trex测试流程

Trex简单测试

注意

trex主机与dut主机第一个network为管理网，第二个与第三个network为测试用网，trex主机与dut主机测试用网eth1互联，trex主机与dut主机测试用网eth2互联;
只可运行net_set.sh 一次，获得mac地址，若mac地址全为0，重启trex主机;
测试项可在run_trex.sh修改（-m 参数为几万pps -d参数为测试时间）。

步骤

打开trex主机运行trex_set.sh 并得到两个mac地址fa:ad:96:2e:3c:01 fa:0b:32:14:a9:02；
打开dut主机运行 dut_set.sh fa:ad:96:2e:3c:01 fa:0b:32:14:a9:02；
打开trex主机运行run_trex.sh ，等待运行结束得到trex结果。
