How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

To delete the specified RADIUS server, use the no radius-server host {hostname | ip-address}

command in global configuration mode.

To configure the timeout, retransmission, and encryption key values for all RADIUS servers, use the

radius-server host command in global configuration mode. To configure these options on a per-server

basis, use the radius-server timeout, radius-server retransmit, and radius-server key commands in

global configuration mode.

You also need to configure some settings on the RADIUS server. These settings include the IP address

of the switch and the key string to be shared by both the server and the switch. For more information,

refer to the RADIUS server documentation.

Enabling Periodic Reauthentication

You can enable periodic 802.1x client reauthentication and specify how often it occurs. If you do not

specify a time period before enabling reauthentication, the time between reauthentication attempts is

3600 seconds.

Automatic 802.1x client reauthentication is a global setting and cannot be set for clients connected to

individual ports.

Beginning in privileged EXEC mode, follow these steps to enable periodic reauthentication of the client

and to configure the number of seconds between reauthentication attempts.
