    RADIUS and Diameter Transports

    To support RADIUS accounting and authentication, you need to configure both inbound and outbound transports for the SIC group and each SIC server within the group.

    To support dynamic authorization requests, you need to configure the RADIUS dynamic authorization transport as well as the Diameter transport to the Diameter server in SRC.

    Inbound and Outbound RADIUS Accounting Transports for the SIC Group

    To support RADIUS accounting in the SIC group, you need to configure the inbound transport by configuring the accounting listeners. You need to configure the group RADIUS outbound accounting transport if you are using the proxy accounting method, or if you are using implicit routing to forward accounting messages to a remote AAA server accounting target.

    Inbound and Outbound RADIUS Authentication Transports for the SIC Group

    To support RADIUS authentication in the SIC group, you need to configure the inbound transport by configuring the authentication listeners. You also need to configure the outbound RADIUS group authentication transport to the downstream AAA server authentication target.

    SIC Server Inbound and Outbound RADIUS Transports

    You can configure the inbound and outbound transport for each server in the SIC group. To do this, you specify the names you configured for the group inbound transport (authentication and accounting clients) and the group outbound transport and then specify the IP address the server used to send and receive UDP messages. This is optional. If it is not configured, the address for inbound transport is all IP addresses configured on the C Series Controller. If the address for the outbound transport is not configured, the SIC allows the SRC software to choose one from the list of addresses configured on the local machine.

    Diameter Transport

    You must configure bidirectional transport (Diameter connection) between an SIC server and the SRC Diameter server.

    For the SIC server, you specify the origin-host, origin-realm, transport protocol (TCP or SCTP), and the port the SIC server uses for Diameter messages.

    The SRC Diameter server must be defined within a network element. You need to specify the network element ID and the associated failover policy, as well as peer information for the SIC server including IP address, protocol (TCP or SCTP), and port. In addition, you must specify whether or not the peer is an active peer and the priority. These options are used when you have multiple connections from the Diameter server to multiple SIC servers (peers).
