AAA Security Configuration
This page lets you configure the AAA (Authentication, Authorization and Accounting) Servers. You can
configure the optional RADIUS and/or servers from the
Configuration
>
Security
>
AAA
menu path.
RADIUS (
Remote Authentication Dial In User Service) networking protocol provides centralized access,
authorization and accounting management for computers to connect and use a network service. RADIUS
is a client/server system that keeps the authentication information for users, remote access servers, VPN
gateways, and other resources in one central database.
(Terminal Access Controller Access Control System Plus) networking protocol provides
access control for routers, network access servers and other networked computing devices via one or
more centralized servers. provides separate authentication, authorization and accounting
services.
Caution
: Before enabling
RADIUS
or
, make sure that the related AAA server is operational
and that at least the AAA server's IP address/hostname and encryption/decryption parameters are set
correctly. Make sure using the following safe method:
1. Open a CLI session.
2. Enter the command "
security aaa con
".
3. Try to open a TELNET session.
Now, if the attempt fails (possibly because of an incorrect AAA parameter setting) access to the CLI agent
is retained (via the CLI session) and any AAA parameter setting can be corrected in the CLI session.
Note that “RADIUS-Assigned QoS” and “RADIUS-Assigned VLAN” can be enabled and disabled on a
per-port basis on the Network Access Server Configuration page via the
Configuration
