10.6 Technical Reference

This section provides technical background information about the topics covered in
this chapter.

10.6.1 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+.
