15.3.3 Configuring Interface for RADIUS Communication
The device can communicate with the RADIUS server through its' OAMP (default) or SIP
Control network interface. To change the interface for RADIUS traffic, use the
RadiusTrafficType parameter.
Note: If you configure the parameter to Control, make sure that only one Control
interface is configured in the IP Interfaces table (see '
Interfaces' on page 146); otherwise, RADIUS communication fails.
15.3.4 Configuring RADIUS Packet Retransmission
You can configure the device to resend packets to the RADIUS server if no response is
received from the server. This functionality is applicable to RADIUS-based user
authentication and RADIUS-based accounting.
To configure RADIUS packet retransmission:
1. Open the Authentication Server page (Setup menu > Administration tab > Web &
CLI folder > Authentication Server).
Figure 15-11: Configuring RADIUS Packet Retransmission
2. Under the RADIUS group, do the following:
1. In the 'RADIUS Packets Retransmission' field (RADIUSRetransmission), enter
the maximum number of RADIUS retransmissions that the device performs if no
response is received from the RADIUS server.
2. In the 'RADIUS Response Time Out' field (RadiusTO), enter the interval (in
seconds) that the device waits for a response before sending a RADIUS
retransmission.
3. Click Apply.
15.3.5 Configuring the RADIUS Vendor ID
The vendor-specific attribute (VSA) identifies the device to the RADIUS server using the
Vendor ID (as registered with the Internet Assigned Numbers Authority or IANA). The
device's default vendor ID is 5003 which can be changed, as described in the following
procedure. For an example of using the Vendor ID, see 'Setting Up a Third-Party RADIUS
Server' on page 251. The procedure is applicable to both RADIUS-based user
authentication and RADIUS-based accounting.
Note: The Vendor ID must be the same as the Vendor ID set on the third-party
RADIUS server. See the example for setting up a third-
'Setting Up a Third-Party RADIUS Server' on page 251.
