should be classified to class 2.

Step 10: Run command traffic control clear at DUT0.

Step 11: Ping IP address 10.0.0.2 from DUT1:

admin@DUT1$ ping 10.0.0.2 count 10 size 56 timeout 1 interval 0.1

Step 12: Run command traffic control show at DUT0 and expect this output:

Note

ICMP packets should be classified to class 3.

Step 13: Run command traffic control clear at DUT0.

Step 14: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 7070
admin@DUT0$ monitor test performance client 10.0.0.1 duration 2 port 7070 parallel 1

Step 15: Run command traffic control show at DUT0 and expect this output:

Note

TCP traffic to port 7070 should be classified to class 4, which has no bandwidth limit configured.

Step 16: Run command traffic control clear at DUT0.

Step 17: Initiate a bandwidth test from DUT0 to DUT1

admin@DUT1$ monitor test performance server port 5555
admin@DUT0$ monitor test performance client 10.0.0.1 duration 2 port 5555 parallel 1

Step 18: Run command traffic control show at DUT0 and expect this output:

Note

TCP traffic to port 5555 (which doesn’t match any rule) should be classified to the default class (class 6).
