9.1.4.2 Vendor Specific Attribute

With RADIUS 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 the following:

• 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 on the VSG, configure the

proprietary VSAs on the RADIUS server. Refer to the documentation that

comes with your RADIUS server for more information.

See Appendix D on page 242 for more information on the VSAs.
