Netgear M5300-28G-POE+ (GSM7228PSv1h2) - 12-Port Managed Gigabit Switch Softwarehandbuch

This section describes the commands you use to add, manage, and delete system users. 
NETGEAR Managed Switch software has two default users: admin and guest. The admin 
user can view and configure system settings, and the guest user can view settings. 

You cannot delete the admin user. There is only one user allowed with 
read/write privileges. You can configure up to five read-only users on 
the system.

Use this command to set authentication at login. The default and optional list names created 
with the command are used with the aaa authentication login command. Create a list 
by entering the aaa authentication login list-name method command, where 
list-name

 is any character string used to name this list. The method argument identifies 

the list of methods that the authentication algorithm tries, in the given sequence.

The additional methods of authentication are used only if the previous method returns an 
error, not if there is an authentication failure. To ensure that the authentication succeeds 
even if all methods return an error, specify none as the final method in the command line. 
For example, if none is specified as an authentication method after radius, no 
authentication is used if the RADIUS server is down.

If you configure local as the first method in the list, the switch tries no other methods.

Default
