Authentication When Radius Servers Do Not Respond - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

Natasha also enables backup RADIUS authentication for Telnet administrative users. If the RADIUS
server does not respond, the user is authenticated by the local database in the switch. Natasha types
the following commands:
DWS-1008# set authentication admin * sg1 local
success: change accepted.
DWS-1008# save config
success: configuration saved.
The order in which Natasha enters authentication methods in the set authentication command
determines the method MSS attempts first. The local database is the first method attempted for console
users and the last method attempted for Telnet administrators.

Authentication When RADIUS Servers Do Not Respond

This scenario illustrates how to enable RADIUS authentication for both console and administrative
users, but to unconditionally allow access for administrative and console users if the RADIUS server (in
this case, server r1 in server group sg1) does not respond. To configure unconditional authentication,
Natasha sets the authentication method to none. She types the following commands in this order:
DWS-1008# set user natasha password m@Jor
User natasha created
DWS-1008# set radius server r1 address 192.168.253.1 key sunFLOW#$
success: change accepted.
DWS-1008# set server group sg1 members r1
success: change accepted.
DWS-1008# set authentication console * sg1 none
success: change accepted.
DWS-1008# set authentication admin * sg1 none
success: change accepted.
DWS-1008# save config
success: configuration saved.
