The fields that can be configured are described below: 
Parameter  Description 
Web Authentication State 
Select to enable or disable the global Web authentication state. 
Trap State 
Select to enable or disable the Web authentication trap state. 
Virtual IPv4 
Enter the virtual IPv4 address used here. The virtual IP of Web authentication is 
just the characterization of the Web authentication function on the Switch. All Web 
authentication processes communicate with this IP address, however, the virtual 
IP does not respond to any ICMP packet or ARP request. So it’s not allowed to 
configure virtual IP in the same subnet as the Switch’s IP interface or the same 
subnet as the host PCs’ subnet, otherwise the Web authentication cannot operate 
correctly. The defined URL only takes effect when the virtual IP address is 
configured. The users get the FQDN URL stored on the DNS server to get the 
virtual IP address. The obtained IP address must match the virtual IP address 
configured by the command. If the IPv4 virtual IP is not configured, the IPv4 
access cannot start a Web authentication. 
Virtual IPv6 
Enter the virtual IPv6 address used here. If the IPv6 virtual IP is not configured, 
the IPv6 access cannot start a Web authentication. 
Virtual URL 
Enter the virtual URL used here. This URL can be up to 128 characters long. 
Redirection Path 
Enter the redirection path here. This path can be up to 128 characters long. 
Click the Apply button to accept the changes made. 
 
NOTE: The WAC virtual IP address should be configured before enabling WAC because WAC will not 
function correctly if the virtual IP is not configured.
