For example, if you specify the maximum MCS index as 5 for mandatory rates, rates corresponding to
MCS indexes 0 through 5 are configured as 802.11n mandatory rates.
• Mandatory rates must be supported by the AP and the clients that want to associate with the AP.
• Supported rates allow some clients that support both mandatory and supported rates to choose
higher rates when communicating with the AP.
• Multicast MCS: Specifies 802.11n multicast data rates.
Configuring 802.11n rates
1. Select Radio > Rate from the navigation tree to enter the rate setting page.

2. Configure the 802.11n rate as described in Table 118 .
3. Click Apply.
