Chapter 25 AAA

XGS-4528F User’s Guide

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. Note that these 
atrributes only work when you enable authorization (see 

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.
