This attribute is used when a RADIUS server acts as a proxy and needs to save information about an outstanding request, such as IP addresses, domain names, or other unique integer identifiers. There are a couple of rules to use this attribute, as specified by the RFC:

  • If the Proxy-State attribute is found in an Access-Request packet, the information must be included unmodified in the response to the packet, whether the packet is accepted, challenged, or rejected.

  • Since multiple instances of this attribute are allowed inside a packet, the order in which they are presented is relevant. When the values of the State attribute are copied, they must be copied in the order in which they were included in the original packet.

It should be noted that some RADIUS client equipment does not follow the RFC specification for the Proxy-State attribute, and this can result in the mangling of any data included in the AVP.
