This view shows you what VLAN tags the switch knows about. By default, it only knows about "Default VLAN", and all of the ports will be in ACCESS mode on that VLAN.
If you click on the tab to the right of that, you will see the VLAN port config.

This view will show you much more detailed information about the ports themselves.
### Adding and Removing VLAN ID's
To create a VLAN, on the VLAN config overview, click the "Create" button.
Next, select an unused VLAN ID, and enter it into the first box. In the second box, enter a description. Typcially, in COSI, these are in the following format:
```
v[vlan ID]_[purpose]
```
Some examples:
```
v2_cosi_priv (the private COSI network)
v3_cosi_pub (the public COSI network)
```
After that, click Apply below the port listing. Adding ports at this screen tends to (unintuitively) fail.
### Adding VLAN ID's to a port
Depending upon whether your port in question is in ACCESS or TRUNK mode will change the behavior of this step.
In ACCESS mode, when you change the VLAN ID, it will replace any existing VLAN ID with the one you select.
In TRUNK mode, when you change the VLAN ID, it will add/remove the VLAN ID to a list of VLAN ID's that the port is allowed to access.
To add the port to a VLAN, go to the VLAN Config tab, and click Edit under the VLAN you want to add/remove the port from.
You will see the following configuration panel:

Once you do that, select/unselect the ports you want to change (and remember the behavior as listed above).
Click "Apply" to finish and apply the changes.
### Set up an ACCESS port
Click on the Port Config tab. You will see the following:
To change to TRUNK, select the ports on the left that you want to change, then click TRUNK from the dropdown, and then click "Apply".
Do not try to change the PVID here. It will fail (inexplicably).

## Saving Switch Config
To save the config, click on the "Save Config" option on the left menu. When you click, it will ask you if you're sure and save the config. This will take at least a few minutes.
This step is important, since **if the switch reboots, it will reset to this saved config**, rather than any config you have without saving. This is important, because if you lock yourself out of the switch, it resets when you reboot it, so that you don't need to get to the console and reset the switch entirely and loose ALL of the configuration.
