Table 19 Transmit Rates (continued)
Parameter Default Value
multicast-rate auto for all radio types
To change transmit rates for a service profile, use the following
command:
set service-profile name transmit-rates {11a | 11b | 11g}
mandatory rate-list [disabled rate-list] [beacon-rate rate]
[multicast-rate {rate | auto}]
The following command sets 802.11a mandatory rates for service profile
sp1 to 6 Mbps and 9 Mbps, disables rates 48 Mbps and 54 Mbps, and
changes the beacon rate to 9 Mbps:
WX1200# set service-profile sp1 transmit-rates 11a mandatory
6.0,9.0 disabled 48.0,54.0 beacon-rate 9.0
success: change accepted.
Enforcing the Data Rates
By default, the rate set is not enforced, meaning that a client can
associate with and transmit data to the MAP using a disabled data rate,
although the MAP does not transmit data back to the client at the
disabled rate.
You can configure MSS to enforce the data rates, which means that a
connecting client must transmit at one of the mandatory or standard
rates in order to associate with the MAP. When data rate enforcement is
enabled, clients transmitting at the disabled rates are not allowed to
associate with the MAP.
Configuring MAPs
Description
Data rate of multicast frames sent by
MAP radios.
rate—Sets the multicast rate to a
specific rate. The valid rates depend
on the radio type and are the same
as the valid rates for mandatory.
However, you cannot set the
multicast rate to a disabled rate.
auto—Sets the multicast rate to the
highest rate that can reach all clients
connected to the MAP radio.
