Zone definitions are persistent. That is the definition remains in effect across
reboots and power cycles until it is deleted or changed.

A device may be a member of multiple zones.

Zone Members

Zone members may be specified using one of the following notations:

■

Node World Wide Name

■

Port World Wide Name

■

Physical Fabric port number.

A physical Fabric port number notation is specified as a pair of decimal
numbers s,p, where:

s - is the Switch number (domain ID)

p - is the Switch port number

For example, 2,12 specifies port 12 on Switch number 2. When a zone
member is specified by a physical Fabric port number, then any and all

devices

connected to that port are in the zone. If this port is an arbitrated loop,

then all loop devices are in the zone.

A World Wide Name notation (node and port) is specified as an eight hex
number separated by colons. For example 10:00:00:60:69:00:00:8a. Zoning
has no field knowledge within a World Wide Name, the eight bytes are simply
compared with the Node and Port Names presented by a device in a login
frame (FLOGI or PLOGI). When a zone member is specified by Node Name,
then all ports on that device are in the zone. When a zone member is specified
by Port Name then only that single device port is in the zone.

The type of zone members used to define a zone may be mixed and matched.
For example, a zone defined with the following members:

2,12; 2,14; 10:00:00:60:69:00:00:8a

would contain what ever devices are connected to Switch 2, ports 12 and 14,
and the device with either Node Name or Port Name of
10:00:00:60:69:00:00:8a whichever port in the Fabric it is connected to.

Zone Aliases

Zone aliases simplify repetitive port numbers entries or World Wide Names. A
zone alias is a C-style name for one or more port numbers or World Wide
