Views
System view
Default command level
2: System level
Parameters
rssi: Specifies an RSSI in the range of 1 to 40 dBm. H3C recommends that you set the RSSI to 20 dBm.
2g: Specifies 2 GHz radios.

Usage guidelines
The AP triggers client reconnection when the RSSI of a client is lower than the specified RSSI to enable the client to reconnect to the AP or roam to another AP.
If you specify the signal-check keyword in the command, the AP does not trigger client reconnection immediately when the RSSI of a client is lower than the specified RSSI. The AP triggers reconnection for the client only if the next detected RSSI of the client is reduced by a minimum of 3 dBm.

<sysname> system-view
[sysname] wlan option client-reconnect-trigger 20
# Enable client reconnection triggering for 2 GHz radios.
<sysname> system-view
[sysname] wlan option client-reconnect-trigger 20 2g
# Enable client reconnection triggering for 5 GHz radios.
<sysname> system-view
[sysname] wlan option client-reconnect-trigger 20 5g

Views
System view
Default command level
2: System level
Parameters
packet-number max-packets: Specifies the threshold for the number of MPDUs aggregated in an A-MPDU, in the range of 1 to 64. H3C recommends that you set the value of the max-packets argument to 8.
