What is Dynamic Multicast Optimization (DMO) and how it is configured on Aruba Instant APs?
This article contains:
a. Explanation of how IAPs handle multicast optimization prior to and after 126.96.36.199-3.1.x.x OS version
b. Configuration of Dynamic Multicast Optimization on OS version 188.8.131.52-3.1
Prior to version 184.108.40.206-3.1.x.x, IAP supported the optimization of multicast transmissions by using the lowest-common-denominator unicast rate of all associated clients. However, from 220.127.116.11-3.1 onwards, IAP support Video Dynamic Multicast Optimization (DMO) that provides automatic multicast-to-unicast traffic conversion on the IAP. Multicast IP frames are transmitted over the air from the IAP to the clients using 802.11 unicast headers dynamically. DMO enhances the quality and reliability of streaming video, while preserving the bandwidth available to non-video clients.
Environment : This article applies to all the IAPs running 18.104.22.168-3.1.x.x. Any OS version prior to this does not support this feature.
- Navigate to New WLAN>WLAN Setting. Click Show advanced options.
- Enable “Dynamic multicast optimization”.
- Configure “DMO channel utilization threshold”. As long as this threshold is not breached, multicast IP frames are transmitted over the air from the IAP to the clients using 802.11 unicast headers dynamically. Default is 90%.
