We are putting a new switch in place and wanted to use the VLAN feature to make the box act like 2 completely separate switches. I thought this would be a simple process, but due to a very poor explaination in the user manual, it has become un-simple.
We simple want ports 1-8 to act independently from the rest of the ports.
The D-Link has a "VID Table Setting" which allows you to define each port as a "tag port", "untag port" or "not member" for EACH VID that is created.
The Switch also has a "Port VID Setting" which simply allows a PVID to be entered for each port.
I don't know if these 2 "modes" are used in conjunction with each other, or if they are separate methods of configuring the VLAN.
This is from using 3com and Cisco switches, I've never used D-Link managed kit.
When a port is added to a VLAN, it can be tagged or untagged. If it is tagged, some extra (a think 4) bytes get added to the ethernet packet to tag it as belonging to a particular VLAN. The device at the other end (another switch or another host) has to support this and be configured to use the same VLAN IDs. This allows 2 or more VLANs to share the same physical link. You tag them at one end, shove them down the wire, and the switch at the other end can separate the packets out again. This sounds like it is beyond what you need.
I expect all you need is to set ports 1-8 as VLAN 1, untagged, and the rest of the ports to VLAN 2, untagged (or whatever numbers take your fancy). On 3com switches you can look up each VLAN and see which ports it contains, or you can look up each port and see which VLANs it belongs to. It's just different ways of looking at the same information.
