Identify the ports

./dpdk_setup_ports.py -s

Create a configuration file

cp  cfg/simple_cfg.yaml  /etc/trex_cfg.yaml

trex_cfg.yaml format

- port_limit      : 2
  version         : 2
  interfaces    : ["03:00.0","03:00.1"] 
  port_info       :
          - ip         : 1.1.1.1
            default_gw : 2.2.2.2
          - ip         : 2.2.2.2
            default_gw : 1.1.1.1
  
################ or mac ####################
          - dest_mac : '00:00:00:05:00:00'
            src_mac  : '00:00:00:06:00:00' # new format
          - dest_mac : [0x0,0x0,0x0,0x7,0x0,0x01]
            src_mac  : [0x0,0x0,0x0,0x8,0x0,0x02] # old format

启动stateless服务器

./t-rex-64 -i

基本运行

[bash]>trex-console
trex>start -f stl/udp_1pkt_simple.py -m 10mbps -p 0       #直接运行python脚本
trex>service                                            #切换到service模式下
trex(service)>l2 -p 0 --dst 00:10:10:11:11:11       # L2模式 -p 端口号  --dst 目的MAC
trex(service)>l3 -p 0 --src 192.168.10.11 --dst 192.168.10.168     #L3模式
trex(service)>ping -p 0 -d 192.168.10.168          # -p 端口号  -d dest_ip
trex(service)>arp    #L3模式，端口获得的MAC
trex(service)>portattr    #端口信息

运行python

[bash]>trex-console                                                    #1

# Start the traffic on all ports at 10 mbps.
trex>start -f stl/udp_1pkt_simple.py -m 10mbps -p 0  #-m 后面值可为10 50%

# pause  the traffic on all port
>pause -a

# resume  the traffic on all port
>resume -a

# stop traffic on all port
>stop -a

# show dynamic statistic
>tui
