在当今高速发展的网络时代，网络设备的稳定性和带宽利用率成为了企业关注的焦点。链路聚合（Link Aggregation，简称LAG）技术应运而生，它可以将多个物理链路捆绑成一个逻辑链路，从而提高网络带宽和冗余性。本文将详细介绍Cisco设备上LACP（Link Aggregation Control Protocol）的配置方法，帮助您轻松实现网络设备链路聚合，提升网络性能。
LACP简介
LACP是一种链路聚合控制协议，它允许网络设备在链路聚合组中动态地协商和同步链路状态。LACP支持两种模式：活性模式（Active Mode）和被动模式（Passive Mode）。活性模式下的设备会主动发送LACP报文，而被动模式下的设备则等待其他设备发送LACP报文。
配置LACP的步骤
1. 创建链路聚合组
首先，在交换机上创建一个链路聚合组，并将需要聚合的物理链路加入到该组中。
