Chapter 23 Authentication & Accounting

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 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.

Table 65 Supported VSAs

FUNCTION

ATTRIBUTE

 

 

Ingress Bandwidth

Vendor-Id = 890

Assignment

Vendor-Type = 1

 

Vendor-data = ingress rate (Kbps in decimal format)

Egress Bandwidth

Vendor-Id = 890

Assignment

Vendor-Type = 2

 

Vendor-data = egress rate (Kbps in decimal format)

Privilege

Vendor-ID = 890

Assignment

Vendor-Type = 3

 

Vendor-Data = "shell:priv-lvl=N"

 

or

 

Vendor-ID = 9 (CISCO)

 

Vendor-Type = 1 (CISCO-AVPAIR)

 

Vendor-Data = "shell:priv-lvl=N"

 

where N is a privilege level (from 0 to 14).

 

Note: If you set the privilege level of a login account differently

 

on the RADIUS server(s) and the Switch, the user is

 

assigned a privilege level from the database (RADIUS or

 

local) the Switch uses first for user authentication.

23.2.5 Tunnel Protocol Attribute

You can configure tunnel protocol attributes on the RADIUS server (refer to your RADIUS server documentation) to assign a port on the Switch to a VLAN based on
