198 Managing administrative domains
Figure 23 Fabric showing switch and device WWNs
Figure 24 shows the filtered view of the fabric as seen from AD3 and AD4. The switch WWNs are
converted to the NAA=5 syntax; the device WWNs and domain IDs remain the same.

Admin Domain compatibility, availability, and merging
Admin Domains maintain continuity of service for Fabric OS features, and operate in mixed-release Fabric
OS environments. High availability is supported with some backward compatibility.
When an E_Port comes online, the adjacent switches merge their AD databases. The receiving switch
accepts an AD database from the neighboring switch only if the local AD database is empty or if the new
AD database exactly matches both the defined and effective configurations of the local AD database. If the
AD database merge fails, the E_Port is segmented with AD conflict error code.
Admin Domains can be implemented in fabrics with a mix of AD-capable and non-AD-capable switches.
The following considerations apply:
AD4
WWN = 10:00:00:00:c8:3a:fe:a2
AD3
WWN = 10:00:00:00:c2:37:2b:a3
Domain ID = 2
WWN = 10:00:00:05:2e:06:34:6e
Domain ID = 1
WWN = 10:00:00:05:1f:05:23:6f
WWN = 10:00:00:00:c7:2b:fd:a3
