Cisco Cisco 2504 Wireless Controller Guía Para Resolver Problemas
Multicast applications such as Bonjour require special consideration when being deployed over a
wireless network since a multicast in 802.11 is essentially sent out as a broadcast so all clients
can hear it. The actual data rate used by the AP in order to transmit the Bonjour frames is the
highest mandatory rate configured within that band. For 2.4GHz, this is a default of 11Mbps, and
for 5GHz, this is a default of 24Mbps.

for 5GHz, this is a default of 24Mbps.
In order to optimize the delivery of these frames, it is important to tune the 802.11 data rates within
the controller to allow multicast to be delivered at the highest rate that the coverage model of the
network can support. For networks with a low density of APs, it may be necessary to keep the data
rates at the default. For a network that does not have any requirement to support 802.11b clients,
tuning the data rate to 12Mbps Mandatory and lower rates disabled will help to reduce multicast
airtime utilization. This is configured under the Wireless tab and the 802.11b/g/n > Network menu.

Note: The RF Profiles feature available in v7.2 allows per AP-Group customization of data rates
which allows tuning multicast transmission rates for different coverage areas.
