Item Description
802.11b
Configure rates (in Mbps) for 802.11b.
By default:
• Mandatory rates—1 and 2.
• Supported rates—5.5 and 11.
• Multicast rate—Automatically selected from the mandatory rates. The
transmission rate of multicasts in a BSS is selected from the mandatory rates
supported by all the clients.
802.11g
Configure rates (in Mbps) for 802.11g.
By default:
• Mandatory rates—1, 2, 5.5, and 11.
• Supported rates—6, 9, 12, 18, 24, 36, 48, and 54.
• Multicast rate—Automatically selected from the mandatory rates. The
transmission rate of multicasts in a BSS is selected from the mandatory rates
supported by all the clients.
Configuring 802.11n MCS
Configuration of mandatory and supported 802.11n rates is achieved by specifying the maximum
Modulation and Coding Scheme (MCS) index.
Select Interface Setup > Wireless > Radio from the navigation tree, and click the Rate tab
Figure 111 Setting 802.11n rate
Table 62 Configuration items
Item Description
Mandatory Maximum MCS
Set the maximum MCS index for 802.11n mandatory rates.
IMPORTANT:
If you select the client dot11n-only option, you must configure the mandatory
maximum MCS.
Multicast MCS
Set the multicast MCS for 802.11n.
The multicast MCS is adopted only when all the clients use 802.11n. If a non
802.11n client exists, multicast traffic is transmitted at a mandatory MCS data
rate.
IMPORTANT:
When the multicast MCS takes effect, the corresponding data rates defined for
20 MHz are adopted no matter whether the 802.11n radio operates in 40 MHz
mode or in 20 MHz mode.
Supported Maximum MCS Set the maximum MCS index for 802.11n supported rates.
