Deployment Guide

The change in authentication happens when:
● Add or remove an authentication server (RADIUS/TACACS+)
● Modify an AAA authentication/authorization list
● Change to role-only (RBAC) mode
The re-authentication is also applicable for authenticated 802.1x devices. When there is a change in the
authentication servers, the supplicants connected to all the ports are forced to re-authenticate.
Example
Dell(config)#aaa reauthenticate enable
Dell(config)#aaa authentication login vty_auth_list radius
Force all logged-in users to re-authenticate (y/n)?
Dell(config)#radius-server host 192.100.0.12
Force all logged-in users to re-authenticate (y/n)?
