端口聚合提供冗余备份链路

现在两台交换机SwitchA及SwitchB还有两台PC机分别连接到这两部交换机；开始时这两台交换机有两条链路，

现要对这两条链路进行聚合，具体操作步骤如下：

先创建虚拟局域网并把0/5端口加进去；再创建聚合端口0 AG1并把其设为trunk模式

SwitchA# Conf term

# vlan 10

# nameSales

# exit

# interface fastethernet0/5

# SwitchPort access vlan 10

# exit

# show vlan id 10**显示vlan 10

# interface aggregatePort 1　＊＊创建聚合端口0 AG1

#SwitchPort mode trunk　＊＊ 将AG1设为trunk

#exit

#interface range fastethernet 0/1-2 ＊＊合并端口

# Port-group 1

# show aggregatePort 1 Summary

SwitchA# Conf term

# vlan 10

# nameSales

# exit

# interface fastethernet0/5

# SwitchPort access vlan 10

# exit

# show vlan id 10**显示vlan 10

# interface aggregatePort 1　＊＊创建聚合端口0 AG1

#SwitchPort mode trunk　＊＊ 将AG1设为trunk

#exit

#interface range fastethernet 0/1-2 ＊＊合并端口

# Port-group 1

# show aggregatePort 1 Summary

SwitchB# Conf term

# vlan 10

# nameSales

# exit

# interface fastethernet0/5

# SwitchPort access vlan 10

# exit

# show vlan id 10**显示vlan 10

# interface aggregatePort 1　＊＊创建聚合端口0 AG1

#SwitchPort mode trunk　＊＊ 将AG1设为trunk

#exit

#interface range fastethernet 0/1-2 ＊＊合并端口

# Port-group 1

# show aggregatePort 1 Summary

最后进行C>ping 192.168.10.30并拔掉一条连接线再ping．
