(usr-tc) hiperarc radius settings

Whats the hiperarc command to set the primary and secondary radius servers? Also is there a way to set more than two? Perhaps if there was a way to specify a hostname (not just an IP) you could set up a round robin list of IP's to it.. - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
