auth-mode none

Enables automatic Web Authentication.
Syntax
auth-mode none
no auth-mode none
Command Default

By default, if Web Authentication is enabled, hosts need to login and enter authentication credentials to gain access to the network.

Modes

Web Authentication configuration mode

Usage Guidelines

If a reauthentication period is configured, the host will be asked to re-enter authentication credentials once the reauthentication period ends.

You can configure Web Authentication to authenticate a host when the user clicks the Login button. When a host enters a valid URL address, Web Authentication checks the list of blocked MAC addresses. If the host's MAC address is not on the list and the number of allowable hosts has not been reached, after clicking the Login button, the host is automatically authenticated for the duration of the configured reauthentication period, if one is configured. Once the reauthentication period ends, the host is logged out and must enter the URL address again. If automatic authentication is enabled and a host address is not in the blocked MAC address list, Web Authentication authenticates the host and displays the Login page without user credentials, and then provides a hyperlink to the requested URL site.

Note: Automatic authentication is not the same as permanent authentication. You must still specify devices that are to be permanently authenticated even if automatic authentication is enabled.

Use the show webauth vlan command in VLAN configuration mode to determine if automatic authentication is enabled.

The no form of the command removes the automatic Web Authentication configuration.

Examples

The following example enables automatic Web Authentication. 

device(config)# vlan 10
device(config-vlan-10)# webauth
device(config-vlan-10-webauth)# auth-mode none
