I was wondering if there are any network card drivers that support link failover between either 2 cards, or 2 ports on the same card? basically, I am looking to have a server hooked to 2 switches and have the link failover (while maintaining IP address) failover to the new port in the event of a dead switch. I currently use this functionality in solaris with a daemon called in.mpathd that uses interface aliases as floating ip's between network interfaces. Solaris will failover and back, any links that fail for any reason. Its nice in that besides load balancing to all interfaces in a group, I can use any number of interfaces on any card as a group. I know some of the multiport ethernet cards such as the intel dual-port and dlink quad-port claim failover capabilities, but I suspect that is only for windows. is this correct? Is there any ability in the drivers fro these cards to accomodate failover? Oh...and I know I can write a script in an hour or so to perform this duty and unless I find any new info here, is what I will be doing. I just dont care to reinvent a sub-standard wheel if a nice round one already exists ;) Thanks, Bill --------------------------------------------------------- Bill Desjardins - bill@carracing.com - (USA) 305.205.8644 http://www.EtherneXt.com - High-Performance Co-Location http://www.FreeBSD.org - The Best OS money cant buy!
