When multiple RADIUS servers are configured with different names, the servers are in different groups. The primary/secondary designation and priority applies to RADIUS servers only within the same group. Within a named group, the switch always attempts to contact the primary RADIUS server first. When two or more groups have been configured, the switch determines which named group to contact first based on lexicographic order (alphabetical) order. For example, an administrator configures the following two RADIUS servers in this order: • Server Name is name1 and address is 1.1.1.1 • Server Name is name2 and address is 1.1.1.2 In this example, the switch has two configured authentication servers. Because the name for each server is unique, the switch has two named authentication server groups. The switch always attempts to contact the name1 server before moving on to name2. Even if the configured priority value of the name2 server is lower (lower value indicates higher priority), the request would be sent to the name1 servers. The request is sent to the name2 server only if the name1 server fails to respond. To provide additional redundancy, the administrator can configure additional servers within the named groups, for example: • Server name is name1 and address is 1.1.1.3 • Server name is name1 and address is 1.1.1.4 • Server name is name 2 and address is 1.1.1.5 Now, the name1 server group includes three configured RADIUS servers, and the name2 group has two servers. The administrator can configure the primary/secondary status and priority within each group to control which server is tried first. Between the two secondary servers, the one with lowest priority value is tried if the primary server cannot be contacted. The RADIUS servers in the name2 group are contacted only if no servers in the name1 group can be reached. If an additional servers are configured in a group named abc, the primary server in the abc group is contacted first because lexicographically, abc comes before name1.
