RADIUS_REQ_T

Last published : Oct 30, 2026
Retrieves header information and AVPs from radius requests.
AVPs can be retrieved by:
  • Directly specifying the AVP codes in the form: radius.REQ.AVP( ). For example, to retrieve the NAS-IP-Address AVP (code 4), you can use the expression: radius.REQ.AVP(4).
  • Using aliases that are provided for important AVPs. For example, the User-Name AVP has the alias USER_NAME. So, the expression to retrieve the User-Name AVP by using the alias is radius.req.USER_NAME
General usage: radius.REQ.
This topic lists the expressions that are provided by this class.
*Note *: Expressions with the * symbol are inherited / promoted from radius_message_t
  • TYPECAST_RADIUS_MESSAGE_T
    Convert radius_req_t to radius_message_t. Will raise an undef if the value is null, empty, or the value has an invalid format for the destination type. (radius_message_t : Define common operations for radius.Req or radius.Res.)
Returns: radius_message_t
*ACCT_MULTI_SESSION_ID
Returns the Acct-Multi-Session-Id AVP (code 50) from the message.
Returns: radius_avp_t
*ACCT_SESSION_ID
Returns the Acct-Session-ID AVP (code 44) from the message.
Returns: radius_avp_t
*ACCT_STATUS_TYPE
Returns the ACCT_STATUS_TYPE AVP (code 40) from the message.
Returns: radius_avp_t
*AVP_END
Returns the location at the end of radius message (or in other words end of all AVPs) in radius message.
Returns: text_t
*AVP_LIST
Returns the AVP region in radius message (or in other words returns location at start of AVPs and length equal to radius message length excluding header).
Returns: text_t
*AVP (uint avpcode)
Returns the specified AVP from the message.
For example, to get the AVP with code 26 from a Request, use the expression: radius.REQ.AVP(26).
Parameters (expressions not allowed):
            avpcode- AVP code
Returns: radius_avp_t
*AVP (uint avpcode, uint vendorid)
Returns the specified AVP encoded within a Vendor-Specific Radius attribute with the given vendorid from the message.
For example, to get Vendor AVP 1 with vender ID '10415' from a Request, use the expression: radius.REQ.AVP(10, 10415).
Parameters (expressions not allowed):
            avpcode- AVP code
            vendorid- Vendor ID
Returns: radius_avp_t
