Vendor Specific Attribute - ZyXEL Communications MSC1024G Series User Manual

16.9.6 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 system). A company can create
Vendor Specific Attributes (VSAs) to expand the functionality of a RADIUS server.
The MSC 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 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.
Refer to the documentation that comes with your RADIUS server for how to
configure VSAs for users authenticating via the RADIUS server.
The following table describes the VSAs supported on the system.
