Configuring Modulation Rates on a WLAN SSID
APs allow you to enable or disable modulation rates for a radio band; High Throughput (HT)
Modulation and Coding Scheme (MCS) set; and Very High Throughput (VHT) MCS rates
set, when configuring a WLAN SSID profile. For example, the 802.11g band supports the
modulation rate including 1, 2, 5, 6, 9, 11, 12, 18, 24, 36,
48, 54 Mbps and 802.11a band supports a modulation rate set including 6, 9, 12, 18, 24, 36,
48, 54 Mbps.
The 802.11 radio profiles support basic modulation and transmission rates. The 802.11g
basic modulation rates determine the 802.11b/g rates for the data that are advertised in
beacon frames and probe response and 802.11g transmission rates determine the
802.11b/g rates at which the AP can transmit data.
For 802.11n clients, you can now configure an HT MCS rate set so that the SSID does not
broadcast the disabled MCS rates list.
For 802.11ac clients, only 10 MCS rates supported in the 802.11ac mode and APs use a
combination of VHT MCSs and spatial streams to convey the supported MCS rates.
To configure modulation rates:
(scalance)# config terminal
(scalance)(config)# wlan ssid-profile <ssid_profile>
(scalance)(SSID Profile "<ssid_profile>")# a-basic-rates 6 9 12 18
(scalance)(SSID Profile "<ssid_profile>")# a-tx-rates 36 48 54
(scalance)(SSID Profile "<ssid_profile>")# supported-mcs-set 1,3,6,7
(scalance)(SSID Profile "<ssid_profile>")# vht-support-mcs-map 7, 9, 8
(scalance)(SSID Profile "<ssid_profile>")# end
