Hi all,


I was going through this web page:-

http://serverfault.com/questions/146...face-ie-bond01


for setting up bonded network interface in my machine running Centos 5.5


although this tutorial worked like charm , I have got 1 doubt ?

1) what does the line "mode=1 miimon=100" means ?


Setting up bonded interface ?

[root network-scripts]# cat ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

[root network-scripts]# cat ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no

[root network-scripts]# cat ifcfg-bond0
DEVICE=bond0
BONDING_OPTS="mode=1 miimon=100"
BOOTPROTO=none
ONBOOT=yes
NETWORK=10.2.1.0
NETMASK=255.255.255.0
IPADDR=10.2.1.11
USERCTL=no

[root network-scripts]# cat ifcfg-bond0:1
DEVICE=bond0:1
BOOTPROTO=static
ONBOOT=yes
NETWORK=10.2.1.0
NETMASK=255.255.255.0
IPADDR=10.2.1.12
USERCTL=no

miimon :
Specifies the MII link monitoring frequency in milliseconds. This determines how often the link state of each slave is inspected for link failures. A value of zero disables MII link monitoring. A value of 100 is a good starting point.
Somewhere I read that, it is deprecated. Not very sure. I think now bond driver uses netif_carrier_ok to find the link status of its slaves.

mode :
specifies the kind of protocol used by bond driver for its slaves.
balance-rr
active-standby.
xor-mac. etc..
