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.

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
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 WA6330
[Sysname-wlan-ap-ap1] radio 1

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.

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.

Parameters
unicast: Configures software retransmission for unicast packets.
eap: Configures software retransmission for EAP packets.
broadcast-multicast: Configures software retransmission for broadcast and multicast packets.
count count: Specifies the maximum number of software retransmissions, in the range of 0 to 16.
Examples
# Set the maximum number of software retransmissions for EAP packets to the default for radio 1 of AP ap1.

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 [ advanced ]
undo sacp roam-optimize traffic-hold enable
Default
Data transmission holding during roaming is disabled.
Views
Service template view
Predefined user roles
network-admin
Parameters
advanced: Enables advanced data transmission holding during roaming. If you do not specify this keyword, only data transmission holding during roaming is enabled.
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.
With advanced data transmission holding during roaming enabled, the device caches the data packets and sends the cached packets to the client to reduce the packet loss when the client signal strength is lower than the RSSI threshold specified by client anti-sticky. With advanced 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 advanced data transmission holding during roaming in the BSS roaming scenario enabled with client anti-sticky.
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.
