pop up the console window, send ping 192.168.16.221 –l 1000 -t, (–l Refers to
the number of bytes sent by the packet, -t means to keep sending data.) Run
ping 192.168.16.220 –l 1000 –t in test computer 2 in the same way. If test
computer 1 shows Reply from 192.168.16.221:bytes=1000 time<10ms
TTL=128, test computer 2 displays Reply from192.168.16.220:bytes=1000
time<10ms TTL=128, use CTL+ after running for more than 10 minutes. The C
command terminates the current ping. At this time, the console prints out the
ping packet statistics. If the statistics packet loss rate is 0, the device works
normally. As shown in Figure 2-10.

2.3.3. Fiber port test
Combine the two devices into the fiber optic chain network shown in
Figure 2-11. Each Tx port of each device is connected to the test computer
through a direct-connected network cable, and sends PING commands to each
other. Both parties can correctly ping the other party without losing packets. At
the same time, the LINK/ACT light corresponding to the optical port should be
on. The two optical ports tested are working properly. Test other optical ports in
the same way.
