subnets, be sure to specify a default gateway on the IP Setup page
(Figure 2 on page 12) so that the switch and server can communicate
with each other.
ˆ You need to configure the RADIUS software on the authentication
server. This involves the following:
– Specifying the username and password combinations. The
maximum length for a username is 38 alphanumeric
characters and spaces, and the maximum length for a
password is 16 alphanumeric characters and spaces.
– Assigning each combination an authorization level. How
this is achieved differs depending on the server software
you are using.
For RADIUS, management level is controlled by the Service Type
attribute. This attribute has 11 different values; only two apply to the
AT-S88 management software. A value of Administrative for this
attribute gives the username and password combination Manager
access. A value of NAS Prompt assigns the combination Operator
status.
Note
This manual does not explain how to configure RADIUS server
software. For that you need to refer to the documentation that came
with the software.
ˆ You must activate the RADIUS client software on the switch using the
AT-S88 management software and configure the settings. The
procedure for this step is found in this chapter.
For more information on RADIUS, refer to the RFC 2865 standard.
