STEP 3 Click Apply. The RADIUS default settings for the device are updated in the
Running Configuration file.
To add a RADIUS server, click Add.
STEP 4 Enter the values in the fields for each RADIUS server. To use the default values
entered in the RADIUS page, select Use Default.
• Server Definition—Select whether to specify the RADIUS server by
IP address or name.
• IPv6 Address Type—Displays that IPv6 address type is Global.
• IPv6 Address Type—Select the IPv6 address type (if IPv6 is used). The
options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
- Global—The IPv6 address is a global Unicast IPV6 type that is visible and
reachable from other networks.
• Link Local Interface—Select the link local interface (if IPv6 Address Type
Link Local is selected) from the list.
• Server IP Address/Name—Enter the RADIUS server by IP address or
name.
• Priority—Enter the priority of the server. The priority determines the order
the device attempts to contact the servers to authenticate a user. The device
starts with the highest priority RADIUS server first. Zero is the highest
priority.
Key String—Enter the key string used for authenticating and encrypting
communication between the device and the RADIUS server. This key must
match the key configured on the RADIUS server. It can be entered in
Encrypted or Plaintext format. If Use Default is selected, the device
attempts to authenticate to the RADIUS server by using the default Key
String.
• Timeout for Reply—Enter the number of seconds the device waits for an
answer from the RADIUS server before retrying the query, or switching to the
next server if the maximum number of retries were made. If Use Default is
selected, the device uses the default timeout value.
