What this chapter contains
This chapter describes about the RADIUS (Remote authentication Dial-In User Service)
authentication feature in NETA-21.
Applicability
The central RADIUS authentication feature is available from firmware version 2.30 or later.
Advantages
On a large network each NETA-21 does not need to have user accounts and passwords
defined separately for all users. Instead, with the RADIUS authentication feature, the user
accounts and password policies can be managed centrally. This helps to increase the
cyber security of the web interface.
Features
The RADIUS authentication supports two protocol variants:
• Basic/RFC2865
• EAP-TTLS (RFC5281)
