Appendix D
       Vendor Specific Attributes
This appendix describes the format of the vendor specific attributes supported. 
Overview
With RADIUS server authentication, you can define vendor specific attributes (VSAs) in 
addition to the set of standard RADIUS attributes defined in RFC 2865 and RFC 2866. A VSA 
is an attribute-value pair that is sent between a RADIUS server and the VSG. It is necessary 
you define the VSAs on the RADIUS sever if you want the VSG to perform any of the 
additional functions listed below:
• Limit Download bandwidth per subscriber
• Limit Upload bandwidth per subscriber
• Limit Total traffic bandwidth allowed per subscriber 
• Specify advertising web site per subscriber 
• Enable/disable SMTP redirect  
Note: Before you can make use of these functions, configure the proprietary VSAs on 
the RADIUS server. Refer to the documentation that comes with your RADIUS server 
for more information.
