Home Admin Domains and login

You are always logged in to an Admin Domain, and you can view and modify only the devices in that

Admin Domain.

If you have access to more than one Admin Domain, one of them is designated as your home

Admin Domain, the one you are automatically logged in to. If your home Admin Domain is deleted

or deactivated, then by default you are logged in to the lowest-numbered active Admin Domain in

your Admin Domain list. The home Admin Domain, like the Admin Domain list, is a configurable

property of a non-default user account. Here is some additional information about AD accounts:

• You can log in to only one Admin Domain at a time. You can later switch to a different Admin

Domain (refer to “Switching to a different Admin Domain context” on page 362 for

instructions).

• For default accounts such as admin and user, the home Admin Domain defaults to AD0 and

cannot be changed.

• The Admin Domain list for the default admin account is 0 through 255, which gives this

account automatic access to any Admin Domain as soon as the domain is created, and makes

this account a physical fabric administrator.

• The Admin Domain list for the default user account is AD0 only.

• For user-defined accounts, the home Admin Domain defaults to AD0 but an administrator can

set the home Admin Domain to any Admin Domain to which the account is given access.

• If you are in any Admin Domain context other than AD0, the Admin Domain number is included

in the system prompt displayed during your session. The following are example prompts for

when you are in the AD0, AD1, and AD255 contexts, respectively:

switch:admin>

switch:AD1:admin>

switch:AD255:admin>
