3Com 4500G Family Configuration Manual page 570

For the NAS, each user belongs to an ISP domain. A NAS can accommodate up to 16 ISP domains,
including the default ISP domain named system. If a user does not provide the ISP domain name, the
system considers that the user belongs to the default ISP domain.
Follow these steps to create an ISP domain:
To do...
Enter system view
Create an ISP domain and
enter ISP domain view
Return to system view
Specify the default ISP domain
You cannot delete the default ISP domain unless you change it to a non-default ISP domain (with
the domain default disable command) first.
If a user enters a username without an ISP domain name, the device uses the authentication
method configured for the default ISP domain to authenticate the user.
