15.10.1 Local User Accounts
By storing user profiles locally on the system, your system is able to authenticate and authorize
users without interacting with a network authentication server. However, there is a limit on the
number of users you may authenticate in this way.
15.10.2 RADIUS and TACACS+
RADIUS and TACACS+ are security protocols used to authenticate users by means of an external
server instead of (or in addition to) an internal device user database that is limited to the memory
capacity of the device. In essence, RADIUS and TACACS+ authentication both allow you to validate
an unlimited number of users from a central location.
The following table describes some key differences between RADIUS and TACACS+.
