Hello, i have a question regarding to redundant ethernet interfaces support in = FreeBSD (we need adapter fault tolerance). Our system has two ethernet interfaces, each is connected to different = switch for high availability reasons. Currently we use netgraph FEC = module for this task, however it seems that it is not suitable for HA = configuration of this type - we experience small network problems when = running via FEC and two independent switches. When we reconfigured the = network to use just one physical interface, the problems were solved. We = then tried the second physical interface to make sure that there is no = hardware related problem ... it worked like a charm as well. We use = FreeBSD 4.11-STABLE. Is ethernet adapter HA supported in FreeBSD? For example on linux it is possible to select active-pasive mode of = ethernet bonding module (linux alternative). This works perfectly (only = one interface is active at a time, the other is backup). Thanks, Martin
