Is it possible to configure the switch port to mode trunk if I m going to put a Pc on that port?

If the answer is yes then what are the adventages and the disadventages of doing this. I've proof this with real switches and configuring the ports as trunk with a pc and the pc can ping other pc that are on the same Vlan or configure as trunk. I would like to know why does that happend?

You can but with caveats. On a normal PC with a nic that cannot tag, you'd only be able to pass traffic on your native vlan. Some server nics allow you to tag traffic. The only advantage that you have to configure a trunk port is when you have a phone and pc connected to the same port where the phone can tag its traffic, but the pc cannot.

HTH,

Hi,

It may work, you can configure an interface connecting to host as a trunk link but only if you want that host to receive data from multiple vlans since trunks allowed all vlans per default.

Usually, on a switch you configure vlans to logically devide the users and to avoid flooding all the users with all the information from multiple vlans which they do not need and which causes unnecessary burden on the ports carrying traffic.

Hope this helps.
