• The RADIUS request is always sent to the first server in the alphabetically ordered list of servers, for example, server name1 is attempted before moving on to the server name 2 server. Even if the priority value of hosts/IP addresses in server name 2 is lower (a lower value indicates a higher priority), the request would be sent to server name 1. If, for the server name 1, all the configured hostnames/IP addresses fail to respond, the request is sent to the second configured server. • Within a server, the primary server is always tried first. Use the primary command in RADIUS Server configuration mode to designate a primary server. One can have multiple secondary hostnames/IP addresses in the same server list. From the multiple secondary hostnames/IP addresses, the one with the lowest priority value is tried first. In a server with multiple hostnames/IP addresses with the same priority, the order of attempts is based on lexicographic order. For example, if hostnames name9, name1, name6 are configured as secondary hosts, the hostnames are attempted in the order name1, name6, name9 when the primary host fails to respond.
