5 Configuring Access Point Settings Table 9. Radio Settings Field RTS Threshold Load Balancing Load Utilization RF Scan Other Channels RF Scan Interval RF Scan Sentry RF Scan Sentry Channels Description The RTS threshold specifies the packet size of a request to send (RTS) transmission. This helps control traffic flow through the access point, especially one with a lot of clients. If you specify a low threshold value, RTS packets will be sent more frequently. This will consume more bandwidth and reduce the throughput of the packet. On the other hand, sending more RTS packets can help the network recover from interference or collisions which might occur on a busy network, or on a network experiencing electromagnetic interference. The RTS Threshold value can be between 0 and 2347. If you enable load balancing, you can control the amount of traffic that is allowed on the AP. This field allows you to set a threshold for the percentage of network bandwidth utilization allowed on the radio. Once the level you specify is reached, the AP stops accepting new client associations. If you specify 0 in this field, all new associations will be allowed regardless of the utilization rate. The access point can perform RF scans to collect information about other wireless devices within range and then report this information to the Unified Switch. If you select the Scan Other Channels check box, the radio periodically moves away from the operational channel to scan other channels. Enabling this mode causes the radio to interrupt user traffic, which may be noticeable with voice connections. Changing the channels also causes the radio to lose auto-calibration settings which may degrade the signal quality. When the Scan Other Channels check box is not enabled the AP scans only the operating channel. This field controls the length of time between channel changes during the RF Scan. If you select the RF Scan Sentry check box, the radio primarily performs dedicated RF scanning. The radio passively listens for beacons and traffic exchange between clients and other access points but does not accept connections from wireless clients. In sentry mode, all VAPs are disabled. In this mode, the radio switches from one channel to the next. The length of time spent on each channel is controlled by the scan duration. The default scan duration is 10 milliseconds. The radio can scan channels in the radio frequency used by the 802.11b/g band, the 802.11a band, or both bands. Select the channel band for the radio to scan. NOTE: The band selection applies only to radios in sentry mode. Configuring Wireless Radio Settings 89
