思科链路聚合是将多个物理链路捆绑成一个逻辑链路,从而提高链路的可靠性和带宽利用率。以下是思科链路聚合的配置命令:
1. 配置链路聚合组:
```shell
Switch(config)#interface port-channel <channel-group-number>
```
其中,`<channel-group-number>`是链路聚合组的编号,可以是1-65535之间的任意数字。
2. 配置链路聚合组的协议:
```shell
Switch(config-if)#channel-protocol <lacp|pagp>
```
其中,`<lacp|pagp>`是链路聚合控制协议,可以选择LACP或者PAGP。
3. 将物理接口加入链路聚合组:
```shell
Switch(config-if)#channel-group <channel-group-number> mode <active|passive>
```
其中,`<channel-group-number>`是链路聚合组的编号,`<active|passive>`是链路聚合组的模式,可以选择主动模式或者被动模式。
4. 配置链路聚合组的模式:
```shell
Switch(config-if)#switchport mode <access|trunk>
```
其中,`<access|trunk>`是链路聚合组的模式,可以选择接入模式或者交换模式。
以下是一个示例配置,将两个物理接口聚合成一个逻辑链路:
```shell
Switch(config)#interface port-channel 1
Switch(config-if)#channel-protocol lacp
Switch(config-if)#exit
Switch(config)#interface range gigabitEthernet 1/0/1-2
Switch(config-if-range)#channel-group 1 mode active
Switch(config-if-range)#switchport mode trunk
Switch(config-if-range)#exit
```
