bonding on SLES10

sushant_01 — Tue, 24 Apr 2007 10:07:31 GMT

Guys,

I am trying to configure the bonding on SLES 10, I am referring the doc available on Novell site and the /usr/src/linux/Documentation/networking/bonding.txt.

My bond0 interface is up and running , but when I try to stop one of the slave interface, the entire bond0 interface also disables.

I used ifdown eth1 command , and after I try the ifconfig command displays no bond0 interface.

So actually speaking if I fail any of the slave interfaces the bond0 interface also gets disabled.

What could be wrong here?

Shalom Sush,

Four things too look at.

ifcfg-bond0
ifcfg-eth0
ifcfg-eth1
modprobe.conf

Improper settings in any of the above can lead to this behavior.

It could also be due to the switch settings on the network. Check with your network admin.

For further assistance from me, you'll need to show me the contents of the files above.

Also take a look at /var/log/messages for any clues when this happens.

This is not normal behavior. I've run tests like this in my RH boxes and bond0 stays up so long as one Ethernet card is working.
