RADIUS
The switch supports Remote Authorization Dial-In User Service (RADIUS) client
functionality. RADIUS has become the protocol of choice by administrators of
large accessible networks for authenticating users prior to access. To authenticate
users in a secure manner, a RADIUS client and RADIUS server are configured with
the same shared password or
secret
. This secret is used to generate one-way
encrypted authenticators that are present in all RADIUS packets. Without
knowledge of the secret, the possibility of a malicious user correctly spoofing
packets is sufficiently reduced.
The RADIUS client on the switch is used for switch management access
authentication and IEEE 802.1X (“dot1X”) port access control (see
Management
Access Profile Rules
and
802.1X
).
You can use the
RADIUS
page to configure global RADIUS settings and add
RADIUS servers.
