That timer is a bonding module parameter and should not change without the
module reloading.

I guess the might if the network script does modprobe without parameters and it
overwrites your settings in modprobe.conf.


My configuration files is below and they are working.

root@xxxxx:~ # cat /etc/sysconfig/nic/ifcfg-*
DEVICE=bond0
ONBOOT=yes
MODULE=bonding
MODULE_OPTS='mode=1 miimon=100'
BONDING_MASTER=yes
BONDING_SLAVES='eth0 eth1'
DHCP=no
IP="10.3.2.134"
NETMASK="255.255.255.0"
BROADCAST="10.3.2.255"
ROUTE="$ROUTE default/0.0.0.0:10.3.2.1"

-----------------------------------------
DEVICE=eth0
ONBOOT=yes
MODULE="tg3"
DHCP=no
IP=''
NETMASK=''
BROADCAST=''

-----------------------------------------

DEVICE=eth1
ONBOOT=yes
MODULE="tg3"
DHCP=no
IP=''
NETMASK=''
BROADCAST=''

I'm not sure it's necessary, because bonding parameters are defined in network
configuration file.

Probably you are right. But I'd tell that if network script doesn't bring up the
network, it should not stop it either. With "ONBOOT=no" network script really
ignore settings.

I use DL with bonding (mode 1 though) and it seems to be very stable.
