I am trying to setup a 2nd VLAN on my network using all ports on the switch. From what I understand I need to create the VLAN (VLAN 3) and add ports to it then tag them and then they can be a member of both VLAN's. When I remove a port from the default VLAN and add it to VLAN3 i can then tag it but not add it back to VLAN1 which is what i thought tagging a port allowed. Am I doing something wrong or missing something. i am using the web interface as i don't know the commands as well as I would like.

My goal is to create 2 VLANs so i can add wireless AP's with SSID's on the 2nd VLAN using a different subnet for mobile devices to access the internt without using up all my current IP addresses.

Switches are Foundry FastIron SuperX running software version 03.0.01cT3e1

Hi,

not really sure about the web interface, as all we use is the shell ;)
I assume your current setup looks something like this:

vlan 1 name default by port
untagged ethe0/1/1 to eth0/1/24

Open in new window


To add the second VLAN, you most probably did something like this: (well, at least through the web interface)

vlan 3 name NEWVLAN by port
tagged eth0/1/10 ethe0/1/15 to eth01/20

Open in new window


In order to get the port to run both tagged and untagged, adding the appropriate option to it is required:

interface ethernet 0/1/10
dual-mode 1

Open in new window


This should do it ...

Thanks for the response. I am working in the shell and after deleting the VLAN 3 and recreating it using the shell and then adding port 5/4 and 5/18 to VLAN 3. then I went in and ran the command
dual-mode 1
i get an error that says "not a member of vlan 1"
It removes the port from the default vlan when i add it to the new VLAN.
I have attached a screenshot of the shell commands i executed.

What happens if you reverse the sequence? i.e., have the port in vlan 1, set it to dual mode, then add it to vlan 3?

I tried that. As soon as you remove port 5/4 from VLAN 3 it is no longer tagged and i get error
"cannot set untagged port 5/4 to dual mode"
I tried adding ethe 5/4 to VLAN 1 as untagged and then i was going to try the dual-mode command  but the tagged/untagged commands dont exsist in the default VLAN.

I assume all the ports need to be in the default VLAN.

i created 2 VLANs and added ethe 5/4 and 5/18 to both as tagged ports. but of course now they are not in the default VLAN. what are the impicatioons of those ports not being in the default VLAN.

Again thanks for your time.

I figured it out.

if i followed your advise and configured dual-mode on the port it worked if i didnt add the 1 at the end
dual-mode 1
port not in vlan 1

So i did it this way
dual-mode
and it then let me add the port to both VLAN's

OK, might be slight differences in the OS/Switch versions ... (I think we have 3.1 on ours)
Glad it's working ...

due to different versions of switches there was a slight difference in the command but he sent me down the path to the solution.
