H3C和CISCO交换机做聚合配置实例教学
H3C和CISCO交换机做聚合配置实例教学H3C和CISCO交换机做聚合配置实例教学端口聚合也叫做以太通道，主要用于交换机之间连接。
那么两种不同的交换机怎么做聚合配置呢?下面跟yjbys店铺一起来看看H3C和CISCO交换机做聚合配置实例教程，希望对同学们学习交换机有所帮助!一、网络环境本网络是xx大厦，3台交换机做端口聚合的课题网络环境：H3C_A交换机<----------------->H3C_B交换机<----- ----------------------->cisco(3560)交换机H3C_B交换机做为中心交换机由于带宽需要，加上该9楼上了很多美国著名的avocentKVM的监控设备，需要很大的带宽，因此做了4组的端口链路聚合的需要因此以下配置命令1、H3C_A的.配置如下：(动态链路聚合，LACP默认启动)[H3C_A]sys[H3C_A]int bridge-aggregation 1[H3C_A]link-aggregation mode dynamil[H3C_A]int giabthernet1/0/26[H3C_A_giabthernet1/0/26]duplex full[H3C_A_giabthernet1/0/26]speed 1000[H3C_A_giabthernet1/0/26]port link-type trunk[H3C_A_giabthernet1/0/26]port trunk permit vlan all因此，其它三个端口都是一样，如以上配置就可以了，同时H3C_B也是同样如H3C_A的配置一样，配好了，检查下端口的问题。
2、思科的配置[cisco]int port-channel 2[cisco]swit trunk encapsulation dot1q[cisco]swit mode trunk[cisco]swit trunk allowed vlan all[cisco]进入端口模式配置[cisco]int gig0/19[cisco]duplex full[cisco]speed 1000[cisco]swit trun encapsulation dot1q[cisco]swit mode trunk[cisco]swit trunk allowed vlan all[cisco]channel-group 2 mode active其它的端口同样的配置配置好了在H3C交换机用 dis link-aggregation summary查看信息同时，在思科交换机用show ethernetchannel summary查看信息最后经过上面的配置，端口聚合就可以通了。

链路聚合实验报告
一、实验目的1. 了解链路聚合的基本概念和原理。
2. 掌握二层链路聚合的配置方法。
3. 熟悉链路聚合在实际网络中的应用场景。
二、实验环境1. 交换机：两台H3C S5700交换机2. 网线：直通网线若干3. 计算机终端：2台三、实验步骤1. 拓扑搭建：将两台交换机通过网线连接，并连接一台计算机终端用于配置和测试。
2. 配置交换机：1. 在交换机SW1上：- 创建链路聚合组：`system-view`，`link-aggregation group 1 mode manual`。

2. 在交换机SW2上：- 配置与SW1一致的链路聚合组、VLAN和trunk模式。
3. 测试链路聚合：1. 在计算机终端上配置IP地址，并确保与交换机SW1的VLAN 10在同一网段。
2. 使用ping命令测试计算机终端与另一台计算机终端之间的连通性。
四、实验结果与分析1. 链路聚合成功：在配置完成后，使用ping命令测试计算机终端之间的连通性，结果显示连通性良好，说明链路聚合配置成功。
2. 带宽提升：链路聚合将多个物理接口聚合为一个逻辑接口，从而提高了链路的带宽。

五、实验结论1. 链路聚合是一种提高网络带宽和稳定性的有效方法。
H3C实验报告大全【含18个实验】6-链路聚合
链路聚合配置含义：链路聚合就是将多个物理以太网链路聚合在一起形成一个逻辑上的聚合端口组。
链路聚合的优点：增加链路带宽提供链路可靠性实现数据的负载均衡链路聚合的模式按照聚合方式的不同，链路聚合可以分为两种模式：?? 静态聚合模式?? 动态聚合模式聚合成员端口的状态聚合组中的成员端口有下面两种状态：?? Selected 状态：处于此状态的接口可以参与转发用户业务流量；?? Unselected 状态：处于此状态的接口不能转发用户业务流量。
LACP 协议LACP（Link Aggregation Control Protocol，链路聚合控制协议）是一种基于IEEE802.3ad 标准的协议。
LACP 协议通过LACPDU（Link Aggregation Control Protocol Data Unit，链路聚合控制协议数据单元）与对端交互信息。
处于动态聚合组中的接口会自动使能 LACP 协议，该接口将通过发送LACPDU 向对端通告自己的系统LACP 协议优先级、系统MAC、端口的LACP 协议优先级、端口号和操作Key。
对端接收到LACPDU 后，将其中的信息与其它接口所收到的信息进行比较，以选择能够处于Selected 状态的接口，从而双方可以对接口处于Selected 状态达成一致。
操作Key操作Key 是在链路聚合时，聚合控制根据成员端口的某些配置自动生成的一个配置组合，包括端口速率、双工模式和链路状态的配置（统称为端口属性配置）。
在聚合组中，处于 Selected 状态的成员端口有相同的操作Key。
初步认为是一个组一个key值！可是有聚合ID啊？？？那key就是按照主接口的属性，生成的本聚合组的接口标准属性！聚合组的负载分担类型聚合组可以分为两种类型：负载分担聚合组和非负载分担聚合组。
目前S3610&S5510 系列交换机仅支持负载分担聚合组。
负载分担规则如下：?? 报文的二层转发使用源 MAC 地址和目的MAC 地址作为依据计算所采用的负载分担模式（即决定使用聚合组中哪个端口来转发该报文）；?? 报文的三层转发使用源 IP 地址和目的IP 地址作为依据计算所采用的负载分担模式（即决定使用聚合组中哪个端口来转发该报文）。

第 1 章 链路聚合简介
当候选端口的数目超过这一限制时，系统将按照端口号从小到大的顺序选择一 些候选端口保持在 Selected 状态，端口号较大的端口则变为 Unselected 状态。 z 处于 Selected 状态且端口号最小的端口为聚合组的主端口，其他端口均为聚 合组的子端口。 z 当聚合组中全部成员都处于 down 状态时，编号最小的端口为主端口，但此时 全组成员均为 Unselected 状态。 需要特别指出的是，在手工聚合组中，当处于 Selected 状态的端口数已达到限制时， 除非主端口需要更换，否则后加入的端口即使配置与当前主端口一致且端口号比已 有的 Selected 端口小，也会成为 Unselected 状态。这样处理是为了尽量维持当前 Selected 端口上的流量不中断，但是可能会导致设备重启前后各端口的选中状态不 一致。用户应注意避免这种情况的发生。
2. 手工聚合组中的端口状态 在手工聚合组中，端口可能处于两种状态：Selected 和 Unselected。只有 Selected 端口能够收发用户业务报文，Unselected 端口不能收发用户业务报文。 系统按照以下原则设置端口处于 Selected 或者 Unselected 状态： z 当聚合组内有处于 up 状态的端口时，系统按照端口全双工/高速率、全双工/
