20.2.4 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.
" 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.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you are
done configuring.
