VLAN Terminology Differences between switches

I have a 3COM Baseline 2824 Plus switch that is linked to another Baseline 2816 Plus switch.

I have 3 VLANs established on the 2824 switch which I have some clients belonging to each of those VLANs on the other swtich.

The 2824 switch uses NOT A MEMBER, TAGGED, UNTAGGED for assigning ports to VLANs.  I understand how VLANs work and the differences between tagged and untagged and the various possible combiniations.  Basicaly my VLAN1 is untagged, and the VLAN2 and VLAN3 are tagged.

On teh 2816 switch, the terminology is NOT A MEMBER, UPLINK PORT, DESKTOP PORT.  Do UPLINK and DESKTOP ports funciton the same as TAGGED and UNTAGGED, but just different terminology?

I tried setting a port on the 2816 as a UPLINK PORT, but it assigned this status to all 3 VLANs.  Will this leave VLAN1 as UNTAGGED and TAG VLAN2 and VLAN3 packets?

I can't believe these two are the same series switches, but using 2 different VLAN web configuration interfaces.

I called 3COM support but the agent didn't sound confident in his own advice.  I don't think he knew what he was talking about.

Tagged = trunk.
Untagged = part of that vlan (think cisco: switchport access vlan x).
Not a member = I am unsure - would be orphaned or access related to completely deny access to that port from routing other members of that vlan.

I understand the differences between Tagged vs. Untagged and Not a Member.  It was Desktop vs. Uplink on the other switch that confused me.

I made the assumption that "Desktop" acted like "Untagged" while "Uplink" acted like "Tagged" which based on my tests seems to be the case.  Usually when you have a single port trying to handle multiple VLAN's, you would leave VLAN1 (for example) as Untagged, and VLAN2 and 3 as Tagged.  In this case, all three were left as "Uplink" but seems that all traffic from VLAN1, 2 & 3 was broadcasted to their appropriate virtual networks.

I will be closing this thread as I have figured this out on my own.
