Wfq Hw
The following scenario shows how to pre-classify packets to skip WFQ qdisc matches. Hardware-offload is enabled.
Test WFQ Pre-Classification With Hardware-Offload
Description
In this scenario, a WFQ qdisc is configured in DUT0
(eth4 interface) to achieve linksharing
among a hierarchy of classes.
Since hardware offload is configured, CEETM is used
internally.
Scenario
Step 1: Set the following configuration in DUT0 :
set interfaces ethernet eth4 address 10.0.0.2/24 set interfaces ethernet eth4 traffic control out QDISC set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set traffic control QDISC type wfq bandwidth 100 set traffic control QDISC type wfq class 1 weight 50 set traffic control QDISC type wfq class 2 weight 30 set traffic control QDISC type wfq class 8 weight 20 set traffic control QDISC type wfq default-class 8 set traffic control QDISC type wfq hardware-offload set traffic control QDISC type wfq match 1 class 1 set traffic control QDISC type wfq match 1 ip destination port 8080 set traffic control QDISC type wfq match 2 class 2 set traffic control QDISC type wfq match 2 ip protocol tcp
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 1Show output
PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data. 64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=0.299 ms --- 10.0.0.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.299/0.299/0.299/0.000 ms
Step 4: 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 5 port 8080 parallel 1Expect this output in

Step 5: Initiate a bandwidth test from DUT0 to DUT1
admin@DUT1$ monitor test performance server port 1234 admin@DUT0$ monitor test performance client 10.0.0.1 duration 5 port 1234 parallel 1Expect this output in
DUT0:Connecting to host 10.0.0.1, port 1234 [ 5] local 10.0.0.2 port 57412 connected to 10.0.0.1 port 1234 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 13.0 MBytes 109 Mbits/sec 0 387 KBytes [ 5] 1.00-2.00 sec 10.7 MBytes 89.7 Mbits/sec 0 423 KBytes [ 5] 2.00-3.00 sec 11.7 MBytes 98.5 Mbits/sec 0 489 KBytes [ 5] 3.00-4.00 sec 11.1 MBytes 93.3 Mbits/sec 0 544 KBytes [ 5] 4.00-5.00 sec 11.4 MBytes 95.9 Mbits/sec 0 544 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-5.00 sec 58.0 MBytes 97.3 Mbits/sec 0 sender [ 5] 0.00-5.00 sec 55.5 MBytes 93.1 Mbits/sec receiver iperf Done.
Step 6: Run command traffic control show at DUT0 and check if output contains the following tokens:
