Use the primary command to specify that a configured server should be the
primary server in the group of authentication servers which have the same
server name. Multiple primary servers can be configured for each group of
servers which have the same name. When the RADIUS client has to perform
transactions with an authenticating RADIUS server of the specified name, it
uses the primary server that has the specified server name by default. If it fails
to communicate with the primary server for any reason, it uses the backup
servers configured with the same server name. These backup servers are
identified as the "Secondary" type.
There is no primary authentication server by default.
There are no user guidelines for this command.
Use the priority command in Radius mode to specify the order in which the
servers are to be used, with 0 being the highest priority.
priority — Sets server priority level. (Range 0-65535)
