ƒRADIUS 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.)

Vendor Specific Attribute	Vendor Code	Vendor Assigned	Attribute Value (the Max allowable
Number		Attribute Number	download and upload transfer for each
			client in bytes)
By RADIUS Standard	By vendor	By vendor	By local administrator
26	21920	10	0x100000

This section will guide you through a VSA configuration in your external RADIUS server. Before get started, go to or remotely connect to your external RADIUS server’s desktop.

Step 1 to 4: Run “Internet Authentication Server”, open “Remote Access Policies” and select a policy. Right click and scroll down to its properties page.
