Configuring Administrator Usernames and Passwords

Using the CLI to Configure DHCP Proxy

Using the controller CLI, follow these steps to configure DHCP proxy.

Step 1 To enable or disable DHCP proxy, enter this command:

config dhcp proxy {enable | disable}

Step 2 To view the DHCP proxy configuration, enter this command:

show dhcp proxy

Information similar to the following appears:

DHCP Proxy Behaviour: enabled

Configuring Administrator Usernames and Passwords

Note The controller does not have a password recovery mechanism. If you use WCS to manage the controller,

you should be able to access the controller from WCS and create a new admin user without logging into

the controller itself. If you have not saved the configuration on the controller after deleting the user, then

rebooting (power cycling) the controller should bring it back up with the deleted user still in the system.

If you do not have the default admin account or another user account with which you can log in, your

only option is to default the controller to factory settings and reconfigure it from scratch or reload the

previously saved configuration.

You can configure administrator usernames and passwords to prevent unauthorized users from

reconfiguring the controller and viewing configuration information.

On the CLI, enter config mgmtuser add username password read-write to create a username-password

pair with read-write privileges. Enter config mgmtuser add username password read-only to create a

username-password pair with read-only privileges. Usernames and passwords are case-sensitive and can

contain up to 24 ASCII characters. Usernames and passwords cannot contain spaces.

To change the password for an existing username, enter

config mgmtuser password username new_password

To list configured users, enter show mgmtuser.

Configuring RADIUS Settings

If you need to use a RADIUS server for accounting or authentication, follow these steps on the CLI to

configure RADIUS settings for the controller:

Step 1 Enter config radius acct ip-address to configure a RADIUS server for accounting.

Step 2 Enter config radius acct port to specify the UDP port for accounting.

Step 3 Enter config radius acct secret to configure the shared secret.
