Trex初始化配置和server/client的启动
第二章 Trex初始化配置和server/client的启动
一、Trex初始化配置
可以用lspci命令查看网卡的在位情况。下面的01:00.0/01:00.1/05:00.0/05:00.1分别代表网卡的接口。
[root@localhost v2.95]# lspci
01:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
01:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
03:00.0 PCI bridge: Texas Instruments XIO2001 PCI Express-to-PCI Bridge
04:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8169 PCI Gigabit Ethernet Controller (rev 10)
05:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
05:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
切换到trex解压的目录，开始配置要使用的接口。Trex最少需要两个接口，也就是端口对的概念。如果只有一个可用的口，那可以采用dummy来占位。实际的环境已经升级到最新的v2.95，后续就用这个版本来举例。
[root@Trex85 v2.97]# ./dpdk_setup_ports.py -t

#再用如下命令初始化配置，按照提示输入，最终生成默认的配置文件/etc/trex_cfg.yaml.
[root@localhost v2.95]# ./dpdk_setup_ports.py -i
[root@Trex85 v2.97]# cat /etc/trex_cfg.yaml

如果要用到IPv6的接口，添加stack: linux_based。仅仅构造IPv6的报文发送是不需要的。

二、启动server和client
1.启动server
参数的具体含义可以用命令查看 : ./t-rex-64 -h
–vlan 是用82599es的芯片网卡要带的，其他的可以不带
[root@Trex85 v2.97]# ./t-rex-64 -i --stl --vlan --ipv6
Starting Scapy server.... Scapy server is started
Trying to bind to vfio-pci ...
Trying to compile and bind to igb_uio ...
ERROR: We don't have precompiled igb_uio.ko module for your kernel version.

Success.

启动后server窗口就保持实时刷新的状态，一直开着就行了。另外在新链接上开启client。

2.启动client
默认是用python3来启动的，也可以通过加参数–python2强制使用Python2来运行client。
遇到任何疑惑都随时加个-h就能获取详细的帮助。
[root@248 v2.95]# ./trex-console

第一个命令就是portattr查看端口的情况
