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.

Views

Service template view

Predefined user roles

network-admin

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

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

interval interval: Specifies the retry interval in the range of 2 to 5 seconds.

Usage guidelines

During RSN key negotiation or update, an 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.

If you execute this command for multiple times, the most recent configuration takes effect.

option broadcast-multicast-buffer

Use option broadcast-multicast-buffer enable to enable multicast and broadcast buffering.

Use option broadcast-multicast-buffer disable to disable multicast and broadcast buffering.

Use undo option broadcast-multicast-buffer to restore the default.

Syntax

option broadcast-multicast-buffer { disable | enable [ limit limit ] }

network-admin

Parameters

limit limit: Specifies the maximum number of multicast or broadcast packets that can be buffered. The value range for the limit argument is 1 to 600 and the default value is 100.

Usage guidelines

With this feature enabled, the AC stops sending broadcast and multicast packets and buffers them if an associated client is in sleep state. This mechanism affects the performance of real-time multicast applications.

With this feature disabled, the AC directly sends all broadcast and multicast packets regardless of whether an associated client is in sleep state.

Examples

# Disable multicast and broadcast buffering for AP ap1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] option broadcast-multicast-buffer disable

Parameters

level level: Specifies the channel reuse level in the range of 1 to 10. The recommended channel reuse level is 6.

Usage guidelines

Examples

# Enable channel sharing for AP ap1 and set the power level to 30.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

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.

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.

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.

network-admin

Parameters

cir cir: Specifies the CIR for packets destined to radios on other APs, in the range of 1 to 1300000 Kbps.

Usage guidelines

After you enable the scanning service (such as wireless probing, WLAN location, and WIPS) for an AP, a radio on the AP might receive packets destined to radios on a different AP than the radio. Such packets will increase the CPU usage and decrease the processing efficiency for packets destined to radios on the AP.

To address this issue, configure this command to set a rate limit for packets destined to radios on other APs.

Examples

# Set the CIR to 8 Kbps for packets destined to radios on other APs.

Parameters

minpower minpower: Specifies the minimum transmit power in the range of 1 to 27. The default value is 10.

powerstep powerstep: Specifies the step value for transmit power decrease, in the range of 1 to 15. The default value is 5.

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 450.

Usage guidelines

The client keepalive feature enables an AP to send keepalive packets to clients at the specified interval to determine whether the clients are online. To quickly determine whether clients are online and save radio resources, execute this command to set the maximum number of 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 the specified number of keepalive packets to the client.

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. 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.
