thanks Chris. I've had the Vlan failsafe option set to 10 seconds for 4 days now and the boxes have not failed over. You are correct, there is plenty of traffic on our network and I think i'm going to leave it at 10 seconds for the vlans I will be load balancing for. Also, I did set up a mac masquerade for all my vlans and am very impressed with the fail over. Most of the time I won't even lose a packet when I have a ping going against a VIP. The most I have ever lost is one packet.

 

 

Thanks again..

 

 

 

Failover times are indeed very good. Depending on your application, you can always enable connection mirroring if losing a bit of traffic is unacceptable. Since everything important in my network is HTTP, TCP takes care of the necessary retransmissions.
