Configuring Zones

Using Port Numbers

To identify a zone member by port number, use the domain identification number
of the managed product and the port number on that managed product. For
example:
Note:
the switch or director is set to Open Fabric 1.0 mode.
Port numbers can be 0 through n, with n representing the number of ports on the
managed product minus one. When you define a zone member by a port number,
any device attached through that port is included in the zone. A port number that
you assign as a zone member is automatically prefixed with the domain
identification number of the managed product.
The advantage of identifying a zone member by port number is that if the HBA on
an attached device fails, you don't have to identify the member with the WWN of
the replacement HBA.
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:
that 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:
88
Domain 1, Port 1
Port numbers cannot be used for zone members if the interoperability mode for
If a managed product's Domain ID changes, you must reconfigure all zones
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.
