思科如何链路聚合配置

思科（Cisco）的链路聚合（也称为端口聚合或链路复用）是一种将多个物理网络接口捆绑成一个逻辑接口的技术，以提高带宽和冗余性。以下是在思科设备上配置链路聚合的基本步骤：

前提条件

1. 硬件支持：确保你的交换机支持链路聚合功能。

2. 端口类型：需要选择支持聚合的端口类型，通常是物理端口或虚拟端口。

配置步骤

1. 创建聚合组（LACP 或静态聚合）

LACP（动态聚合）：

```bash

switch> enable

switch configure terminal

switch(config) interface GigabitEthernet1/0/1

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/2

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/3

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/4

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface port-channel 1

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode lacp

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/1

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode lacp

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/2

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode lacp

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/3

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode lacp

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/4

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode lacp

switch(config-if) exit

switch(config) no shutdown

switch(config) end

```

静态聚合：

```bash

switch> enable

switch configure terminal

switch(config) interface GigabitEthernet1/0/1

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/2

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/3

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface GigabitEthernet1/0/4

switch(config-if) switchport mode access

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) exit

switch(config) interface port-channel 1

switch(config-if) switchport mode trunk

switch(config-if) switchport trunk allowed vlan 1-100

switch(config-if) switchport mode trunk
