RE: NIC Teaming



Hi Vivek,
Please post the output of cat /proc/net/bonding/bond0

and also /var/log/messages(relevant parts) and dmesg. Prefferably have a
look at these debug files first to try and ascertain why it is not
working before posting them. Sounds like both interfaces are on the same
card so I don't think it is a driver/card problem. What value is your
miimon set to?

Try booting the machine with only eth0 plugged in, then plug in eth1 and
note down the difference between /proc/net/bonding/bond0.

Remove eth0 and look at /proc/... again.

Do the same for eth1.

What I am trying to acertain is whether eth0 is broken completely or
just not started up by the bonding driver when it is suppose to fail
over to eth0. The reverse of that needs to be tested too.

Double check that you have added the slave and master lines to eth0.


Regards

Hi Gerrard

There are 2 ports Eth0 and Eth1. Cables from both the ports are
connected to D-Link single switch (non-manageable). When I plug out
the
cable from port 0 ping stops working

Hi Vivek,
I am assuming you bring up eth1 before shutting down eth0.

How are you shutting down the ports?

Have a look at /proc/net/bonding/bond0 which will tell you a bit more
about the current state of the bond.

It might be a network problem... are both cables plugged into the same
switch? If you are using cisco switches then spanning tree port fast
must be on.
