(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:
(host) (WMM Traffic management profile "default") # background 10

(host) (WMM Traffic management profile "default") # voice 20
After you configure the WMM bandwidth management profile, apply it to the virtual AP profile:
(host) (config) #wlan virtual-ap default
(host) (Virtual AP profile "default") #wmm-traffic-management-profile default
9. Enable multicast shaping on the firewall:
(host) (config) #firewall shape-mcast
