Configuring a DNS Server for Enhanced web authentication

If you use a host name to configure access to a web server on which customized login web pages are stored, you must first configure a Domain Name System (DNS) server to resolve the web server's host name into a target IP address. (If you specify an IP address to configure a web server, it is not necessary to configure a DNS server.)

For example, the following web server host name requires the configuration of a DNS server to resolve the host (webserver1) and domain name (accounts.hpe.com) into a target IP address.

To configure switch access to a DNS server to support the use of a host name in the aaa port-access web-based ewa server command, see the “Troubleshooting” chapter in the management and configuration guide for your switch.
