In my impression,most switches can not afford to large number of 802.1q vlan trunk. hundreds of tunk vlan will cause the machine poor performance or crash. I suffer it with some intel's switches before. I heard cisco and other vendor suggest not to use too many vlan trunk in their machine. is it true?
