Configuration Guide Configuring RADIUS
Length: Identifies the length of a whole RADIUS packet, which includes Code, Identifier, Length, Authenticator, and
Attributes. It occupies two bytes. Bytes that are beyond the Length field will be truncated. If the length of a received
packet is smaller than the value of Length, the packet is discarded.
Authenticator: Verifies response packets of the RADIUS server by a RADIUS client, which occupies 16 bytes. This field
is also used for encryption/decryption of user passwords.
Attributes: Carries authentication, authorization, and accounting information, with the length unfixed. The Attributes
field usually contains multiple attributes. Each attribute is represented in the Type, Length, Value (TLV) format. Type
occupies one byte and indicates the attribute type. The following table lists common attributes of RADIUS
authentication, authorization, and accounting. Length occupies one byte and indicates the attribute length, with the unit
of bytes. Value indicates the attribute information.
