Appendix A. Attribute Reference

In this Appendix, the RADIUS standard attributes are listed in order by their attribute number, followed by the official name, the length of the attribute in the packet, and what type of value the attribute supports. Each attribute is then cross-referenced with the main body page explaining the details of the attribute.
