Type set ap {ap number} serial-id {AP Serial ID} model {AP Model }
radiotype {11b (802.11b) | 11g (802.11b/g)}. At default, 11g (802.11b and
802.11g are available) is selected. If you want to use 802.11b only, set 11b as
radio type. To confirm AP serial IDs included in APs, type show version
details. Note that 802.11a is always available in APs and cannot be disabled
by CLI.
The following is an example when serial IDs (987654321), AP models
(WL1500-AP), and Radio Type (802.11b) are specified in the command.
