信道绑定接口的MAC地址分配

Question

我已经用balance-alb (mode=6)选项配置了通道绑定(在RHEL/CentOS上)：

BONDING_OPTS="mode=balance-alb miimon=100 updelay=200 downdelay=200"

它工作得很好，根据/proc/net/bonding/bond0的说法，主动从是eth1.

[root@baba ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.4.0-1 (October 7, 2008)

Bonding Mode: adaptive load balancing
Primary Slave: None
Currently Active Slave: eth1
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 200
Down Delay (ms): 200

Slave Interface: eth0
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:19:00:00:00:fb

Slave Interface: eth1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:06:11:11:11:3b

(我有意将MAC的中间部分替换为00和11 )

现在，根据ifconfig，eth0和eth1的MAC地址分配是不同的(与上述输出不同)--它们是交换的。

[root@baba ~]# ifconfig | sed -n '/^[a-z]*[0-9]/p'
bond0     Link encap:Ethernet  HWaddr 00:19:00:00:00:FB  
eth0      Link encap:Ethernet  HWaddr 00:06:11:11:11:3B  
eth1      Link encap:Ethernet  HWaddr 00:19:00:00:00:FB  

有谁知道我为什么看到这个或者它是如何工作的吗？提前谢谢。干杯！！

Answer 1

1) eth0加入该键，该键取0‘S MAC地址。

( 2) eth1加入键。

3)由于某种原因，eth1成为主动奴隶，并出现了以下行为：

If the receiving slave fails, another slave
takes over the MAC address of the failed
receiving slave.

MAC地址的改变似乎如预期的那样起作用。
