server-name: Name of a Portal server. It is a string in the range of 1 to 32 
characters.

Use the portal command to enable the Portal authentication function on a VLAN 
interface.

Use the undo portal command to disable this function.

If the Portal runs in the Layer 3 Portal authentication method, you must configure 
an authentication section before enabling the Portal authentication function on a 
VLAN interface.

When you enable the Portal authentication function on a VLAN interface, you 
must first make sure that VLAN IDs are in the range of 2 to 4094, and the make 
sure that a valid IP address is configured for this VALN interface and that the 
specified Portal server exists.

# Enable the Portal authentication function on VLAN-interface 10. Specify 3Com 
as the Portal server.

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.

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.
