分析網橋bond及調整網絡卡速度

分析網橋相關bond資訊

１． 檢視所有網橋

[root@node-1 ~]# ip r | grep br-

default via 172.18.0.1 dev br-pub 
10.30.1.0/24 dev br-roller proto kernel scope link src 10.30.1.3 
10.233.0.0/18 dev br-mgmt scope link 
10.233.64.0/24 via 192.168.20.6 dev br-mgmt

[root@node-1 ~]# ovs-vsctl list-ports br-mgmt 

br-mgmt--br-bond1

[root@node-1 ~]# ovs-vsctl list-ifaces br-bond0

１． 確保該網絡卡可以調速

[root@node-3 ~]# ethtool eno1

settings for eno1:
supported ports: [ tp ]
supported link modes:   10baset/half 10baset/full 
100baset/half 100baset/full 
1000baset/full 
supported pause frame use: symmetric
supports auto-negotiation: yes
advertised link modes:  1000baset/full 
advertised pause frame use: symmetric
advertised auto-negotiation: yes
speed: 1000mb/s
duplex: full
port: twisted pair
phyad: 1
transceiver: internal
auto-negotiation: on
mdi-x: off (auto)
supports wake-on: pumbg
wake-on: d
current message level: 0x00000007 (7)
drv probe link

２．調整該網絡卡，限速100m

[root@node-3 ~]# ethtool -s eno1 speed  100 duplex full

[root@node-3 ~]# ethtool eno1
settings for eno1:
supported ports: [ tp ]
supported link modes:   10baset/half 10baset/full 
100baset/half 100baset/full 
1000baset/full 
supported pause frame use: symmetric
supports auto-negotiation: yes
advertised link modes:  100baset/full 
advertised pause frame use: symmetric
advertised auto-negotiation: yes
speed: 100mb/s
duplex: full
port: twisted pair
phyad: 1
transceiver: internal
auto-negotiation: on
mdi-x: off (auto)
supports wake-on: pumbg
wake-on: d
current message level: 0x00000007 (7)
drv probe link
link detected: yes

[root@node-3 ~]# ethtool -s eno1 speed  10 duplex full

[root@node-3 ~]# ethtool eno1
settings for eno1:
supported ports: [ tp ]
supported link modes:   10baset/half 10baset/full 
100baset/half 100baset/full 
1000baset/full 
supported pause frame use: symmetric
supports auto-negotiation: yes
advertised link modes:  1000baset/full 
advertised pause frame use: symmetric
advertised auto-negotiation: yes
speed: 10mb/s
duplex: full
port: twisted pair
phyad: 1
transceiver: internal
auto-negotiation: on
mdi-x: off (auto)
supports wake-on: pumbg
wake-on: d
current message level: 0x00000007 (7)
drv probe link
link detected: yes

[root@node-3 ~]# cat /sys/class/net/eno1/speed

CentOS下bond網絡卡聚合與網橋結合

需求 伺服器配置bond多網絡卡聚合，然後kvm需要使用到網橋，那麼需要做到網橋繫結到bond網絡卡上。實現核心 1 bond配置參考 2 網橋配置參考 3 核心配置 其實只要把bond網絡卡的配置指定為br即可，其餘的不用改變 cat etc sysconfig network scripts i...
