Parameter
interval: Interval of ARP handshakes in seconds, in the range of 10 to 180. Its step
is 10. It is 60 seconds by default.
retry-times: Maximum retry times of ARP packets, that is to say, the maximum
times of permitted handshake failures. This value is in the range of three times to
10 times. It is five times by default.
Description
Use the portal arp-handshake command to configure the interval of handshakes
between the portal server and the host and the maximum retry times.
Use the undo portal arp-handshake command to restore the default value.
When authentications are performed in the Direct method or ReDHCP method,
the switch handshakes with the host through ARP packets after the host (user PC)
has passed the Portal authentication. The switch sends ARP packets at the interval.
