Chapter 15 Configuring and Managing Zones

Setting Default Zone Policy

Each VSAN contains a default zone, which by default, contains all connected devices assigned to the
VSAN.
You can change the default zone policy for any VSAN by choosing VSANxxx > Default Zone from the
Fabric Manager menu tree and clicking the Policies tab. However, we recommend that you establish
connectivity among devices by assigning them to a nondefault zone.
The active zone set is shown in italic type. After you have made changes to the active zone set and before
you activate the changes, the zone set is shown in boldface italic type. The tooltip for each zone indicates
the activation time or modification time.

Changing the Default Zone Policy

Each member in the fabric can belong to any zone. If a member does not belong to any zone, it is part
of the default zone. If no zone has been activated in the fabric, all members belong to the default zone.
Even though a member can belong to multiple zones, a member in the default zone cannot be part of any
other zone.
Traffic can be permitted and denied to members in the default zone. This information is not distributed
to all switches. Permission and denial must be set for each switch in the fabric.
To permit or deny traffic to members in the default zone from the Zone Server, follow these steps:
Choose VSANxxx > Default Zone from the Fabric Manager menu tree, and click the Policies tab. The

isolated when the active zone set databases are different between the two switches or fabrics. (See
