AirTight Management Console Configuration
45
x WPA2: WPA2 is the latest and more robust security protocol. It fully implements the IEEE
802.11i standard.
x WPA and WPA2 mixed mode: This stands for a mix of the WPA and WPA2 protocols.
PSK or Personal Shared key is generally used for small office networks.
In case of bigger enterprise networks, RADIUS authentication is used. Large enterprises, sometimes, use
RADIUS attributes to propagate network policies across multiple points of access. Users are divided into
groups and policies are applied to each group to effectively control access to network resources. Each
user group is redirected to a different VLAN based on the policies applicable to that user group.For
instance, sales personnel would have access to a VLAN that is different from the VLAN accessed by HR
personnel.
An AirTight AP can retrieve the VLAN associated with the RADIUS user from the RADIUS server. This
option is available only for WPA2, and WPA and WPA2 mixed mode when 802.1x is enabled on the Wi-Fi
profile.
Based on the VLAN returned by the RADIUS server, the AirTight AP dynamically redirects the network
traffic of a RADIUS-authenticated user to the VLAN that is associated with the group to which the user
belongs. Until the RADIUS server authenticates the user, the EAP packets will pass through the default
VLAN.
Note: The VLAN ID that is set in the Wi-Fi profile network settings is used as the default VLAN.
To enable RADIUS-based assignment of VLANs, you must enable dynamic VLANs on the Wi-Fi profile
and specify a list of dynamic VLANs that RADIUS users can be redirected to. If the VLAN specific to the
user group is not present, the default VLAN is used.
The following RADIUS attributes must be set on the RADIUS side for each user group for the RADIUS
server and AirTight AP communication.
Attribute Value
Tunnel Type Set this to VLAN.
Tunnel Medium Type Set this to 802.
Tunnel Private Group ID Enter the VLAN ID to be assigned to the user group.
