Use undo option client fast-forwarding to disable fast forwarding of AP-to-client data frames.
Syntax
option client fast-forwarding enable level level-value
undo option client fast-forwarding
Default
Fast forwarding of AP-to-client data frames is disabled.
Views
Radio interface view
Predefined user roles
network-admin
Parameters
level level-value: Specifies the fast forwarding level in the range of 1 to 4.
Usage guidelines
This feature enables an AP to forward data frames to clients without extra processing (such as verification and counting) to improve processing efficiency.
Examples
# Enable fast forwarding of AP-to-client data frames.
<Sysname> system-view
[Sysname]interface wlan-radio 1/0/1

Views
Radio interface view
Predefined user roles
network-admin
Usage guidelines
This command takes effect only on 802.11g, 802.11n, and 802.11ac clients.
This feature enables clients to send RTS or CTS frames before transmitting frames to avoid interference from hidden nodes.
Examples
# Enable hidden node protection.
<Sysname> system-view
[Sysname]interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] option client hide-node-protection enable
option client reconnect
Use option client reconnect enable to enable AP-triggered client reassociation.
Use undo option client reconnect to disable AP-triggered client reassociation.
Syntax
option client reconnect enable [ rssi rssi-value ] [ interval interval ]
undo option client reconnect
Default
AP-triggered client reassociation is disabled.
Views
Radio interface view
Predefined user roles
network-admin
Parameters
rssi rssi-value: Specifies the RSSI threshold in the range of 5 to 100. The default and recommended RSSI thresholds are 10 and 20, respectively.
interval interval: Specifies the interval at which an AP detects the signal strength of the clients. The value range for the interval argument is 3 to 10 seconds and the default interval is 3 seconds.
Usage guidelines
This feature enables an AP to send deauthentication frames to a client when the AP detects that the signal strength of the client is lower than the specified RSSI threshold. Then, the client can reassociate with the AP or roam to another AP.
Examples
# Enable AP-triggered client reassociation, and set the RSSI threshold and detection interval to 30 and 5 seconds, respectively.
<Sysname> system-view
[Sysname]interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] option client reconnect enable rssi 30 interval 5
option client reject
Use option client reject enable to enable an AP to reject weak-signal clients.
Use undo option client reject to disable an AP from rejecting weak-signal clients.
Syntax
option client reject enable [ rssi rssi-value ]
undo option client reject
Default
Weak-signal clients are not rejected.
Views
Radio interface view
Predefined user roles
network-admin
Parameters
rssi rssi-value: Specifies the RSSI threshold in the range of 5 to 100. Both the default and recommended RSSI thresholds are 10.
Usage guidelines
This feature enables an AP to reject clients with an RSSI lower than the specified threshold to release channel resources and enhance WLAN performance.
After you enable this feature, wireless clients with an RSSI lower than the threshold might fail to access the WLAN.
After a client accesses the WLAN, an AP will not log off the client with an RSSI lower than the threshold but will reject the client after it disconnects from the network.
Examples
# Enable the AP to reject clients with an RSSI lower than 30 dBm.
<Sysname> system-view
[Sysname]interface wlan-radio 1/0/1
[Sysname-WLAN-Radio1/0/1] option client reject enable rssi 30
option dot11n-restraint

Use undo dot11n-restraint to restore the default.
Syntax
option dot11n-restraint { disable | enable packet-number packet-number packet-length packet-length } [ inbound | outbound ] [ tid tid-number ]
undo option dot11n-restraint
Default
802.11n packet suppression is disabled.

Predefined user roles
network-admin
Parameters
packet-number packet-number: Specifies the maximum number of MPDUs that can be aggregated into an A-MPDU, in the range of 1 to 64. The recommended value is 8.
packet-length packet-length: Specifies the maximum A-MPDU length, in the range of 2000 to 380000 bytes. The recommended value is 6000.
inbound: Specifies 802.11n packet suppression in the inbound direction.
outbound: Specifies 802.11n packet suppression in the outbound direction.
tid tid-number: Specifies a traffic identifier, in the range of 0 to 7. The queue type varies by TID value.
· 0 and 3—AC-BE queue.
· 1 and 2—AC-BK queue.
· 4 and 5—AC-VI queue.
· 6 and 7—AC-VO queue.
If you do not specify this option, 802.11n packet suppression applies to all types of packets.
Usage guidelines
Perform this task to suppress 802.11n packets by defining the maximum number of aggregated MPDUs and the maximum A-MPDU length. The two thresholds take effect at the same time. If either threshold is reached, the AP stops aggregation and sends the A-MPDU.
Examples
# Enable 802.11n packet suppression. Set the maximum number of MPDUs that can be aggregated into an A-MPDU and the maximum A-MPDU length to 30 and 10000 bytes, respectively.

Usage guidelines
A wireless client in sleep state listens for traffic indication map (TIM) information in beacon frames to determine whether the associated AP has buffered packets for it. This feature enables an AP to modify the TIM information in beacon frames to decrease the sleep interval of wireless clients to improve transmission efficiency.
Examples
# Enable decreasing the sleep interval of wireless clients.

Usage guidelines
After you execute the rrop anti-bmc default-action permit command on an AP, the AP forwards all received broadcast and multicast packets.
After you execute the rrop anti-bmc default-action deny command on an AP, the AP discards all received broadcast and multicast packets.
If you execute this command together with the rrop anti-bmc network enable command, the rrop anti-bmc network enable command takes effect.

Syntax
rrop anti-bmc network { disable | { ipv4-simple | ipv6-simple | ipv4-and-ipv6-simple } enable }

Predefined user roles
network-admin
Parameters
ipv4-simple: Enables basic broadcast and multicast packet control for the IPv4 network.
ipv6-simple: Enables basic broadcast and multicast packet control for the IPv6 network.
ipv4-and-ipv6-simple: Enables basic broadcast and multicast packet control for both the IPv4 and IPv6 networks.
Usage guidelines
To save radio resources and improve the forwarding performance, perform the following tasks:
· Configure APs not to forward broadcast or multicast packets through radio interfaces.
· Enable basic broadcast and multicast packet control in an IPv4 network. Then, APs reply to ARP broadcast packets, discard DHCP broadcast packets, and process other IPv4 basic broadcast and multicast packets as follows:
¡ If the rrop anti-bmc default-action deny command is not executed, the APs process other IPv4 basic broadcast and multicast packets normally.
¡ If the rrop anti-bmc default-action deny command is executed, the APs discard other IPv4 basic broadcast and multicast packets.
· Enable basic broadcast and multicast packet control in an IPv6 network. Then, APs discard RS and DHCPv6 broadcast packets, perform unicast forwarding on RA packets, reply to NS packets, and process other IPv6 basic broadcast and multicast packets as follows:
¡ If neither the rrop anti-bmc default-action deny nor the rrop anti-bmc protocol ipv6 deny command is executed, the APs process other IPv6 basic broadcast and multicast packets normally.
¡ If either the rrop anti-bmc default-action deny or the rrop anti-bmc protocol ipv6 deny command is executed, the APs discard other IPv6 basic broadcast and multicast packets.
This command is applicable only when software forwarding is used.
