To get proper redundancy, we've installed 2 Huawei S5700-52C-SI switches in our network and connected them to eachother. We now want to hook our servers to both switches. Since all servers have 2 ethernet ports, this should be possible.

The big problem is that we want to do this using just 1 IP address per server. Does anyone know how to configure Linux (and Windows too actually) so it supports this, at the same time avoiding any form of looping ?

Why do you want to do this if the switches are already connected to each other?

Whatever reason you have: you probably need bridging.

Hi dellpe,

I suspect that you want to setup something like split multi trunking. "The S5700 supports enhanced trunk (E-Trunk) that enables a CE to be dual-homed to two PEs (S5700s)." I was not able to find any further documentation on how to setup an E-Trunk.

Finding documentation on this is a bit difficult, as there are several terms being used:I tried to setup a load-balancing bonding (http://scientificlinuxforum.org/index.php?act=ST&f=9&t=2614&st=0#entry17155). But I failed to configure it so that everything works. I read that setting up monitoring vms(nagios/icinga/shinken...) behind a bounding nic is not easy. wacko.gif

For Windows... I do not even want to know how to do that. It is causing my enough trouble already. http://dl.dropbox.com/u/2835777/BangHead1.gif
And you are probably running SL6x by now... tongue.gif
