option 4-way-handshake resend

Use option 4-way-handshake resend to set the maximum number of retransmissions for an EAPOL-Key packet and the retransmission interval.

Use undo option 4-way-handshake resend to restore the default.

Syntax

option 4-way-handshake resend max-count [ interval interval ]

undo option 4-way-handshake resend

Default

The maximum number of retransmissions for an EAPOL-Key packet is three, and the retransmission interval is 300 milliseconds.

Parameters

resend max-count: Specifies the maximum number of retransmissions for an EAPOL-Key packet, in the range of 0 to 3.

interval interval: Specifies the retransmission interval in the range of 200 to 500 milliseconds.

Usage guidelines

In Robust Security Network Association (RSNA) authentication, an AP and a client use EAPOL-Key packets in the four-way handshake to negotiate the keys. After that, the AP and the client periodically exchange EAPOL-Key packets to update the keys.

During key negotiation or update, the AP keeps retransmitting an EAPOL-Key packet until a response is received or the maximum number of retries for an EAPOL-Key packet is reached.

The system starts to count the retries when the maximum number of retransmissions is reached.

To ensure successful RSN key negotiation or update, you can increase the maximum number of retransmissions and the maximum number of retries for an EAPOL-Key packet.

For more information about RSN key negotiation or update, see "Configuring WLAN security."

Examples

# In service template view, set the maximum number of retransmissions for an EAPOL-Key packet to one and the retransmission interval to 400 milliseconds.

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 AP ap1 to reject clients with an RSSI lower than 30 dBm.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA6320

[Sysname-wlan-ap-ap1] radio 1

Parameters

proxy-reply: Enables APs to reply to ARP packets.

unicast-forward: Enables APs to convert ARP packets to unicast packets and then forward them.

Usage guidelines

Configure this feature to reduce ARP packets in the WLAN.

·     With the proxy-reply keyword specified, an AP sends an ARP response instead of forwarding the ARP request if the target IP address in the ARP request matches the client entry on the AP. The sender address in the response is the target IP address. The sender MAC address and the source MAC address at the data link layer both are the MAC address bound to the target IP address in the client entry.

·     With the unicast-forward keyword specified, an AP changes the target MAC address in the ARP request and the destination MAC address at the data link layer to the MAC address bound to the target IP address in the client entry. Then the AP converts the ARP packet to a unicast packet and forwards it.

This feature takes effect only after you use the rrop anti-bmc network ipv4-simple enable command to enable basic broadcast and multicast packet control for the IPv4 network.

Examples

# Configure AP ap1 to reply to ARP packets.

<Sysname> system-view

[Sysname] wlan ap ap1

[Sysname-wlan-ap-ap1] rrop anti-bmc protocol arp mode proxy-reply

# Configure APs in AP group group1 to reply to ARP packets.

Parameters

proxy-reply: Enables APs to reply to ND packets.

unicast-forward: Enables APs to convert ND packets to unicast packets and then forward them.

Usage guidelines

Configure this feature to reduce ND packets in the WLAN.

·     With the proxy-reply keyword specified, an AP sends an ND response instead of forwarding the ARP request if the target IP address in the ND request matches the client entry on the AP. The sender address in the response is the target IP address. The sender MAC address and the source MAC address at the data link layer both are the MAC address bound to the target IP address in the client entry.

·     With the unicast-forward keyword specified, an AP changes the target MAC address in the ND request and the destination MAC address at the data link layer to the MAC address bound to the target IP address in the client entry. Then the AP converts the ND packet to a unicast packet and forwards it.

This feature takes effect only after you use the rrop anti-bmc network ipv6-simple enable command to enable basic broadcast and multicast packet control for the IPv6 network.

Examples

# Configure AP ap1 to reply to ND packets.

rrop client fast-keep-alive

Use rrop client fast-keep-alive enable to enable client fast keepalive.

Use rrop client fast-keep-alive disable to disable client fast keepalive.

Use undo rrop client fast-keep-alive to restore the default.

Syntax

rrop client fast-keep-alive { disable | enable [ count count-value ] [ interval interval-value ] }

undo rrop client fast-keep-alive

Default

In radio view, a radio uses the configuration in the AP group's radio view.

In an AP group's radio view, the client fast keepalive feature is enabled.

Views

Radio view

Predefined user roles

network-admin

Parameters

count count-value: Specifies the maximum number of keepalive packets that an AP can send to a client, in the range of 128 to 2048. The default value is 1024.

interval interval-value: Specifies the keepalive packet sending interval, in the range of 3 to 60 seconds. The default value is 10 seconds.

Usage guidelines

To quickly determine whether clients are online and save radio resources, execute this command to set the maximum number of unicast keepalive packets that an AP can send to a client. The AP logs off a client if it does not receive any replies from the client after sending three groups of keepalive packets within the specified keepalive packet sending interval. Packets specified by the count count-value option are counted as one group of keepalive packet.

This command is mainly used in scenarios with high client mobility. If the network quality is poor, reduce the maximum number of keepalive packets that an AP can send to a client or set a smaller interval. As a best practice, use the default setting in scenarios with stable clients.

The configuration in radio view takes precedence over the configuration in an AP group's radio view.

Examples

# Enable client fast keepalive for AP ap1 and set the maximum number of keepalive packets to 300.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA6320

[Sysname-wlan-ap-ap1] radio 1

sacp roam-optimize traffic-hold enable

Use sacp roam-optimize traffic-hold enable to enable data transmission holding during roaming.

Use undo sacp roam-optimize traffic-hold enable to disable data transmission holding during roaming.

Syntax

sacp roam-optimize traffic-hold enable

undo sacp roam-optimize traffic-hold enable

Default

Data transmission holding during roaming is disabled.

Views

Service template view

Predefined user roles

network-admin

Usage guidelines

With data transmission holding during roaming enabled, the device caches the packets during client roaming and sends the packets to the client after the client roams successfully to reduce the packet loss during client roaming. With data transmission holding during roaming disabled, the device ages out the cached packets after a period of time and will not send the packets to the client. As a best practice, enable this feature in a scenario that is sensitive to packet loss.

To make this feature take effect, enable client association at the AC and enable the AC to forward client data traffic.

This feature is not supported in an AC hierarchy network or inter-AC roaming network.

Examples

# Enable data transmission holding during roaming.

Predefined user roles

network-admin

Parameters

dual-wifi: Specifies dual-WiFi-based application traffic optimization.

qos: Specifies QoS-based application traffic optimization.

Usage guidelines

Application traffic forwarding optimization provides the following benefits:

·     Dual-WiFi-based application traffic optimization—After you enable dual-WiFi-based application traffic optimization and enable dual-WiFi on a wireless client, the client will establish a backup WiFi link with the AP. Data packets of the client will be transmitted through both the primary and backup WiFi links to improve the transmission reliability.

·     QoS-based application traffic optimization—After you enable QoS-based application traffic optimization, the device will preferentially process high-priority packets to improve the downlink transmission rate for audio and video traffic.

This feature is memory intensive. Please be cautious.

This feature is not supported in an AC hierarchy network.
