RADIUS accounting with VSA
VSA stands for Vendor Specific Attributes. This VSA is a “value in bytes” sent by RADIUS server to gateway along
with an Access-Accept packet. In other words, when your external RADIUS server accepts HS1100’s request,
RADIUS not only replies with an “access-accept” but it also carries a maximum value in bytes that each client is
allowed to transfer. This value is the maximum allowable summation of each client’s download plus upload traffic in
bytes. Access-Accept packet and VSA are sent back to gateway in one session.
The bellowing shows the summary of this VSA format: (The fields are transmitted from left to right.)
