12 华三的二层链路聚合
配置思路
1. 配置二层静态聚合组
(1) 进入系统视图。
system-view
(2) 创建二层聚合接口，并进入二层聚合接口视图。
interface bridge-aggregation interface-number [ lite ]
创建二层聚合接口后，系统将自动生成同编号的二层聚合组，且该聚合组缺省工作在静态聚合模式下。
指定lite参数时，将创建精简型二层聚合接口；如果不指定lite参数，则创建普通二层聚合接口
(3) 退回系统视图。
quit
(4) 将二层以太网接口加入聚合组。
a. 进入二层以太网接口视图。
interface interface-type interface-number
b. 将二层以太网接口加入聚合组。
port link-aggregation group group-id [ force ]
多次执行此步骤可将多个二层以太网接口加入聚合组。指定force参数时，会将聚合口上的属性配置同步给该接口。
(5) （可选）配置端口优先级。
link-aggregation port-priority priority
缺省情况下，端口优先级为32768。

华三的二层链路聚合是指华三交换机通过将多个物理链路绑定在一起，形成一个逻辑链路，从而提高链路的带宽和可靠性。二层链路聚合也被称为端口聚合或链路聚合。华三的二层链路聚合支持IEEE 802.3ad标准，可以将最多16个物理链路绑定在一起，形成一个逻辑链路组。
通过二层链路聚合，华三交换机可以将多个物理链路看作一个逻辑链路来使用。这样可以提供更高的带宽，提高数据传输速率和吞吐量。另外，当其中一个物理链路出现故障时，其他链路可以继续工作，提高了链路的可靠性和冗余性。
华三的二层链路聚合支持LACP（链路聚合控制协议），可以实现链路的动态聚合和自动故障转移。LACP可以协调多个交换机之间的链路聚合，使得链路聚合的配置和维护更加简单和灵活。
华三的二层链路聚合还支持静态链路聚合，可以手动配置链路聚合。静态链路聚合不需要LACP协议的支持，可以适用于一些对链路聚合进行更精细控制的场景。
总之，华三的二层链路聚合可以提供更高的带宽和可靠性，提高网络的性能和稳定性。
