Configuring 802.11n protection mode
802.11n 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 the RTS
packet, all the devices within the coverage of the AP will not send data within the specified time.
Upon receiving the RTS packet, the client sends a CTS packet, ensuring that all the devices within the
coverage of the client will not send data within the specified time.
•
CTS-to-Self—An AP uses its IP address to send a CTS packet before sending data to a client,
ensuring that all the devices within the coverage of the AP will not send data within the specified
time.

By default:
•
The maximum bandwidth for
802.11a is 30000 kbps.
•
The maximum bandwidth for
802.11b is 7000 kbps.
•
The maximum bandwidth for
802.11g is 30000 kbps.
•
The maximum bandwidth for
802.11n is 180000 kbps.
The configured maximum
bandwidth should be close to and
smaller than the upper limit of the
actual traffic.
NOTE:
For a radio enabled with the intelligent bandwidth guarantee function, the modified maximum bandwidth
takes effect only after you disable and then enable the radio.
