Usage Guideline
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. If the IPv6
virtual IP is not configured, the IPv6 access cannot start a Web authentication.
Example
This example shows how to configure the Web authentication virtual IPv4 to be "1.1.1.1" and the
FQDN URL to be "www.website4.co".
Switch# configure terminal
Switch(config)# web-auth virtual-ip
Switch(config)# web-auth virtual-ip
Switch(config)#
This example shows how to Switch# configure terminal configure the Web authentication virtual IPv6
to be "2000::2" and the FQDN URL to be "www.website6.co".
Specifies the Web authentication virtual IPv4 address.
Specifies the FQDN URL for Web authentication The FQDN URL
can be up to 128 characters.
Specifies the Web authentication virtual IPv6 address.
