主备交换机之间可以端口聚合吗

一、服务器环境和交换机环境

1、服务器

ubuntu18 4.15.0-159-generic

2、交换机

Huawei Versatile Routing Platform Software
VRP (R) software, Version 5.170 (S5720 V200R010C00SPC600)
Copyright (C) 2000-2016 HUAWEI TECH CO., LTD
HUAWEI S5720S-28P-SI-AC Routing Switch uptime is 0 week, 1 day, 5 hours, 8 minutes

3、网卡绑定的作用

当一个网卡不够用的时候，可以使用两个网卡绑定在一起增加带宽
当一个网卡断的话，另一个网卡可以形成备份，增加链路冗余
主备模式只能做成链路备份，不能负载，负载需要服务器和交换机互相配合

4、bond 的七种模式

每种模式的特点可以参考（Linux----bond技术及mode模式详解_weixin_45726050的博客-CSDN博客）

这七种模式分别是：
802.3ad balance-alb balance-tlb broadcast active-backup balance-rr balance-xor

mode=0 round-robin轮询策略(Round-robin policy)
mode=1 active-backup主备策略(Active-backup policy)
mode=2 load balancing (xor)异或策略(XOR policy)
mode=3 fault-tolerance (broadcast)广播策略(Broadcast policy)
mode=4 lacp IEEE 802.3ad 动态链路聚合(IEEE 802.3ad Dynamic link aggregation) #我这边使用是这种模式
mode=5 transmit load balancing适配器传输负载均衡(Adaptive transmit load balancing)
mode=6 adaptive load balancing适配器负载均衡(Adaptive load balancing)

二、服务器配置

1、查看有没有bonding kernel module，一般ubuntu18，默认就有的。

modinfo bonding | head -n 3

#安装ifenslave

apt-get install ifenslave

filename: /lib/modules/4.15.0-159-generic/kernel/drivers/net/bonding/bonding.ko
author: Thomas Davis, tadavis@lbl.gov and many others
description: Ethernet Channel Bonding Driver, v3.7.1

##加入bonding模块

echo "bonding" >>/etc/modules

2、网络配置

vim /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback

auto eno1

iface eno1 inet manual

bond-master bond0

bond-primary eno1

bond-mode 4

auto eno2

iface eno2 inet manual

bond-master bond0

bond-primary eno2

bond-mode 4

auto bond0

iface bond0 inet static

address 192.168.10.113

netmask 255.255.255.0

gateway 192.168.10.254

slaves eno1 eno2

bond-mode 4

bond-miimon 100

bond-downdelay 200

bond-updelay 200

3、重启网卡

#/etc/init.d/networking restart

如果重启网卡报错，就重启机器

4、查看bonding状态

#cat /proc/net/bonding/bond0

三、交换机配置

1、首先进入system-view 进入以太网端口视图

>system-view

#进入聚合口trunk2
interface Eth-Trunk2

#配置为接入模式
port link-type access

# 放行vlan，如果用的是默认的vlan1，那可以不需要执行
port default vlan ID

#模式
mode lacp

#流量分流算法模式，总共有6总，常用的是src-dst-ip
load-balance src-dst-ip

#配置之后可以 dis this 查看一下配置

display this
#
interface Eth-Trunk2
port link-type access
port default vlan 192
mode lacp
#

** 注意：
加入聚合之前请删除端口中的配置**

undo eth-trunk
undo link-type

2、配置聚合端口信息

# 进入g 1/0/19 端口

interface GigabitEthernet1/0/19

#** 加入trunk2**
eth-trunk 2

#跟上面一样进入另一个端口加入聚合

#进入g 2/0/2 端口
interface GigabitEthernet2/0/20

#加入trunk2
eth-trunk 2

查询： dis interface Eth-Trunk 查看所有聚合表

display interface Eth-Trunk

Eth-Trunk2 current state : UP

Line protocol current state : UP

四、验证

验证的方式较为简单，两个网卡同时插上网线，并连接到交换机上，断掉其中任何一个，不影响使用。
