I have to go through and find out the configuration set up on the old Dell Force10 switches that we have. I was wanting to make sure that I fully understand what is going on with what I see. I have the configuration of the VLANs for the ports below:

[![VLAN Config IDF3][1]][1]

I am just trying to fully understand what this all means. I know that the U is for untagged and that T is for tagged. The question that I have is what the meaning of untagged and tagged has on the ports. I thought that if the port is in use you would want to tag that port with the VLAN that you want it to be on. But I know that untagged is what is getting used because I know they are physically plugged.

So, I am just a little confused. If someone could please help me understand.
