After you specify the source IP address for RADIUS packets to be sent, if the physical port for sending 

the RADIUS packets fails, response packets from the RADIUS server will be able to arrive the NAS. 

Follow these steps to specify the source IP address for RADIUS packets to be sent: 

Enter system view 

— 

In system 
view 

radius nas-ip { ip-address | 
ipv6 ipv6-address } 

radius scheme 
radius-scheme-name 

Specify the 
source IP 
address for 
RADIUS 
packets to be 
sent 

In RADIUS 
scheme view 

nas-ip { ip-address | ipv6 
ipv6-address } 

Required 

Use either approach 

By default, there is no source IP 
address specified for RADIUS 
packets and the IP address of 
the interface for sending the 
RADIUS packets will be used 
as the source IP address of the 
RADIUS packets. 

 

The setting by the nas-ip command in RADIUS scheme view is only for the RADIUS scheme, while that 

by the radius nas-ip command in system view is for all RADIUS schemes. However, the setting in 

RADIUS scheme view takes precedence over that in system view. 

 

When communicating with the RADIUS server, a device can enable the following three timers:  

z 

RADIUS server response timeout (response-timeout): If a NAS receives no response from the 

RADIUS server in a period of time after sending a RADIUS request (authentication/authorization or 

accounting request), it has to resend the request so that the user has more opportunity to obtain 

the RADIUS service. The NAS uses the RADIUS server response timeout timer to control the 

transmission interval.  

z 

Primary server quiet timer (timer quiet): If the primary server is not reachable, its state changes to 

blocked, and the device will turn to the specified secondary server. If the secondary server is 

reachable, the device starts this timer and communicates with the secondary server. After this 

timer expires, the device turns the state of the primary server to active and tries to communicate 

with the primary server while keeping the state of the secondary server unchanged. If the primary 

server has come back into operation, the device interacts with the primary server and terminates its 

communication with the secondary server.   

z 

Real-time accounting interval (realtime-accounting): This timer defines the interval for performing 

real-time accounting of users. After this timer is set, the switch will send accounting information of 

online users to the RADIUS server at the specified interval. 

Follow these steps to set timers regarding RADIUS servers:
