Cisco Small Business 200 Series Smart Switch Administration Guide
• Key String—Enter the default key string used for authenticating and
encrypting the RADIUS attributes communicated between the switch and
the RADIUS server. This key must match the key configured on the RADIUS
server. A key string is used to encrypt communications by using MD5. A key
configured for an individual RADIUS server has precedence over the default
key that is used if there is no key provided for an individual server.
Click Apply. The RADIUS settings for the switch are updated.
To add a RADIUS Server:
Click Security > RADIUS. The RADIUS Page displays.
Click Add. The Add RADIUS Server Page displays.
This page provides fields that must be entered individually for a server.
Enter the values in the fields for each 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.
• IP Version—If the RADIUS server will be identified by IP address, select
either IPv4 or IPv6, to indicate that it will be entered in the selected format.
• Server IP Address/Name—Address or host name of the RADIUS server.
Whether this is an IP address or host name depends on the Server Definition.
• Priority—Enter the priority of the server. The priority determines the order
the switch attempts to contact the servers to authenticate a user. The switch
will start with the highest priority RADIUS server first. Zero is the highest
priority.
• Key String—Enter the key string used for authenticating and encrypting the
RADIUS attributes communicated between the switch and the RADIUS
server. This key must match the key configured on the individual RADIUS
server. If this field is left blank, the switch attempts to authenticate to the
RADIUS server by using the default Key String.
• Timeout for Reply—Enter the number of seconds the switch waits for an
answer from the RADIUS server before retrying the query, or switching to the
next server. If there is no value entered in this field, the switch uses the
default timeout value.
