If it fails to respond to a ping after the configured number of retries, it will disable both radios so that no clients can connect to the AP.
Page 48: Radius
4: S HAPTER YSTEM ONFIGURATION RADIUS Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol that uses software running on a central server to control access to RADIUS-aware devices on the network. An authentication server contains a database of user credentials for each user that requires access to the network.
Page 49: Authentication
Authentication Port: The UDP port number used by the RADIUS server for authentication messages. (Range: 1024-65535; Default: 1812) Key: A shared text string used to encrypt messages between the access point and the RADIUS server. Be sure that the same text string is specified on the RADIUS server.
Page 50 4: S HAPTER YSTEM ONFIGURATION use both MAC address and 802.1X authentication, with client station MAC authentication occurring prior to IEEE 802.1X authentication. However, it is better to choose one or the other, as appropriate. IEEE 802.1X is a standard framework for network access control that uses a central RADIUS server for user authentication.
Page 51 Authentication Figure 23 Authentication MAC Authentication – You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the access point or remotely on a central RADIUS server.
Page 52 4: S HAPTER YSTEM ONFIGURATION Local MAC: The MAC address of the associating station is compared against the local database stored on the access point. Use the Local MAC Authentication section of this web page to set up the local database, and configure all access points in the wireless network service area with the same MAC address database.
Page 53 Authentication When 802.1X is enabled, the broadcast and session key rotation intervals can also be configured. Broadcast Key Refresh Rate: Sets the interval at which the broadcast keys are refreshed for stations using 802.1X dynamic keying. (Range: 0-1440 minutes; Default: 0 means disabled) Session Key Refresh Rate: The interval at which the access point refreshes unicast session keys for associated clients.
Page 54: Filter Control

(Default: Disabled) Disabled: Allows management access from wireless clients. Enabled: Blocks management access from wireless clients. Uplink Port MAC Address Filtering Status –...
Page 56: Vlan
4: S HAPTER YSTEM ONFIGURATION VLAN The access point can employ VLAN tagging support to control access to network resources and increase security. VLANs separate traffic passing between the access point, associated clients, and the wired network. There can be a VLAN assigned to each associated client, a default VLAN for each VAP (Virtual Access Point) interface, and a management VLAN for the access point.
Page 57 Filter Control A VLAN ID (1-4094) can be assigned to a client after successful IEEE 802.1X authentication. The client VLAN IDs must be configured on the RADIUS server for each user authorized to access the network. If a client does not have a configured VLAN ID on the RADIUS server, the access point assigns the client to the configured default VLAN ID for the VAP interface.
Page 58: Snmp
4: S HAPTER YSTEM ONFIGURATION SNMP Simple Network Management Protocol (SNMP) is a communication protocol designed specifically for managing devices on a network. Equipment commonly managed with SNMP includes switches, routers and host computers. SNMP is typically used to configure these devices for proper operation in a network environment, as well as to monitor them to evaluate performance or detect potential problems.
