The authentication arp-reply trigger command enables the function of triggering authentication by ARP response packets.
The undo authentication arp-reply trigger command disables the function of triggering authentication by ARP response packets.
By default, the function of triggering authentication by ARP response packets is enabled.
Usage Scenario
If a client in sleep mode receives an ARP request packet, it replies with an ARP response packet, which triggers authentication. However, the authentication fails because no user name or password is entered when the client is in sleep mode. If the client is awakened before the re-authentication interval (specified by the authentication timer re-authen authen-fail re-authen-time command) expires, the user has to wait for a period of time before triggering authentication again. In this case, you can disable the function of triggering authentication by ARP response packets so that authentication is not triggered by ARP response packets sent by clients in sleep mode.
Precautions
This function is supported only for wired users.
When the function of triggering authentication by ARP packets is disabled, the function of triggering authentication by ARP response packets becomes ineffective.
The function of triggering authentication by ARP response packets takes precedence over the function of triggering authentication by any packets. When the function of triggering authentication by ARP response packets is disabled and the function of triggering authentication by any packets is enabled, authentication cannot be triggered by ARP response packets.
The authentication arp-reply trigger command does not support Portal authentication.
