Configuring Ignorance Of Assigned Radius Authorization Attributes - H3C S3100 Series Operation Manual

The authentication response sent from the RADIUS server to the RADIUS client carries
authorization information. Therefore, you need not (and cannot) specify a separate RADIUS
authorization server.
In an actual network environment, you can specify one server as both the primary and secondary
authentication/authorization servers, as well as specifying two RADIUS servers as the primary and
secondary authentication/authorization servers respectively.
The IP address and port number of the primary authentication server used by the default RADIUS
scheme "system" are 127.0.0.1 and 1645.

Configuring Ignorance of Assigned RADIUS Authorization Attributes

A RADIUS server can be configured to assign multiple authorization attributes, such as authorization
VLAN and idle timeout. Some users may need the attributes but some users may not. Such conflict
occurs if the RADIUS server does not support user-based attribute assignment or it performs uniformed
user management.
The RADIUS authorization attribute ignoring function can solve this issue. It is configured as per
RADIUS scheme. Users using a RADIUS scheme with this function enabled can ignore certain
unexpected attributes.
As shown in Figure
For easy management, the RADIUS server issues the same authorization attributes to all the users.
However, users attached to NAS 1 need these attributes while users attached to NAS 2 do not want to
use the assigned Attribute 28, idle-timeout. You can configure the attribute ignoring function on NAS 2
to ignore Attribute 28.
