17 Administrative Domains overview Table 65 lists each Admin Domain user type and describes its administrative access and capabilities. TABLE 65 User type AD user types Description Physical fabric administrator Administrative Domain users User account with admin permissions and with access to all Admin Domains (AD0 through AD255). Creates and manages all Admin Domains. Assigns other administrators or users to each Admin Domain. The default admin account is the first physical fabric administrator. Only a physical fabric administrator can create other physical fabric administrators. Can be assigned to one or more Admin Domains. Manage the resources within their Admin Domains. If their role permits, can create user accounts and assign them to Admin Domains in their list. Cannot view other Admin Domain definitions. They can view only members of their own Admin Domains. User-defined Admin Domains AD1 through AD254 are user-defined Admin Domains. These user-defined Admin Domains can be created only by a physical fabric administrator (refer to "Admin Domain access levels" on page 435 for more information). In Figure 52 on page 434, AD1 and AD2 are user-defined Admin Domains. System-defined Admin Domains AD0 and AD255 are system-defined Admin Domains. AD0 and AD255 always exist and cannot be deleted or renamed. They are reserved for use in creation and management of Admin Domains. AD0 AD0 is a system-defined Admin Domain. Unlike user-defined Admin Domains, AD0 has an implicit and an explicit membership list. User-defined Admin Domains have only an explicit membership list. • The implicit membership list contains all devices, switch ports, and switches that have not been assigned to any other Admin Domain. Initially, the AD0 implicit membership list contains all devices, switch ports, and switches in the fabric. When you create AD1 through AD254, the devices, switch ports, and switches used to create these user-defined Admin Domains disappear from the AD0 implicit membership list. • The explicit membership list contains all devices, switch ports, and switches that you explicitly add to AD0 and can be used to force device and switch sharing between AD0 and other Admin Domains. AD0 is managed like any user-defined Admin Domain. The only difference between AD0 and user-defined Admin Domains is the implicit membership list. The implicit members of AD0 change dynamically as the membership of other Admin Domains changes. The explicit members of AD0 are not deleted unless you explicitly remove them. 436 Fabric OS Administrator's Guide 53-1002745-02
