[pfSense] NIC Failover

Most of the issues with STP are dealt with via 802.1w (rapid spanning tree)

I have to deconfigure the two nics I want to use and then set them up in failover mode I think.  On the switch side, I was using 2 separate switches with rapid spanning tree on their uplink ports and ports to the pfSense system to assist in fast failover.  I will give it a shot on Monday and see how it goes.

May see switches on occasion that have an issue with a MAC quickly moving from one port to another related to its CAM table, or sometimes with security features on the switch, but that's pretty unusual with typical switch configs. And usually in that scenario you're going to be on two diff switches anyway with failover lagg.
