Call Admission Control Settings - Cisco 9971 Deployment Manual

Call Admission Control Settings

Enable Call Admission Control (TSPEC) for Voice and configure maximum bandwidth and reserved roaming bandwidth
percentages for either 5 or 2.4 GHz depending on which band is to be utilized.
Maximum bandwidth default setting for voice is 75% where 6% of that bandwidth is reserved for roaming clients.
Roaming clients are not limited to using the reserved roaming bandwidth, but is to reserve some bandwidth in case all other
bandwidth is utilized.
Will want to ensure load-based CAC is enabled, which is available in the 4.1 release for the Cisco Unified Wireless LAN
Controller, but not currently available on the autonomous access point platform.
Load-based CAC will account for non-TSPEC clients as well as other energy on the channel.
Enable Traffic Stream Metrics (TSM).
