MES3500-24/24F 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. 

Mode

The Switch supports two modes of recording login events. Select:

•

start-stop - to have the Switch send information to the accounting server when a user 

begins a session, during a user’s session (if it lasts past the Update Period), and when 

a user ends a session.

•

stop-only - to have the Switch send information to the accounting server only when a 

user ends a session. 

Method

Select whether you want to use RADIUS or TACACS+ for accounting of specific types of 
events. 

TACACS+ is the only method for recording Commands type of event. 

Privilege

This field is only configurable for Commands type of event. Select the threshold command 
privilege level for which the Switch should send accounting information. The Switch will 
send accounting information when commands at the level you specify and higher are 
executed 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.

Cancel

Click Cancel to begin configuring this screen afresh.
