Setting Timers Regarding Radius Servers - 3Com 4500G Family Configuration Manual

Some earlier RADIUS servers cannot recognize usernames that contain an ISP domain name. In
this case, the device must remove the domain name before sending a username including a
domain name. You can configure the user-name-format without-domain command on the
device for this purpose.
If a RADIUS scheme defines that the username is sent without the ISP domain name, do not apply
the RADIUS scheme to more than one ISP domain, thus avoiding the confused situation where the
RADIUS server regards two users in different ISP domains but with the same userid as one.
The unit of data flows sent to the RADIUS server must be consistent with the traffic statistics unit of
the RADIUS server. Otherwise, accounting cannot be performed correctly.
The nas-ip command in RADIUS scheme view is only for the current RADIUS scheme, while the
radius nas-ip command in system view is for all RADIUS schemes. However, the nas-ip
command in RADIUS scheme view takes precedence over the radius nas-ip command.

Setting Timers Regarding RADIUS Servers

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