Does Cisco think a switch port can be on more than one VLAN?

Well, this is a certification discussion group. What counts is what is a correct answer on the CCNA exam, which doesn't include voice. In class they taught that a port can only be on one vlan, one practice test expected that answer too. Another practice test expected that it…

Different practice exams expect different answers. My experience is that on my OLD OLD 1900, which only supports 4 vlans, that a switch port can be on as many vlans as you want. On the newer 1912 and 1924 switches, I can not find a way to put a port on more than one vlan.



The truth does not matter, what matters is what Cisco would consider to be a correct answer. Does anybody know?

And I think the question was worded to not imply trunkig, but a regular port to connect to a computer.

Using a trunking protocol, you can associate many vlans with a port. Also on some switches, you can configure a voice, or auxiliary, vlan even when you've set the port to access mode.

The answer is 1 VLAN only.

To support more than 1 VLAN the port would have to detect which VLAN the Ethernet frame belonged to which is only possible by using a trunking protocol which a PC connected to an access port does not provide.

do as cisco says not as cisco does

ccna = 1 bcmsn = many
