H3C 交换机链路聚合与服务器 bond0 负载均衡设置

January 3, 2018 • Read: 1863 • 17年实战阅读设置

配置 bond0 上联网络设备也需要做捆绑,如果是冗余的 bond 则上联不用配置

H3Cs5560 交换机

interface Bridge-Aggregation 1
port access vlan 10

创建聚合口,划入vlan

int g 1/0/1

port link-aggregation group 1

聚合的两个物理口都加入集合组

int g 2/0/1

port link-aggregation g 1

服务器

bond0 配置cat ifcfg-bond0

DEVICE=bond0
BOOTPROTO=static
IPADDR=10.0.0.126
NETMASK=255.0.0.0
GATEWAY=10.0.0.1
ONBOOT=yes
USERCTL=no
TYPE=Ethernet

eth1,2... 配置cat ifcfg-eth0

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
MASTER=bond0
SLAVE=yes

配置文件开机启用 bond0

vim /etc/modprobe.d/openfwwf.conf

alias bond0 bonding
options bond0 miimon=1000 mode=0

命令方式启用 bond0 模块

insmod /lib/modules/uname -r/kernel/drivers/net/bonding/bonding.ko miimon=1000 mode=0

其他配置
删除模块命令

rmmod /lib/modules/uname -r/kernel/drivers/net/bonding/bonding.ko miimon=1000 mode=0

license 原因 bond 指定配置文件 mac 地址MACADDR=mac地址
查看状态

cat /proc/net/bonding/bond*
# 查看 bond 状态
ethtool bond0| grep -i speed
# 查看网卡速率如:Speed: 2000Mb/s
display link-aggregation verbose | include /0/2
#Status 状态为 ‘S’

配置脚本. py

#!/usr/bin/env python
