Step Command Remarks
1. Enter system view.
system-view N/A
2. Specify a backup source IP
address for outgoing RADIUS
packets.
radius nas-backup-ip ip-address
[ vpn-instance vpn-instance-name ]
Not specified by default.
To specify a backup source IP address for a RADIUS scheme:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RADIUS scheme view.
radius scheme
radius-scheme-name
N/A
3. Specify a backup source IP
address for outgoing RADIUS
packets.
nas-backup-ip ip-address Not specified by default.
NOTE:
The backup source IP address specified for outgoing RADIUS packets takes effect only when stateful
failover is configured, and it must be the source IP address for outgoing RADIUS packets that is confi
ured
on the standby switch.
Setting timers for controlling communication with RADIUS servers
The switch uses the following types of timers to control the communication with a RADIUS server:
• Server response timeout timer (response-timeout)—Defines the RADIUS request retransmission
interval. After sending a RADIUS request (authentication/authorization or accounting request), the
switch starts this timer. If the switch receives no response from the RADIUS server before this timer
expires, it resends the request.
• Server quiet timer (quiet)—Defines the duration to keep an unreachable server in blocked state. If
a server is not reachable, the switch changes the server's status to blocked, starts this timer for the
server, and tries to communicate with another server in active state. After this timer expires, the
switch changes the status of the server back to active.
• Real-time accounting timer (realtime-accounting)—Defines the interval at which the switch sends
real-time accounting packets to the RADIUS accounting server for online users. To implement
real-time accounting, the switch must periodically send real-time accounting packets to the
accounting server for online users.
