檢視/修改RedHat Linux網路Bonding Mode (Port Trunking)
檢視目前網路Bonding Mode狀態：
cat /proc/net/bonding/bond0
[root@db01 network-scripts]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.4.0-1 (October 7, 2008)
Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth0
MII Status: up
Speed: 100 Mbps
Duplex: full
Link Failure Count: 2
Permanent HW addr: xxxxxxxxxxxxxxxxxx
Slave Interface: eth1
MII Status: up
Speed: 100 Mbps
Duplex: full
Link Failure Count: 2
Permanent HW addr: xxxxxxxxxxxxxx
手動修改網路設定：
cd /etc/sysconfig/network-scripts/
cat ifcfg-bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
IPADDR=xx.xx.xx.xx
NETMASK=255.255.255.0
例：將round-robin改成active-backup：
於ifcfg-bond0中加入一行：
BONDING_OPTS="miimon=100 mode=1"
重啟network servcie：
/etc/init.d/network restart
[root@db01 network-scripts]# /etc/init.d/network restart
Shutting down interface bond0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface bond0: [ OK ]
檢查網路Bonding Mode狀態：
