NOTE: Changes to EDCA parameters require a reboot of the AP to take effect.
• Index: read-only. Indicates the index of the Access Category (1-4) being defined:
– 1 = Best Effort
– 2 = Background
–3 = Video
–4 = Voice
• CWMin: minimum Contention Window. Configurable range is 0 to 255.
• CWMax: maximum Contention Window. Configurable range is 0 to 65535.
• AIFSN: Arbitration IFS per access category. Configurable range is 2 to 15.
• Tx OP Limit: The Transmission Opportunity Limit. The Tx OP is an interval of time during which a particular QoS
enhanced client has the right to initiate a frame exchange sequence onto the wireless medium. The Tx OP Limit
defines the upper limit placed on the value of Tx OP a wireless entity can obtain for a particular access category.
Configurable range is 0 to 65535.
• MSDU Lifetime: specifies the maximum elapsed time between a MSDU transfer request and delivery to the
destination, beyond which delivery becomes unnecessary. Configurable range is 0 to 500 seconds.
• Admission Control Mandatory: Possible values are True or False. Admission control defines if an Access Point
accepts or rejects a requested traffic stream with certain QoS specifications, based on available channel capacity
and link conditions. Admission control can be configured for each Access Category (Index).
On the Policy sub-tab, the user can also configure a medium maximum threshold for all Admission Controls.
Admission will be granted if the new requested traffic stream and already admitted time is less than the medium
maximum threshold.
Radius Profiles
Configuring Radius Profiles on the AP allows the administrator to define a profile for RADIUS Servers used by the system
or by a VLAN. The network administrator can define RADIUS Servers per Authentication Mode and per VLAN.
The AP communicates with the RADIUS server defined in a profile to provide the following features:
• MAC Access Control Via RADIUS Authentication
• 802.1x Authentication using RADIUS
• RADIUS Accounting
Also, RADIUS Based Management Access allows centralized user management.
The network administrator can configure default RADIUS authentication servers to be used on a system-wide basis, or in
networks with VLANs enabled the administrator can also configure separate authentication servers to be used for MAC
authentication, EAP authentication, or Accounting in each VLAN. You can configure the AP to communicate with up to six
different RADIUS servers per VLAN/SSID:
• Primary Authentication Server (MAC-based authentication)
• Back-up Authentication Server (MAC-based authentication)
• Primary Authentication Server (EAP/802.1x authentication)
• Back-up Authentication Server (EAP/802.1x authentication)
• Primary Accounting Server
• Back-up Accounting Server
The back-up servers are optional, but when configured, the AP will communicate with the back-up server if the primary
server is off-line. After the AP has switched to the backup server, it will periodically check the status of the primary
RADIUS server every five (5) minutes. Once the primary RADIUS server is again online, the AP automatically reverts
from the backup RADIUS server back to the primary RADIUS server. All subsequent requests are then sent to the
primary RADIUS server.
