新的交换机里有vlan且只有一个默认vlan1  id=1 pvid =1

测试PC1

PC>ping 1.1.1.2

Ping 1.1.1.2: 32 data bytes, Press Ctrl_C to break

From 1.1.1.2: bytes=32 seq=1 ttl=128 time=109 ms

From 1.1.1.2: bytes=32 seq=2 ttl=128 time=109 ms

From 1.1.1.2: bytes=32 seq=3 ttl=128 time=140 ms

From 1.1.1.2: bytes=32 seq=4 ttl=128 time=110 ms

From 1.1.1.2: bytes=32 seq=5 ttl=128 time=78 ms

--- 1.1.1.2 ping statistics ---

  5 packet(s) transmitted

  5 packet(s) received

  0.00% packet loss

  round-trip min/avg/max = 78/109/140 ms

1.当交换机与交换机之间以access时，该端口只能承载单个VLAN的流量（如PC，打印机，IP电话等）。

2.每个端口都需要配置相应的vlan。

3.此时只能ping通在同一vlan2下的PC1与PC2。
