However, in most cases where a VLAN was used, I've seen it used just this way... to create separate "subnets" on a switch. To steal your phrase, "vlaned subnets". Not truly a subnet, but rather a broadcast domain containing a single subnet, in those cases.
Yeah, I guess, sorta. But I believe that you can run more than one subnet on the same physical or logical network - by using different IPs/Masks/GWs. Not sure why you would, but I understand that its possible.
>>Collision domains are a physical layer issue, I *believe* and has >>nothing to do with upper layer protocols (like VLANs). Probably so, but I wouldn't know. This falls back on my tendency to term a switch as a single collision domain. The point I was trying to raise is that a VLAN doesn't function as a switch would, but rather as a router would. Of course, there is always a counterargument for this as a router functions on a different layer than a VLAN, right?
Right, routers being layer 2 and switches being layer 2 or 3. VLANs on layer 3 (again, pretty sure, I don't want to go to the map ;) ). --------------------------------------------------------------------------- This list is sponsored by: Norwich University EARN A MASTER OF SCIENCE IN INFORMATION ASSURANCE - ONLINEThe NSA has designated Norwich University a center of Academic Excellence in Information Security.
