6.9.3.1 Radius Client Configuration
A Radius client implements a client/server mechanism enabling the switch to communicate with a central
server to authenticate users and authorize their access to the switch managed network. A Radius client is often
an embedded device since it alleviates the need to store detailed user information locally.
To configure Radius client support:
1. Select Security > Radius Server from the main menu.
2. Ensure the Configuration tab is selected.
3. Select the Clients tab from the bottom portion of the Configuration tab.
The Clients tab displays the IP address and subnet mask of the switch’s existing Radius clients.
4. To remove an existing Radius client configuration from the table of configurations available to the
switch, select the configuration and click the Delete button.
5. To create a new Radius client configuration, click the Add button at the bottom of the screen.
a. Specify the IP Address/Mask of the subnet or host authenticating with the Radius client.
b. Specify a Radius Shared Secret for authenticating the RADIUS client.
Shared secrets used to verify Radius messages (with the exception of the Access-Request
message) are sent by a Radius -enabled device configured with the same shared secret. The
shared secret is a case-sensitive string that can include letters, numbers, or symbols. Make the
shared secret at least 31 characters to protect the Radius server from brute-force attacks.
c. Refer to the Status field for the current state of the requests made from applet. This field
displays error messages if something is wrong in the transaction between the applet and the
switch.
d. Click OK to use the changes to the running configuration and close the dialog.
e. Click Cancel to close the dialog without committing updates to the running configuration
NOTE The appearance of the bottom portion of the Configuration tab differs depending
on whether Clients or Proxy Servers is selected. Select the Clients tab to
display the IP Address and Subnet Mask of existing Radius clients. Existing clients
can be modified or new clients added. For more information, see Radius Client
Configuration on page 6-75. Select the Proxy Servers tab to display the ID suffix, IP
Address and Port Number of existing Radius proxy servers. Existing servers can be
modified or new proxy servers added. For more information, see Radius Proxy
Server Configuration on page 6-76.
