8.1.3.4 Qbu test
If you have two ls1028ardb boards, and link the two eno0 back to back, the test would not need to setup the switch and omit the
step 1,2,3, then just perform step 0,4,5.
If you have only one board, you can set the frame path from eno0 to switch by linking enetc ports MAC0 - SWP0. The setup
enable the switch SWP0 port merging capability, then enetc eno0 could show the preemption capability. Use the setup as shown
in the following figure for the Qbu test.
Figure 30. Qbu test
Before link the cable between ENETC port0 to SWP0, set up the switch up(refer the
) and set IP for ENETC
port0. To make sure linking the ENETC port0 to SWP0, use the steps below:
0. Don't forget to enabling the priority for each traffic class:
tc qdisc add dev eno0 root handle 1: mqprio num_tc 8 map 0 1 2 3 4 5 6 7 hw 1
1. Make sure link speed is 1 Gbps by using the command:
ethtool eno0
2. If it is not 1Gbps, set it to 1 Gbps by using the command:
ethtool -s swp0 speed 1000 duplex full autoneg on
