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. (Range: 0-1440 minutes; Default: 0
means disabled)
„
802.1X Reauthentication Refresh Rate: The time period after which a
connected client must be re-authenticated. During the re-authentication
process of verifying the client’s credentials on the RADIUS server, the client
remains connected the network. Only if re-authentication fails is network
access blocked. (Range: 0-65535 seconds; Default: 0 means disabled)
802.1X Supplicant – The access point can also operate in a 802.1X supplicant
mode. This enables the access point itself to be authenticated with a RADIUS
server using a configured MD5 user name and password. This prevents rogue
access points from gaining access to the network.
Local MAC Authentication – Configures the local MAC authentication database.
The MAC database provides a mechanism to take certain actions based on a
wireless client’s MAC address. The MAC list can be configured to allow or deny
network access to specific clients.
„
System Default: Specifies a default action for all unknown MAC addresses (that
is, those not listed in the local MAC database).
• Deny: Blocks access for all MAC addresses except those listed in the local
database as “Allow.”
• Allow: Permits access for all MAC addresses except those listed in the local
database as “Deny.”
„
MAC Authentication Settings: Enters specified MAC addresses and permissions
into the local MAC database.
• MAC Address: Physical address of a client. Enter six pairs of hexadecimal
digits separated by hyphens; for example, 00-90-D1-12-AB-89.
• Permission: Select Allow to permit access or Deny to block access. If Delete
is selected, the specified MAC address entry is removed from the database.
• Update: Enters the specified MAC address and permission setting into the
local database.
„
MAC Authentication Table: Displays current entries in the local MAC database.
