Trying to setup VLANs using Dell PowerConnect 2748 on my network and was successful getting it to work using these directions:

- VLAN Membership page: click "Create VLAN" radio button, enter 201 in the vlan field, set port 1 to 'T' (for tagged), set port 2 to 'U' for untagged, click "Apply Changes"

- VLAN Membership page: click "Create VLAN" radio button, enter 301 in the vlan field, set port 1 to 'T' (for tagged), set port 3 to 'U' for untagged, click "Apply Changes"

- VLAN Membership page: click "Create VLAN" radio button, enter 401 in the vlan field, set port 1 to 'T' (for tagged), set port 4 to 'U' for untagged, click "Apply Changes"

- VLAN Port Setting page: Leave "Interface" set to "Port 1", set "PVID" to 201 (not really necessary), set "Frame Type" to "Admit Tag Only", click "Apply Changes"

- VLAN Port Setting page: Change"Interface" to "Port 2", set "PVID" to 201, click "Apply Changes"

- VLAN Port Setting page: Change"Interface" to "Port 3", set "PVID" to 301, click "Apply Changes"

- VLAN Port Setting page: Change"Interface" to "Port 4", set "PVID" to 401, click "Apply Changes"

My problem is, I hard coded the IP address of the PowerConnect 2748 with an IP off the network for say VLAN 201. Now I can't access the switches via the web interface even though the machine I am trying to access the switch from is on VLAN 201. I can't even ping the ip address that I gave it either. Everything else works great otherwise and I can ping / access everything else on networks VLAN 201, 301 as well as 401.

I just want to be able to make changes to the config...what am I doing wrong?

You set the frame type to "Admit Tag Only".  This means the port will only accept 802.1Q tagged frames.  This is probably pointless as your PC is sending untagged frames destined for VLAN 201 (as specified by the PVID).

If you can set your NIC to use VLAN tagging, set it to VLAN ID 201 and try to ping the switch using the IP address you configured on it.  If you can ping it you should be able to browse to the GUI and change the Frame Type to "Allow All" (I think that's what the option says, but its similar if not exact).
