Domain IDs Domain IDs uniquely identify a switch in a VSAN. A switch may have different domain IDs in different VSANs. The domain ID is part of the overall FC ID. This section describes how to configure domain IDs and includes the following topics: • About Domain IDs, page 25-8 • Specifying Static or Preferred Domain IDs, page 25-10 • About Allowed Domain ID Lists, page 25-11 • Configuring Allowed Domain ID Lists, page 25-11 • About CFS Distribution of Allowed Domain ID Lists, page 25-12 • Enabling Distribution, page 25-12 • Locking the Fabric, page 25-13 • Committing Changes, page 25-13 • Discarding Changes, page 25-13 • Clearing a Fabric Lock, page 25-14 • Displaying Pending Changes, page 25-14 • Displaying Session Status, page 25-14 • About Contiguous Domain ID Assignments, page 25-15 • Enabling Contiguous Domain ID Assignments, page 25-15 About Domain IDs The configured domain ID can be preferred or static. By default, the configured domain ID is 0 (zero) and the configured type is preferred. Note The 0 (zero) value can be configured only if you use the preferred option. If you do not configure a domain ID, the local switch sends a random ID in its request. We recommend that you use static domain IDs. When a subordinate switch requests a domain, the following process takes place (see Figure 25-7): 1. The local switch sends a configured domain ID request to the principal switch. 25-8 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
