Thanks Stephen.
It's certainly not a deal breaker for sure, as its a great little virtual appliance (or 5 in my case). For work I find myself needing to lab alot which involves ARP, MAC Tables, SPAN / Monitoring traffic etc.. so I utilise the virtual switches like a real infrastructure, and created a full virtual network so virtual firewalls, core switch, edge switches, servers / clients etc.. etc.. a network in a box.
Sometimes I need to push a lot of traffic, sometimes I just wish copying a file through was quicker. So it's more a nice to have especially since all the virtual appliances I run operate at 1gbps.
Got to say, love the fact Extreme have a free virtual switch. Much kudos to you all.
