I could see this as being an explanation. But doesn't Dot1Q fit into a standard ethernet frame? I believe so, whereas ISL adds into to the ethernet frame making it bigger. This would explain why older (or even newer) hardware may support Dot1Q but not ISL. >From the responses I've seen posted in this thread, it seems that even an entire group of Cisco "experts" (hehe) are having trouble nailing down exactly what the facts are.
