14.10.7 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 Section 14.8 on page 572) 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 for how to
configure VSAs for users authenticating via the RADIUS server.
The following table describes the VSAs supported on the system.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The system
loses these changes if it is turned off or loses power, so use the Config Save link on the
navigation panel and then the Save button to save your changes to the non-volatile memory
when you are done configuring.
