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.

Or rather, always design L2 networks so that spanning tree has nothing to do, i.e. there are never multiple paths. Note that each LAG is considered a single interface for STP purposes. > > If you need survivability for entire switch failure, you either need: > - cross-chassis LAG (Cisco's 3750 series is the cheapest option I know of) > - L3 redundancy, not L2 > - STP > > -Adam > > Joseph Hardeman <[email protected]> wrote: > >>Hey Everyone, >> >>So I can do the failover and yes all of the switches are managed. I did 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.

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. >>_______________________________________________ >>List mailing list >>[email protected] >>http://lists.pfsense.org/mailman/listinfo/list >>_______________________________________________ >>List mailing list >>[email protected] >>http://lists.pfsense.org/mailman/listinfo/list >> > _______________________________________________ > List mailing list > [email protected] > http://lists.pfsense.org/mailman/listinfo/list
