KC-S1(config)#int f1/1

KC-S1(config-if)#switchport mode trunk #设置该端口为TRUNK模式

*Mar 1 00:18:29.195: %DTP-5-TRUNKPORTON: Port Fa1/1 has become dot1q trunk

KC-S1(config-if)#no sh

PC-1#ping 192.168.1.2 #PING主机PC-2能通

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 148/174/204 ms

PC-1#ping 192.168.1.3 #PING主机PC-3不通

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.3, timeout is 2 seconds:

….

Success rate is 0 percent (0/4)

同理，主机PC-2上能ping通PC-1,但是不能Ping通PC-3.主机PC-3不能ping通PC-1和PC-2.
