Chapter 23 Authentication & Accounting

ES-3148 User’s Guide

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 IEEE 802.1x 
authentication. The port VLAN settings are fixed and untagged. This will also set the port’s 
VID. The following table describes the values you need to configure. Note that the bolded 
values in the table are fixed values as defined in RFC 3580. 

Remote Authentication Dial-In User Service (RADIUS) attributes are data used to define 
specific authentication, and accounting elements in a user profile, which is stored on the 
RADIUS server. This appendix lists the RADIUS attributes supported by the Switch.
Refer to RFC 2865 for more information about RADIUS attributes used for authentication. 
Refer to RFC 2866 and RFC 2869 for RADIUS attributes used for accounting.
This appendix lists the attributes used by authentication and accounting functions on the 
Switch. In cases where the attribute has a specific format associated with it, the format is 
specified.

Egress Bandwidth 

Assignment

Vendor-Id = 890 
Vendor-Type = 2 
Vendor-data = 

egress rate (Kbps in decimal format) 

Privilege Assignment 

Vendor-ID = 890 
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. 

Table 66   Supported VSAs 

Table 67   Supported Tunnel Protocol Attribute

VLAN Assignment

Tunnel-Type = VLAN(13)
Tunnel-Medium-Type = 802(6)
Tunnel-Private-Group-ID = 

VLAN ID 

Note: You must also create a VLAN with the specified VID on 

the Switch.
