Generally, the access users are named in the userid@isp-name format. Here, isp-name after the
"@" character represents the ISP domain name, by which the device determines which ISP domain
a user belongs to. However, some old RADIUS servers cannot accept the usernames that carry
ISP domain names. In this case, it is necessary to remove domain names from usernames before
sending the usernames to RADIUS server. For this reason, the user-name-format command is
designed for you to specify whether or not ISP domain names are carried in the usernames to be
sent to RADIUS server.
For a RADIUS scheme, if you have specified to remove ISP domain names from usernames, you
should not use this RADIUS scheme in more than one ISP domain. Otherwise, such errors may
occur: the RADIUS server regards two different users having the same name but belonging to
different ISP domains as the same user (because the usernames sent to it are the same).
In the default RADIUS scheme "system", ISP domain names are removed from usernames by
default.
The purpose of setting the MAC address format of the Calling-Station-Id (Type 31) field in RADIUS
packets is to improve the switch's compatibility with different RADIUS servers. This setting is
necessary when the format of Calling-Station-Id field recognizable to RADIUS servers is different
from the default MAC address format on the switch. For details about field formats recognizable to
RADIUS servers, refer to the corresponding RADIUS server manual.

Configuring the Local RADIUS Server

The switch provides the local RADIUS server function (including authentication and authorization), also
known as the local RADIUS server function, in addition to RADIUS client service, where separate
authentication/authorization server and the accounting server are used for user authentication.
Follow these steps to configure the local RADIUS server function:
To do...
Enter system view
Enable UDP ports for local
RADIUS services
Configure the parameters of
the local RADIUS server
Use the command...
system-view
local-server enable
local-server nas-ip ip-address
key password
2-16
Remarks
Optional
By default, the UDP ports for
local RADIUS services are
enabled.
Required
By default, a local RADIUS
server is configured with an
NAS IP address of 127.0.0.1.
