What are the difference of TAGGED, UNTAGGED and PVID?



I hope this is the right post I'm looking for.


I have 3com Switch 4200 28 ports V4.0. I'm going to setup the router link to it with 3 VLANs. How can i do that? Can a single switch handle the traffic? I think I need a DHCP Server for the DHCP Clients obtain an ip address with their designated VLAN or segment.



Hoping for your response.



Thank you very much in advance.

Re: What are the difference of TAGGED, UNTAGGED and PVID?

I presume you're talking about network switches.....This is how I see the differences between the 3

UNTAGGED is a regular ethernet data packet

TAGGED is an ethernet data packet with an addition which contains a VLAN ID

A PVID (Port VLAN ID) is an UNTAGGED packet that enters a switch port , the PVID is attched to the untagged packet and forwarded to a VLAN specified by the ID part of the PVID
