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.
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
Table 65 Supported VSAs
FUNCTION ATTRIBUTE
Ingress Bandwidth
Assignment
Vendor-Id = 890
Vendor-Type = 1
Vendor-data = ingress rate (Kbps in decimal format)
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.
