Typically, a realm appears before the user field and is separated with the / character; for example, usEast/jill@abc.com. To use the realm name usEast rather than abc.com as the domain name, set the realm name delimiter to /. For example:
- host1(config)#aaa delimiter realmName /
This command causes the router to use the string to the left of the / as the domain name. If the realm name delimiter is null (the default), the router will not search for the realm name.
