RADIUS authentication To configure a RADIUS server for authentication, enter the server's IP address or host name. You can change the UDP port number on the server and the key used to authenticate the OS10 switch on the server. • Configure a RADIUS authentication server in CONFIGURATION mode. By default, a RADIUS server uses UDP port 1812; the switch uses radius_server as the key to log in to a RADIUS server. radius-server host {hostname | ip-address} [auth-port port-number ] Re-enter the radius-server host command multiple times to configure more than one RADIUS server. If you configure multiple RADIUS servers, OS10 attempts to connect in the order you configured them. An OS10 switch connects with the configured RADIUS servers one at a time, until a RADIUS server responds with an accept or reject response. Configure global settings for the timeout and retransmit attempts allowed on RADIUS servers by using the radius-server retransmit and radius-server timeout commands. By default, OS10 supports three RADIUS authentication attempts and times out after five seconds. • Configure the number of times OS10 retransmits a RADIUS authentication request in CONFIGURATION mode (0 to 100 retries; default 3). radius-server retransmit retries • Configure the timeout period used to wait for an authentication response from a RADIUS server in CONFIGURATION mode (0 to 1000 seconds; default 5). radius-server timeout seconds Configure RADIUS server OS10(config)# radius-server host 1.2.4.5 OS10(config)# radius-server retransmit 10 OS10(config)# radius-server timeout 10 View RADIUS server configuration OS10# show running-configuration ... radius-server host 1.2.4.5 radius-server retransmit 10 radius-server timeout 10 ... Delete RADIUS server OS10# no radius server host 1.2.4.5 RADIUS server settings Configure global communication parameters for RADIUS servers. If you configure both global and specific host parameters, the specific host parameters override the global parameters for a RADIUS server host. 1 Configure the number of times OS10 retransmits RADIUS requests in CONFIGURATION mode (0 to 100, default 3). radius-server retransmit retries 2 Configure the time interval in seconds OS10 waits for a RADIUS server host response in CONFIGURATION mode (0 to 1000, default 5). radius-server timeout seconds System management 353
