How do I create an additional VLAN on Dell 5548p and assign ports?


I would say I am an intermediate in networking, but I can't figure out how to perform the following. Specific instructions on how to accomplish this would be greatly appreciated.

Currently, I have WiFi APs that are powered by regular AC power and are connected via CAT5E to a 5-port unmanaged switch, which is uplinked to a SonicWALL, then to the internet. This separates all WiFi traffic from our main network. If the people using WiFi need access to our main network, they need to connect to the VPN first.

Dell PowerConnect 5548P Gb Switch
SonicWALL TZ200 Firewall
Various WiFi APs

I have several new WiFi APs that I need to have connected to a POE switch that will need to be logically, completely separate from the existing network (default VLAN1) and will be up-linked to a port on the SonicWALL that will then route to the internet. Basically, I just want to segregate ports to make their own separate switch to get the benefit of the POE.

I am thinking that it should be setup like this:
Default VLAN1: Ports 1-42
WiFi VLAN2: Ports 43-48
Where VLAN1 and VLAN2 are completely isolated from each other.
Ports 43-47 are connected to WiFi APs
Port 48 is connected to the SonicWALL.

Anyone care to weigh-in on how to accomplish this? I have tried the 5548p web interface but it is surprisingly confusing. The best the help link can do is just restate the terms and not actually tell me how to do it. The manual is marginally better.

This should help.

I will see if I can modify the 2 switch scenario to make it a single switch. Thank you.

Will the 5-port still be in use or is the PoE switch going to replace it as well?

The 5 port is going to be replaced by this VLAN solution.

I got hung up at int range g because that syntax did not work so I decided to move to individual ports and then got caught at switchport forbidden. It is not a valid option...

I get the following options to use with switchport:

I appreciate any help. Thanks.

This is what the start to finish ended up looking like. I have yet to fully test it, as I have multiple users connected to the WAPs (during business hours).

So far:
I verified that I could get a DHCP address using an IP phone on VLAN 1 and was able to get to the phone server, which is on another switch.

I plugged the same phone into port 46 and was unable to get a DHCP address, which is exactly what I wanted because I have yet to connect the SonicWALL (will be DHCP for VLAN 2) to port 48.

I will have to connect the WAPs and SonicWALL to VLAN 2 after hours and test connectivity and functionality to confirm everything is configured correctly.

After some very minor tweaking, the solution was what I needed. Thanks.
