Dell 6224 will do cross chassis LAGG, Fast Etherchannel etc.  Its compatible
with VMware and it works well with BSD.  Those came out significantly
cheaper than Cisco.

HP makes a stackable series as does Extreme - all are lower priced and less
sucktastic than Cisco.

I have a client using a Dlink. Of some kind with cross-switch LAGG support
as well.

see where to setup the LAGG on the pfSense system. 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.

Failover lagg without bridging won't cause any issues with STP though. 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.
