CONFIGURING USER AUTHENTICATION
Renewing DCHP – DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the switch is moved to another network segment, you will lose management access to the switch. In this case, you can reboot the switch or submit a client request to restart DHCP service.
Web – If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the Web interface. You can only restart DHCP service via the Web interface if the current address is still available.
CLI – Enter the following command to restart DHCP service.
Console#ip dhcp restart | |

Configuring User Authentication
Use the Passwords or Radius menu to restrict management access based on specified user names and passwords. You can manually configure access rights on the switch (Passwords menu), or you can use a remote access authentication server based on the RADIUS protocol (Radius menu).
Configuring the Logon Password
The guest only has read access for most configuration parameters. However, the administrator has write access for all parameters governing the onboard agent. You should therefore assign a new administrator password as soon as possible, and store it in a safe place. (If for some reason your password is lost, you can reload the factory default settings to restore the default password as described in “Upgrading Firmware via the Serial Port” on page
