• Restart service in the absence of controller – Select this option (if
using a bridged at AP VNS) to ensure the Wireless AP’s radios continue
providing service if the Wireless AP’s connection to the HiPath Wireless
Controller is lost. If this option is enabled, it allows the Wireless AP to start
a bridged at AP VNS even in the absence of a HiPath Wireless Controller.
• Use broadcast for disassociation – Select if you want the Wireless AP
to use broadcast disassociation when disconnecting all clients, instead of
disassociating each client one by one. This will affect the behavior of the
AP under the following conditions:
• If the Wireless AP is preparing to reboot or to enter one of the special
modes (DRM initial channel selection).
• If a BSSID is deactivated or removed on the Wireless AP.
This option is disabled by default.
9. In the Advanced dialog Radio Settings section, do the following:
•DTIM – Type the desired DTIM (Delivery Traffic Indication Message)
period — the number of beacon intervals between two DTIM beacons. To
ensure the best client power savings, use a large number. For example,
5. Use a small number to minimize broadcast and multicast delay. The
default value is 5.
• Beacon Period – Type the desired time, in milliseconds, between
beacon transmissions. The default value is 100 milliseconds.
• RTS/CTS – Type the packet size threshold, in bytes, above which the
packet will be preceded by an RTS/CTS (Request to Send/Clear to Send)
handshake. The default value is 2346, which means all packets are sent
without RTS/CTS. Reduce this value only if necessary.
• Frag. Threshold – Type the fragment size threshold, in bytes, above
which the packets will be fragmented by the AP prior to transmission. The
default value is 2346, which means all packets are sent unfragmented.
Reduce this value only if necessary.
• Max % of non-unicast traffic per Beacon period – Enter the maximum
percentage of time that the AP will transmit non-unicast packets
(broadcast and multicast traffic) for each configured Beacon Period. For
each non-unicast packet transmitted, the system calculates the airtime
used by eack packet and drops all packets that exceed the configured
maximum percentage. By restricting non-unicast traffic, you limit the
impact of broadcasts and multicasts on overall system performance.
• Maximum Distance – Enter a value from 100 to 15,000 meters that
identifies the maximum link distance between APs that participate in a
WDS. This value ensures that the acknowledgement of communication
between APs does not exceed the timeout value predefined by the 802.11
standard.
The default value is 100 meters. If the link distance between
