Configuring Zones
A disadvantage of port zoning is that someone may rearrange cable connections to
ports (because of port failures or other reasons) and inadvertently allow devices to
communicate that should not have access to each other.
Note:
contained the managed product's port as a zone member. We recommend assigning
unique Preferred Domain IDs to each switch in the fabric. You can make these
assignments using the EWS Configure page, Switch, Parameters tabs to change the
Preferred Domain IDs.
Default Zone
A default zone consists of all devices that have not been configured as members of
a zone in a currently-active zone set. The following are some important points to
remember about zone sets:

Zone Sets
A zone set is a group of zones that you can activate or deactivate as a single entity
across all managed products in either a single switch or a multiswitch fabric. Only
one zone set can be active at one time. Devices that are members of zones in the
zone set can only communicate with members of zones in the same zone set.
However, devices can be included as members of more than one zone set. By
activating a zone set, you are making all zones in the set active.
Refer to
that you can configure in a zone set and the number of zone sets that you can
configure.

If a managed product's Domain ID changes, you must reconfigure all zones that
You can enable or disable the default zone separately from the active zone set
by choosing the Zoning option from the Configure menu. Enabling the
default zone allows all devices and ports not configured as members of the
active zone set to communicate. If the default zone is disabled, these ports and
devices cannot communicate.
When no zone set is activated, then all devices are considered to be in the
default zone.
If a zone set is active, then all connected devices that are not included as
members of a zone in the active zone set are included in the default zone.
