Modify a RADIUS Configuration

About this task

Use this procedure to modify an existing RADIUS configuration or single function such as retransmissions and RADIUS accounting.

RADIUS supports IPv4 and IPv6 addresses with no difference in functionality or configuration in all except the following case. When modifying a RADIUS configuration in Enterprise Device Manager (EDM), you must specify if the address type is an IPv4 or an IPv6 address.

Procedure

  1. In the navigation pane, expand Configuration > Security > Control Path.
  2. Click RADIUS.
  3. Click the RADIUS Servers tab.
  4. In the row and field to modify, type the information or use the lists to make a selection. Access the lists by double-clicking in a field.
  5. When you are done with modifying the RADIUS configuration, click Apply.
