Parameter video-aware-scan voip-aware-scan Description Range As long as there is at least one video - frame every 100 mSec the AP will reject an ARM scanning request. Note that for each radio interface, video frames must be defined in one of two ways: l Classify the frame as video traffic via a session ACL. l Enable WMM on the WLAN's SSID profile and define a specific DSCP value as a video stream. Next, create a session ACL to tag the video traffic with the that DSCP value. Dell's VoIP Call Admission Control - (CAC) prevents any single AP from becoming congested with voice calls. When you enable CAC, you should also enable voip-aware-scan parameter in the ARM profile, so the AP will not attempt to scan a different channel if one of its clients has an active VoIP call. This option requires that scanning is also enabled. Default enabled disabled Usage Guidelines Adaptive Radio Management (ARM) is a radio frequency (RF) resource allocation algorithm that allows each AP to determine the optimum channel selection and transmit power setting to minimize interference and maximize coverage and throughput. This command configures an ARM profile that you apply to a radio profile for the 5 GHz or 2.4 GHz frequency band (see rf dot11a-radio-profile on page 752 or rf dot11g-radio-profile on page 763). Channel Quality Hybrid APs and Spectrum Monitors determine channel quality by measuring channel noise, non-Wi-Fi (interferer) utilization and duty-cycles, and certain types of Wi-Fi retries. Regular APs using the ARM feature derive channel quality values by measuring the noise floor for that channel. Client Match the ARM client match feature continually monitors a client's RF neighborhood to provide ongoing client bandsteering and load balancing, and enhanced AP reassignment for roaming mobile clients. This feature is recommended over the legacy bandsteering and spectrum load balancing features, which, unlike client match, do not trigger AP changes for clients already associated to an AP. Legacy 802.11a/b/g devices do not support the client match feature. When client match is enabled on 802.11ncapable devices, the client match feature overrides any settings configured for the legacy bandsteering, station handoff assist or load balancing features. 802.11ac-capable devices do not support the legacy bandsteering, station hand off or load balancing settings, so these APs must be managed on using client match. When this feature is enabled on an AP, that AP is responsible for measuring the RF health of its associated clients. The AP receives and collects information about clients in its neighborhood, and periodically sends this information to the controller. The controller aggregates information it receives from all APs using client match, Dell Networking W-Series ArubaOS 6.4.x | User Guide rf arm-profile | 748
