4. Configure the following parameters in respect to the intended Multicast Mask:
Multicast Mask Primary Configure the primary multicast mask defined for each listed QoS policy. Normally all multicast and
broadcast packets are buffered until the periodic DTIM interval (indicated in the 802.11 beacon
frame), when clients in power save mode wake to check for frames. However, for certain
applications and traffic types, an administrator may want the frames transmitted immediately,
without waiting for the DTIM interval. By configuring a primary and secondary multicast mask, an
administrator can indicate which frames are transmitted immediately. Setting masks is optional
and only needed if there are traffic types requiring special handling.
Multicast Mask Secondary Set a secondary multicast mask for the WLAN QoS policy. Normally all multicast and broadcast
packets are buffered until the periodic DTIM interval (indicated in the 802.11 beacon frame), when
clients in power save mode wake to check for frames. However, for certain applications and traffic
types, an administrator may want the frames transmitted immediately, without waiting for the DTIM
interval. By configuring a primary and secondary multicast mask, an administrator can indicate
which frames are transmitted immediately. Setting masks is optional and only needed if there are
traffic types requiring special handling.
