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.

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

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.

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 WA5620i-ACN

[Sysname-wlan-ap-ap1] radio 1

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.

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

rssi rssi-value: Specifies the RSSI threshold in the range of 1 to 30. The recommended RSSI threshold is 10.

Usage guidelines

This feature enables an AP to ignore packets with a signal strength lower than the specified RSSI threshold. Enabling this feature might cause collisions and interference among devices on the same channel.

Examples

# Enable AP ap1 to ignore weak signals and set the RSSI threshold to 10.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] option signal-ignore enable rssi 10

# Enable APs with model WA4320i-ACN in AP group 1 to ignore weak signals and set the RSSI threshold to 10.

<Sysname> system-view

[Sysname] wlan ap-group 1

[Sysname-wlan-ap-group-1] ap-model WA4320i-ACN

[Sysname-wlan-ap-group-1-ap-model-WA4320i-ACN] radio 1

[Sysname-wlan-ap-group-1-ap-model-WA4320i-ACN-radio-1] option signal-ignore enable rssi 10

option tpc

Use option tpc enable to enable per-packet transmit power control.

Use option tpc disable to disable per-packet transmit power control.

Use undo option tpc to restore the default.

Syntax

option tpc { disable | enable [ minpower minpower | powerstep powerstep | rssistep rssistep | rssithreshold rssithreshold ] }

undo option tpc

Default

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

In an AP group's radio view, per-packet transmit power control is disabled.

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.

rssistep rssistep: Specifies the step value for RSSI adjustment, in the range of 1 to 20. The default value is 10.

rssithreshold rssithreshold: Specifies the RSSI threshold for per-packet transmit power control, in the range of 20 to 95. The default value is 65.

Usage guidelines

This feature enables an AP to dynamically perform transmit power control on a per packet basis. For example, the AP reduces the transmit power when it sends packets to a client with high RSSI. This feature can reduce power consumption, radiation, and interference to improve user experience.

This feature is not applicable to 5 GHz radios of 802.11ac APs.

Examples

# Enable per-packet transmit power control for AP ap1, and set the minimum transmit power to 20.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 2

[Sysname-wlan-ap-ap1-radio-2] option tpc enable minpower 20

# Enable per-packet transmit power control for APs with model WA4320i-ACN in AP group apgroup1, and set the minimum transmit power to 20.

<Sysname> system-view

[Sysname] wlan ap-group apgroup1

[Sysname-wlan-ap-group-apgroup1] ap-model WA4320i-ACN

rrop software-retry

Use rrop software-retry enable to enable software retransmission and set the maximum number of software retransmissions.

Use rrop software-retry disable to disable software retransmission.

Use undo rrop software-retry to restore the default.

Syntax

rrop software-retry { unicast [ eap ] | broadcast-multicast } enable count count

rrop software-retry { unicast [ eap ] | broadcast-multicast } disable

undo rrop software-retry { unicast [ eap ] | broadcast-multicast }

Default

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

In an AP group's radio view, the maximum number of software retransmissions varies by device model.
