By default, the ARM is triggered to scan all the channels every 10 seconds, and select the best channel for transmission. But when the W-IAP is in a new environment, ARM is triggered to perform frequent scanning of the non-DFS channels every 200 milliseconds, and select the best available channel for transmission. The apfrequent-scan command is introduced in the CLI to enable the W-IAPs to trigger frequent scanning of transmission signals on a radio profile. Wireless connection is affected for a few seconds when the frequent scanning of non-DFS channels is ongoing. The connection is re-established after the ARM selects a valid channel. Typically, a frequent scanning session lasts for less than 10 seconds. Perform the following checks before scanning: l The DFS channels must be skipped (this is done to avoid delays in scanning). l The W-IAP must be on stand-alone mode. l The client-aware parameter must be disabled in the ARM profile. In the CLI The following example triggers ARM scanning on a 2.4 GHz frequency band radio profile: (Instant AP)# ap-frequent-scan 2.4 To verify the status of ARM scanning: (Instant AP)# show ap debug am-config 260 | Adaptive Radio Management Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide
