M4300 Intelligent Edge Series Fully Managed Stackable Switches 4. Select Security > Management Security > RADIUS > Radius Configuration. The Current Server IP Address field is blank if no servers are configured (see Configure a RADIUS Server on page 508). The switch supports up to three configured RADIUS servers. If more than one RADIUS servers is configured, the current server is the primary server. If no servers are configured as the primary server, the current server is the most recently added RADIUS server. 5. In the Source Interface list, select the interface to use for RADIUS. Possible values are as follows: • None • Routing interface • Routing VLAN • Routing loopback interface • Service Port By default, VLAN 1 is used as source interface. 6. In the Max Number of Retransmits field, specify the maximum number of times a request packet is retransmitted to the RADIUS server. The valid range is 1- 15. The default value is 4. Consider the maximum delay time when you configure the RADIUS maximum retransmit and RADIUS time-out. If multiple RADIUS servers are configured, the maximum retransmit value on each is exhausted before the next server is attempted. A retransmit does not occur until the configured time-out value on that server passed without a response from the RADIUS server. Therefore, the maximum delay in receiving a response from the RADIUS application equals the retransmit times the time-out for all configured servers. If the RADIUS request was generated by a user login attempt, all user interfaces are blocked until the RADIUS application returns a response. Manage Switch Security 506 User Manual
