User Guidelines
RADIUS servers are keyed by the host name/IP address, therefore it is
advisable to use unique server host names. Use the show aaa servers
{accounting|authentication} command to display the hostname/IP address
to list name mapping.
Multiple authentication servers may be configured with the same name using
the name command.
Dell EMC Networking implements a two-level hierarchy for RADIUS servers.
The top level is a list of servers which is alphabetically ordered by name. Each
server within the top level may be associated with the multiple server
hostnames/IP addresses. When multiple RADIUS servers are configured with
different names (for example, one server is name1 with address 1.1.1.1 and
the second server is name2 with address 1.1.1.2):
• 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
