RADIUS SERVER CONFIGURATION IN CISCO ROUTER

 RADIUS SERVER  CONFIGURATION  - Authentication in cisco router

Then we enable the AAA new-model; specify the RADIUS server and a group (group name SS) to be used. Group name should match in vty login authentication configuration.

SSNETWORKX (config)# aaa new-model

SSNETWORKX (config) # aaa authentication login ss group radius local

add the RADIUS server and the key; note that the key used is the same key that was configured on the RADIUS server.

SSNETWORKX (config)#radius-server host 192.168.1.2

SSNETWORKX (config)#radius-server key 1234

To configure the same RADIUS group (SS) under the vty lines as the authentication method to be used. Where we configured AAA new module  group name (SS) same should be used here also.

SSNETWORKX (config)#line vty 0 4

SSNETWORKX (config)# login authentication SS

SSNETWORKX (config)#transport input telnet
