If you use an Aruba switch, you can leave the VLAN ID or the VLAN name field blank. However, for other switches, you must enter information in both fields. For the Aruba switch, you can use these fields to specify either a VLAN or a role or both as follows:
To specify a VLAN, enter the VLAN ID in the VLAN ID field.
To specify a role, enter the role name in the VLAN name field.
For the Aruba switch you can also use this dialog box to set up separate switch actions for multiple roles on one VLAN or multiple VLANS for one role.
See Switch settings.
