uhmm,
a Subnet is layer 3 and a Vlan is Layer 1, so
Yes.

You need to do your research Millimeter before attempting to answer these
types of questions just like the SCSI question in the A+ group.
VLANs are created at layer 2.

Are you sure?
VLANs are configured by physical switch port, thus layer 1.

Yes, but they don't physically disconnect the ports from communicating with
each other .. the switch simply refuses to forward any MAC frames (= data
link layer, no 2) between different VLANs, in effect creating disjoint
(virtual) LANs.

I found a google search post of someone running 15 subnets and 2600 hosts on
one vlan.
A 2900 shows to be able to handle 16000 MAC addresses.
Broadcast domain with > 500 hosts will be the only point I see working on.
comp.dcom.sys.cisco
Will be able to answer your question.

Your absolutely right, and as with the scsi issue I have no problem
admitting my error.
Time will tell if I can improve my track record. :-)
