Default Zone; Zone Sets - HP 316095-B21 - StorageWorks Edge Switch 2/24 User Manual

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: If a managed product's Domain ID changes, you must reconfigure all zones that
contained the managed product's port as a zone member. We recommend assigning unique
Preferred Domain IDs to each switch in the fabric 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. Here are some important points to remember about

zone sets:

• 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 a
members of a zone in the active zone set are included in the default zone.
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 Table 3–1 on page 3-10
that you can configure in a zone set and the number of zone sets that you can
configure.
Here are some important points to remember about zone sets:
• If no zone set is active, and the default zone is disabled, then no devices can
communicate.
