Usage Guidelines	To use this command, you must be in a user group associated with a task group that includes the proper

Use the server command to associate a particular RADIUS server with a defined server group.

There are two different ways in which you can identify a server, depending on the way you want to offer AAA services. You can identify the server simply by using its IP address, or you can identify multiple host instances or entries using the optional auth-portand acct-portkeywords.
