交换机端口聚合

要配置端口聚合时，首先要保证两台交换机所聚合的端口必须工作在半双工方式下，同时还要工作在相同的速率属于相VLAN并且链路也必须一致。

1：

Switch>en
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int vlan 1
Switch(config-if)#ip add 192.168.1.1 255.255.255.0
Switch(config-if)#no shut

%LINK-5-CHANGED: Interface Vlan1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
Switch(config-if)#exit
Switch(config)#int range f0/1 - 2
Switch(config-if-range)#switchport access vlan 1
Switch(config-if-range)#speed 100
Switch(config-if-range)#duplex half

 switch(config-if-range)#channel-group 1 mode on
2.

方法同上

3：1ping 2

Switch#ping 192.168.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
