Configuration: Vlans

The VLAN table must contain the exact VLAN name as configured on the switch, this table needs to be filled out when FreeNAC is initially installed.

Fields:

• The Group is used is collect VLANs of the same security level and physical location: if hub detection is enabled, NAC will switch a users VLAN within a VLAN group, to avoid conflicts on hubs.
• The ‘Gui Description’ is the name shown in the Edit tab, and should be easy to understand for first level support staff.
• The Number corresponds to the VLAN number on the switch. This number is only used for documentation.
• The Name must correspond exactly to the VLAN name on the switch.

The “VLAN exception” table is a feature allowing location dependant VLANs i.e. when VLAN naming is not consistent across switches, or not all VLANs are available on all switches. The also the Technical Guide chapter .

• The Switch and DefaultVLAN fields are the standard values, lookups (i.e. indices) into the switch and vlan tables.
• The ‘VLAN on this switch’ is a text field containing the name of the VLAN to be assigned to end-devices that connect to this switch.
• So lets say there is an OfficeLAN and PrinterLAN in the main vlan table, but on switch 'sw101', there is only one LAN called 'LAN1'.
  Then two entries need to be created in the VLAN exception table:
  

  sw101 OfficeLAN LAN1
  sw101 PrinterLAN LAN1
