Which feature must be configured on Cisco WLC to prioritize multicast traffic over a wireless network?

Client link is not a recognized Cisco WLC feature for managing or prioritizing multicast traffic over wireless.

mDNS snooping on the Cisco WLC intercepts Bonjour/mDNS multicast service discovery packets and proxies them as unicast responses, allowing the WLC to prioritize and reliably deliver multicast traffic across the wireless network without flooding all clients with raw multicast frames.

Client band select steers dual-band clients toward the 5 GHz radio to reduce 2.4 GHz congestion, but has no function related to multicast traffic prioritization.

Media stream provides reliable delivery of multicast video and audio streaming sessions specifically, but is not the feature used for general mDNS multicast traffic prioritization on the WLC.
