Vendor Specific Attribute - ZyXEL Communications MGS-3712/MES-3728 User Manual

Chapter 25 AAA

25.2.4 Vendor Specific Attribute

RFC 2865 standard specifies a method for sending vendor-specific information
between a RADIUS server and a network access device (for example, the Switch).
A company can create Vendor Specific Attributes (VSAs) to expand the
functionality of a RADIUS server.
The Switch supports VSAs that allow you to perform the following actions based
on user authentication:
• Limit bandwidth on incoming or outgoing traffic for the port the user connects
to.
• Assign account privilege levels (See the CLI Reference Guide for more
information on account privilege levels) for the authenticated user.
The VSAs are composed of the following:
• Vendor-ID: An identification number assigned to the company by the IANA
(Internet Assigned Numbers Authority). ZyXEL's vendor ID is 890.
• Vendor-Type: A vendor specified attribute, identifying the setting you want to
modify.
• Vendor-data: A value you want to assign to the setting.
Note: Refer to the documentation that comes with your RADIUS server on how to
configure VSAs for users authenticating via the RADIUS server.
The following table describes the VSAs supported on the Switch.
