Finding out Bonding mode of Interface
 

Hi guys need some help.

Here is short description of the problem:

I have have 8 pysical interfaces in my system which i have configured using netdevice_register fuctions.

I have to bond interfaces 1,2 and 3 to bond0 in round robin mode(ie mode=0). And bond interfaces 4 and 5 to bond1 in active backup mode (ie mode=1).

To do this mode i am supplying the bond mode at the time of bond creation throungh insmod(bonding.c) and creating slaves through enslave module.

However a different module of the project needs to know 1. whether a given interface is bonded or not.
2. if yes then what is the bonding mode.

By checking IFF_SLAVE flag of that net_device structure in interface device driver we can know whether interface is bonded or not.

But i do no know how to find out the bonding mode of the interface ie whether it is in the round-robin mode or active standby mode. I couldnt find out where is the kernel storing bonding mode information.

CAN ANYBODY HELP ME ON THIS.

Early reply would be really appreciated. Thanx in advance

These should give you all the information you need (if I understand correctly):
less /proc/net/bond0/info
less /proc/net/bond1/info

Sorry didn't see how old this was until after the fact...

It still helps though.

less /proc/net/bonding/bond0

an example from a real server

[root@m132 network-scripts]# cat /sys/class/net/bond0/bonding/mode
