31• A non-802.11n client associates with the 802.11n AP. In this case, 802.11g protection is alwaysenabled without manual intervention.• The 802.11n AP detects a non-802.11n BSS or some 802.11n packets that are not destined to it.To enable 802.11n protection, issue the dot11g protection enable command.To enable 802.11n protection:Step Command Remarks1. Enter system view. system-view N/A2. Enter WLAN RRM view. wlan rrm N/A3. Enable 802.11n protection. dot11n protection enableOptional.By default, 802.11n protection isdisabled.Enabling 802.11n protectionreduces network performance.Configuring 802.11n protection mode802.11n protection modes include RTS/CTS and CTS-to-self.• RTS/CTS—An AP sends an RTS packet before sending data to a client. After receiving theRTS packet, all the devices within the coverage of the AP do not send data within the specifiedtime. Upon receiving the RTS packet, the client sends a CTS packet. This ensures that all thedevices within the coverage of the client do not send data within the specified time.• CTS-to-Self—An AP uses its IP address to send a CTS packet before it sends data to a client.This ensures that all the devices within the coverage of the AP do not send data within thespecified time.To configure the 802.11n protection mode:Step Command Remarks1. Enter system view. system-view N/A2. Enter WLAN RRM view. wlan rrm N/A3.
