8.1.3 Basic TSN configuration examples on ENETC
The tsntool is an application configuration tool to configure the TSN capability. You can find the file,
/usr/bin/tsntool
and
/usr/lib/libtsn.so
in the rootfs. Run
tsntool
to start the setting shell. The following sections describe the TSN
configuration examples on the ENETC ethernet driver interfaces.
Before testing the ENETC TSN test cases, you need to enable
mqprio
by using the command:
tc qdisc add dev eno0 root handle 1: mqprio num_tc 8 map 0 1 2 3 4 5 6 7 hw 1
8.1.3.1 Linuxptp test
To test 1588 synchronization on ENETC interfaces, use the following procedure:
1. Connect ENETC interfaces on two boards in a back-to-back manner. (For example, eno0 to eno0.)
The linux booting log is as follows:
…
pps pps0: new PPS source ptp0
…
2. Check PTP clock and timestamping capability:
# ethtool -T eno0
Time stamping parameters for eno0:
