l Enable multicast rate optimization to support higher data rate for multicast traffic in the absence of dynamic
multicast optimization. Dynamic multicast optimization takes precedence over multicast rate optimization up
to the configured threshold value.
l Enable video aware scan on ARM profile—This ensures that AP does not scan when a video stream is active.
l Optionally you can configure and apply WMM bandwidth management profile—The total bandwidth share
should not exceed 100 percent.
l Enable multicast shaping to shape the bursty traffic from the source.
You can either use CLI or WebUI to configure the video over WLAN enhancements.
Pre-requisites
l You will need the Policy Enforcement Firewall Next Generation (PEFNG) license to enable dynamic multicast
optimization.
l This feature is available only on W-7200 Series, W-6000M3, W-3000 Series, and W-600 Series controller
platforms.
In the CLI
1. Enable IGMP proxy or IGMP snooping on the controller.
To enable IGMP proxy:
(host) (config) #interface vlan 1
(host) (config-subif)#ip igmp proxy gigabitethernet 1/3
To enable IGMP snooping
(host) (config) #interface vlan 1
(host) (config-subif)#ip igmp snooping
2. Enable wireless multimedia and set a DSCP value for video traffic.
(host) (config)#wlan ssid-profile default
(host) (ssid-profile “default”)#wmm
(host) (ssid-profile “default”)#wmm-vi-dscp <value>
Example:
(host) (ssid-profile “default”)#wmm-vi-dscp 40
(host) (SSID Profile "default") #show wlan ssid-profile default
SSID Profile "default"

Setting the DSCP value, tags the content as video stream that the APs can recognize.
3. Create an ACL on the controller with the values equivalent to the DSCP mappings to prioritize the video traffic.
