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.
To configure the 802.11n protection mode:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
3. Configure the 802.11n
protection mode. dot11n protection-mode { cts-to-self |
rts-cts }
Optional.
By default, the 802.11n protection
mode is CTS-to-Self.
Configuring the maximum bandwidth
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
3. Configure the maximum
bandwidth.
• 802.11a
dot11a max-bandwidth
11a-bandwidth
• 802.11b
dot11b max-bandwidth
11b-bandwidth
• 802.11g
dot11g max-bandwidth
11g-bandwidth
• 802.11n
dot11nmax-bandwidth
11n-bandwidth
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.
