15 华三华为链路聚合综述

1 链路聚合简介

以太网链路聚合通过将多条以太网物理链路捆绑在一起形成一条以太网逻辑链路，实现增加链路带宽的目的，同时这些捆绑在一起的链路通过相互动态备份，可以有效地提高链路的可靠性。

2 成员端口的状态

聚合组内的成员端口具有以下三种状态：

· 选中（Selected）状态：此状态下的成员端口可以参与数据的转发，处于此状态的成员端口称为"选中端口"。

· 非选中（Unselected）状态：此状态下的成员端口不能参与数据的转发，处于此状态的成员端口称为"非选中端口"。

· 独立（Individual）状态：此状态下的成员端口可以作为普通物理口参与数据的转发。满足以下条件时，如果成员端口在经过LACP（Link Aggregation Control Protocol，链路聚合控制协议）超时时间之后未收到LACP，则该成员端口会被置为该状态：

¡ 聚合接口配置为边缘端口。

¡ 处于选中/非选中状态的成员端口经过一次down、up后，该成员端口将被置为独立状态

链路聚合分为静态聚合和动态聚合两种模式，它们各自的优点如下所示：

· 静态聚合模式：一旦配置好后，端口的选中/非选中状态就不会受网络环境的影响，比较稳定。

· 动态聚合模式：通过LACP协议实现，能够根据对端和本端的信息调整端口的选中/非选中状态，比较灵活。

处于静态聚合模式下的聚合组称为静态聚合组，处于动态聚合模式下的聚合组称为动态聚合组。

7 动态链路聚合

思路

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) 配置聚合组工作在动态聚合模式下。

link-aggregation mode dynamic

缺省情况下，聚合组工作在静态聚合模式下。

(4) 退回系统视图。

quit

(5) 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 | auto group-id }

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。

指定auto参数时，会开启端口的半自动聚合功能。当配置半自动聚合后，建议用户不要修改自动创建的聚合组及其成员端口的配置，避免影响半自动聚合功能。

(6) 配置端口的LACP工作模式。

LACP（链路聚合控制协议）是一种基于IEEE 802.3ad标准的协议，它主要用于实现链路动态聚合，即将多条物理链路聚合成一条带宽更高的逻辑链路。

LACP模式主要有三种：

主动模式（Active Mode）：在这种模式下，网络设备会主动发送LACP请求帧（LACPDU），并等待对端设备的回应。如果对端设备也支持LACP，并且配置为被动模式，则会回应LACPDU来建立链路聚合。

被动模式（Passive Mode）：在这种模式下，网络设备只接收LACP请求帧，并根据请求进行相应的回应。被动模式的设备通常不主动发送LACPDU，而是等待对端设备在主动模式下发送请求来建立链路聚合。

静态模式（Static Mode）：这是一种不依赖于LACP协议的链路聚合方式。在静态模式下，管理员手动配置链路聚合，而不需要LACP协议的握手过程。静态模式适用于一些不支持LACP的设备，或者在特定情况下需要避免LACP协议的使用。

在你的问题中，lacp mode passive指的是将LACP协议设置为被动模式。在这种模式下，设备不会主动发送LACP请求帧，而是等待对端设备的LACP请求帧来进行回应和链路聚合。

¡ 配置端口的LACP工作模式为PASSIVE。

lacp mode passive

¡ 配置端口的LACP工作模式为ACTIVE。

undo lacp mode

缺省情况下，端口的LACP工作模式为ACTIVE。

(7) （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。

(8) （可选）配置端口的LACP超时时间为短超时（3秒）。

lacp period short

缺省情况下，端口的LACP超时时间为长超时（90秒）。

请不要在ISSU升级前配置LACP超时时间为短超时，否则在ISSU升级期间会出现网络流量中断。有关ISSU升级的详细介绍请参见"基础配置指导"中的"ISSU配置"。

Arduino

interface Bridge-Aggregation234：定义了一个名为"Bridge-Aggregation234"的逻辑链路聚合接口。

link-aggregation mode dynamic：设置链路聚合模式为动态，意味着链路聚合可以自动建立。

interface GigabitEthernet1/0/5、interface GigabitEthernet1/0/6、interface GigabitEthernet1/0/7：分别是三个不同的千兆以太网接口配置。

port link-mode bridge：设置端口的工作模式为桥接模式，这通常用于交换机或路由器上的端口，使其可以作为网络交换的一部分。

combo enable fiber：启用combo端口，允许使用光纤或铜缆，具体取决于插入的模块。

shutdown：关闭接口，使其不活动。

link-aggregation port-priority 100：设置链路聚合的端口优先级为100，这可能用于链路聚合控制，如故障转移。

lacp mode passive：设置LACP（链路聚合控制协议）的工作模式为被动，意味着接口将不会主动尝试建立链路聚合，但会响应其他接口的聚合请求。

port link-aggregation group 234：将这些端口加入到编号为234的链路聚合组中。

SW1-5128interface range GigabitEthernet 1/0/5 to GigabitEthernet 1/0/7：这个命令开始一个接口范围的配置，涵盖了从GigabitEthernet 1/0/5到GigabitEthernet 1/0/7的所有接口。

SW1-5128-if-rangeport link-mode route：这个命令将接口的链路模式设置为"route"。在网络设备上，通常有两种链路模式：桥接模式（bridge）和路由模式（route）。路由模式通常用于路由器接口，允许设备对通过该接口的流量进行路由选择。

10 华为 Eth-Trunk（链路聚合）

1、Eth-Trunk（链路聚合技术 ）

1）eth-trunk可以把多个独立的物理接口绑定在一起，作为一个大带宽的逻辑接口使用。

2、Eth-Trunk优势：

1）增加设备之间的互联带宽

2）提高设备之间的可靠性

3）对流量负载均衡，提高链路利用率

3、Eth-Trunk链路聚合模式

1）手工模式

2）LACP模式

4、手工模式：如下图

1）手工模式下3条活动链路都参与数据转发并分担流量

2）当一条链路故障时，在剩余的2条活动链路中分担流量

5、Eth-Trunk接口配置流程

1）创建eth-trunk

2）选择链路聚合模式

3）在eth-trunk中加入成员接口

6、配置手工模式Eth-trunk

拓扑

需求

1）对交换机之间的链路进行链路捆绑，增加互联带宽

2）确保同 VLAN的 PC 之间互通

配置步骤

1）PC配置IP地址

2）所有交换机创建vlan10 和vlan20

3）交换机和PC互联的接口设置为access ，并加入指定的vlan

4）创建Eth-Trunk

5）配置Eth-Trunk的工作模式为手工模式

6）Eth-Trunk中加入成员接口

配置命令

Haskell

7、LACP模式：如下图：

1）LACP模式也称为M:N模式

2）M条活动链路，N条备份链路

3）当活动链路出现故障时，备份链路才进行转发

8、LACP模式工作原理

确定主动端

确定活动链路

LACP抢占功能

9、确定LACP主动端

1）通过比较两端交换机的系统优先级来确定LACP主动端

2）系统优先级数值越小越优先，默认值是32768

3）如果系统优先级相同，则比较两端设备的MAC地址，越小越优先

10、确定LACP活动链路

1）通过系统优先级选举出LACP主动端后，以主动端的接口优先级来选择活动接口

2）接口优先级数值越小越优先，默认值是32768

3）如果主动端设备的接口优先级相同，则根据接口号的大小来选举活动端口，（接口号越小越优先）

11、配置LACP模式Eth-trunk

拓扑

需求

-PC1和PC3属于vlan 10、PC2和PC4属于vlan 20

-设备之间配置lacp模式的链路聚合，并确保同vlan之间的主机可以互通

配置步骤

1）PC配置IP地址

2）所有的交换机都创建vlan10 20

3. 交换机和pc互联的接口做成access ,并且加入指定的vlan

4）设置交换机的lacp 优先级，确定主动端设备

5. 配置链路聚合

-创建链路聚合组，组号为1

-配置链路聚合的工作模式lacp

-在链路聚合中添加成员接口

-设置接口trunk模式

-设置活动端口（活动链路）的上限阈值为2

-开启lacp 抢占

您提供的文本是华为设备上链路聚合（Eth-Trunk）的配置示例。以下是对这些命令的解释：

Huaweiinterface Eth-Trunk 3：进入华为设备上的逻辑链路聚合接口3的配置模式。

Huawei-Eth-Trunk3mo：这个命令不完整，可能是想要输入mode来设置链路聚合的工作模式。

Huawei-Eth-Trunk3mode m：这个命令同样不完整，应该是想要指定链路聚合的工作模式，但具体模式未指定。

Huawei-Eth-Trunk3mode manual：设置链路聚合为手动模式，这意味着端口是被手动添加到聚合组中，而不是通过协议自动发现。

Huawei-Eth-Trunk3mode ?：列出了可用的链路聚合模式。

lacp-static：静态模式，通常用于LACP（链路聚合控制协议）。

manual：手动模式，端口需要手动配置为聚合的一部分。

Error:Incomplete command found at '^' position.：命令不完整，提示错误。

Huawei-Eth-Trunk3quit：退出当前配置模式。

Huaweiinterface Eth-Trunk 3：重新进入Eth-Trunk 3的配置模式。

Huawei-Eth-Trunk3tr：这个命令不完整，可能是想要输入trunkport来设置链路聚合的成员端口。

Huawei-Eth-Trunk3trunkport ?：列出了添加端口到链路聚合的可用选项。

GigabitEthernet：提示输入GigabitEthernet接口。

Huawei-Eth-Trunk3trunkport GigabitEthernet ?：提示输入具体的GigabitEthernet接口编号。

SW1-Eth-Trunk1port link-type trunk：在另一个设备上，设置端口链路类型为trunk模式。

SW1-Eth-Trunk1port trunk allow-pass vlan 10 20：配置trunk端口允许VLAN 10和VLAN 20的流量通过。

SW1-Eth-Trunk1lacp preempt enable：启用LACP抢占功能，允许该设备在LACP协商中作为主导设备。

请注意，这些命令需要根据实际的网络环境和需求进行调整。链路聚合的配置需要确保两端的设备都支持相应的协议，并且配置一致。此外，VLAN的配置也需要确保网络中其他设备允许相应的VLAN流量通过。
