n Enable dynamic multicast optimization under VAP profile.
n Configure the dynamic multicast optimization threshold—The maximum number of high throughput
stations in a multicast group. The optimization will stop if the number exceeds the threshold value.
n 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.
Configuring the Video Multicast Rate Optimization parameter overrides the configuration of BC/MC Rate
Optimization parameter for VI-tagged multicast traffic. Multicast traffic that is not VI-tagged behaves the same with
BC/MC as before. If multicast rate is not set, all traffic behaves the same.
n Enable video aware scan on ARM profile—This ensures that AP does not scan when a video stream is
active.
n Optionally, you can configure and apply the WMM bandwidth management profile—The total
bandwidth share should not exceed 100 percent.
n Enable multicast shaping to shape the sudden traffic from the source.
Prerequisites
n You will need the Policy Enforcement Firewall Next Generation (PEFNG) license to enable dynamic multicast
optimization.
n This feature is available only on OAW-40xx Series and OAW-4x50 Series platforms.
In the WebUI
To configure video over WLAN enhancements:
1. Enable IGMP proxy or IGMP snooping on the switch.
To enable IGMP proxy:
a. Navigate to Configuration > Network > IP. Under the IGMP settings, select the Enable IGMP
checkbox.
b. Select the Proxy check box and then the appropriate value from the Interface drop down menu.
c. Click Apply.
To enable IGMP snooping:
a. Navigate to Configuration > Network > IP. Under the IGMP settings, select the Enable IGMP check
box.
b. Select the Snooping check box.
c. Click Apply.
2. Enable wireless multimedia and set a DSCP value for video traffic:
a. Navigate to Configuration > Advanced Services > All Profiles.
b. Under the Profiles column, expand Wireless LAN > SSID Profile and select the profile name.
This example uses the default profile.
c. Click the Advanced tab and select the Wireless Multimedia (WMM) check box.
d. Enter the DSCP value (integer number) in the DSCP mapping for WMM video AC field.
e. Click Apply.
3. Create an ACL on the switch with the values equivalent to the DSCP mappings to prioritize the video traffic:
a. Navigate to Configuration > Security > Access Control and click the Policies tab.
b. Click Add to create a new policy.
c. Enter the appropriate values under Rules to match the DSCP mapping values.
