In the CLI
To configure the video over WLAN enhancements:
1. Enable IGMP proxy or IGMP snooping on the switch.
To enable IGMP proxy:
(host) (config) #interface vlan <id>
(host) (config-subif)#ip igmp proxy gigabitethernet <slot/module/port>
To enable IGMP snooping:
(host) (config) #interface vlan <id>
(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
Setting the DSCP value tags the content as video stream that the APs can recognize.
3. Create an ACL on the switch with the values equivalent to the DSCP mappings to prioritize the video traffic.
Example: The following ACL prioritizes the multicast traffic from the specified multicast group on the switch.
You can also add this ACL to any user role or port:
(host) (config-sess-mcast_video_acl)#any network 224.0.0.0 255.0.0.0 any permit to 40 queue
high 802.1p 5
a. To apply the ACL to a user role:
This example uses the user role authenticated.
(host) (config) #user-role authenticated access-list session mcast_video_acl
b. To apply the ACL to a port:
(host) (config) #interface gigabitethernet <slot/module/port>
(host) (config-if)#ip access-group mcast_video_acl session
4. Configure dynamic multicast optimization for video traffic on a virtual AP profile:
(host) (config)#wlan virtual-ap default
(host) (Virtual AP Profile “default”)#dynamic-mcast-optimization
5. Configure the dynamic multicast optimization threshold value:
(host) (config) #dynamic-mcast-optimization-thresh 6
6. Configure multicast rate optimization for video traffic:
(host) (config) #wlan ssid-profile default
(host) (SSID Profile "default") #mcast-rate-opt
7. Configure ARM scanning for video traffic:
In the default RF ARM profile, enable the video aware scan option. This prevents APs from scanning
when a video traffic is active:
(host) (config) #rf arm-profile default
(host) (Adaptive Radio Management (ARM) profile "default") #video-aware-scan
8. Configure and apply a bandwidth management profile.
Ensure that you configure the WMM traffic management profile to the virtual AP profile, if you have configured the
virtual AP traffic management profile.
a. Enable a bandwidth shaping policy so that the allocated bandwidth share is appropriately used:
(host) (config) #wlan wmm-traffic-management-profile default
(host) (WMM Traffic management profile "default") # enable-shaping
b. Set a bandwidth percentage for the following categories:
