The portions of the TACACS packet are defined as follows:

•

Major Version

: The major version number.

•

Minor version

: The minor  version number. This is intended to allow 

revisions to the  protocol while maintaining backwards compatibility.

•

Packet type

: Possible values are:

• TAC_PLUS_AUTHEN:= 0x01 (authentication)

TAC_PLUS_AUTHOR:= 0x02 (authorization)
TAC_PLUS_ACCT:= 0x03 (accounting) 

•

Sequence number

: The sequence number of the current packet for the current 

session.

•

Flags

: This field contains various flags in the form of bitmaps. The flag values 

signify whether the packet is encrypted.

•

Session ID

: The ID for this  session.

•
