Length

The length region is two-octets long and is used to specify the length of a RADIUS accounting message. The value in this field is calculated by analyzing the code, identifier, length, authenticator, and attribute fields and finding their sum. The length field is checked to ensure data integrity when an accounting server receives a packet. Valid length values range between 20 and 4095.

The RFC specification requires certain behaviors of RADIUS servers with regard to incorrect length data. If the accounting server receives a transmission with a message longer than the length field, it ignores all data past the end point designated in the length field. Conversely, if the server receives a shorter message than the length field reports, the server will discard the message.
