交换机trunk的配置

这个实验也是有关vlan的，有２台交换机，这样的网络拓扑我的理解在一定程度上可以起到双机热备的作用．因模拟软件无法实现VTP的功能,只能每台配置vlan实验目的:pc1--pc4互通pc2--pc3互通 sw1:
Switch>en
Switch#conf t
Enter configuration commands, .e per line.  End with CNTL/Z.
Switch(config)#host sw1

VLAN 10 added:
    Name:vlan10
sw1(vlan)#vlan 20 name vlan20

sw1(vlan)#endsw1#conf t
Enter configuration commands, .e per line.  End with CNTL/Z.
