Admin Domain management for physical fabric administrators 15
1. Log in to the switch with the appropriate RBAC role.
2. Ensure you are in the AD0 context by entering the ad --show command to determine the
current Admin Domain.
If necessary, switch to the AD0 context by entering the ad --select 0 command.
3. Set the default zoning mode to No Access, as described in “Setting the default zoning mode”
on page 252.

Creating an Admin Domain

To create an Admin Domain, you must specify an Admin Domain name, number, or both:
•If you create an Admin Domain using only a number, the Admin Domain name is automatically
assigned to be “ADn”, where n is the number you specified.
For example, if you specify AD number = 4, then AD name is set to “AD4”.
•If you create an Admin Domain using only a name, the Admin Domain number is automatically
assigned and is the lowest available AD number, except if you specify a name in the format
“ADn”, in which case the Admin Domain number is assigned to be n.
For example, if you specify AD name = “blueAD” and the lowest available AD number is 5, then
AD name is “blueAD” and AD number is 5.
If you specify AD name = “AD15” and the lowest available AD number is 6, then AD name is
“AD15” and AD number is 15. Because the specified name is in the format “ADn”, the AD
number is assigned to be n and not the lowest available AD number.
The Admin Domain name cannot exceed 63 characters and can contain alphabetic and numeric
characters. The only special character allowed is an underscore ( _ ).
When you create an Admin Domain, you must specify at least one member (switch, switch port, or
device). You cannot create an empty Admin Domain. For more information about these member
types, see “Admin Domain member types” on page 341.
A newly created Admin Domain has no zoning defined and the default access mode is No Access.
This means the devices in the Admin Domain cannot communicate with each other. You must set
up zones in the newly created Admin Domain to allow devices to access each other, even if the
devices were already zoned together prior to your moving them to the Admin Domain. See “Admin
Domains, zones, and zone databases” on page 360 for additional information about how zones
work with Admin Domains.
You create Admin Domains in the transaction buffer. You can either save the newly created Admin
Domain to a defined configuration or make it the effective Admin Domain configuration directly.
The following procedure describes the steps for creating Admin Domains.
1. Log in to the switch as the physical fabric administrator.
2. Disable Virtual Fabrics, if necessary, as described in “Disabling Virtual Fabrics mode” on
page 224. Admin Domains and Virtual Fabrics cannot co-exist.
3. Set the default zone mode to No Access, if you have not already done so. See “Setting the
default zoning mode” on page 252 for instructions.
4. Switch to the AD255 context, if you are not already in that context:
ad --select 255
