Server-Derived Role
If the client is authenticated via an authentication server, the user role for the client can be based on one or more
attributes returned by the server during authentication. You configure the user role to be derived by specifying
condition rules; when a condition is met, the specified user role is assigned to the client. You can specify more
than one condition rule; the order of rules is important as the first matching condition is applied. You can also
define server rules based on client attributes such as ESSID, BSSID, or MAC address, even though these
attributes are not returned by the server.
For information about configuring a server-derived role, see “Configuring Server-Derivation Rules” on page244.
VSA-Derived Role
Many Network Address Server (NAS) vendors, including Dell, use VSAs to provide features not supported in
standard RADIUS attributes. For Dell systems, VSAs can be employed to provide the user role and VLAN for
RADIUS-authenticated clients, however the VSAs must be present on your RADIUS server. This involves
defining the vendor (Dell) and/or the vendor-specific code (14823), vendor-assigned attribute number, attribute
format (such as string or integer), and attribute value in the RADIUS dictionary file. VSAs supported on
controllers conform to the format recommended in RFC 2865, “Remote Authentication Dial In User Service
(RADIUS)”.
Dictionary files that contain Dell VSAs are available on the Dell support website for various RADIUS servers. Log
into the Dell support website to download a dictionary file from the Tools folder.
Global Firewall Parameters
Table 58 describes optional firewall parameters you can set on the controller for IPv4 traffic. To set these options
in the WebUI, navigate to the Configuration > Advanced Services > Stateful Firewall > Global Setting page
and select or enter values in the IPv4 column. To set these options in the CLI, use the firewall configuration
commands.
See Chapter 28, “IPv6 Client Support” for information about configuring firewall parameters for IPv6 traffic.
