Web-Based Authentication Configuring Switch-to-RADIUS-Server Communication Command or Action Purpose Step 5 address {ipv4 | ipv6} ip address Example: Device(config-radius-server)# address ipv4 10.0.1.2 auth-port 1550 acct-port 1560 Configures the IP address for the RADIUS server. Step 6 key string Example: Device(config-radius-server)# key rad123 (Optional) Specifies the authentication and encryption key used between the switch and the RADIUS daemon running on the RADIUS server. Step 7 exit Example: Device(config-radius-server)# exit Exits the RADIUS server mode and enters the global configuration mode. Step 8 radius-server vsa send authentication string Example:
Device(config)# radius-server vsa send authentication Enable downloading of an ACL from the RADIUS server. Step 9 radius-server dead-criteria[time seconds][tries num-tries] Example: Device(config)# radius-server dead-criteria tries 45 Configures the conditions that determine when a RADIUS server is considered unavailable or dead. Enter time in seconds during which there is no response from RADIUS server to the device. Enter number of tries where there will be no valid response from RADIUS server to the device. The range of num-tries is 1 to 100. Note The device will shut down if the total number of tries is set to 45 or lower when the device is part of a stack.
We recommend you to enter a longer duration of time. Higher value of number of tries prevents the device from shutting down while booting. Step 10 end Example: Exits global configuration mode and returns to privileged EXEC mode. Web-Based Authentication 16
