Creating Zone Sets and Adding Member Zones
To create a zone set to include several zones, perform this task:
Tip You do not have to copy the running configuration to the startup configuration to store the active zone
set. However, you need to copy the running configuration to the startup configuration to explicitly store
full zone sets.
Note Be sure you understand how device alias modes work before enabling them. See Chapter 1, “Distributing
Device Alias Services” for details and requirements about device alias modes.
Zone Enforcement
Zoning can be enforced in two ways: soft and hard. Each end device (N port) discovers other devices in
the fabric by querying the name server. When a device logs in to the name server, the name server returns
the list of other devices that can be accessed by the querying device. If an N port does not know about
the FC IDs of other devices outside its zone, it cannot access those devices.
In soft zoning, zoning restrictions are applied only during interaction between the name server and the
end device. If an end device somehow knows the FC ID of a device outside its zone, it can access that
device.
Hard zoning is enforced by the hardware on each frame sent by an N port. As frames enter the switch,
source-destination IDs are compared with permitted combinations to allow the frame at wire speed. Hard
zoning is applied to all forms of zoning.
Command Purpose
Step 1
switch# configuration terminal
Enters configuration mode.
Step 2
switch(config)# zoneset name zoneset-name
vsan vsan-id
switch(config-zoneset)#
Configures a zone set called Zoneset1.
Tip To activate a zone set, you must first
create the zone and a zone set.
Step 3
switch(config-zoneset)# member name
Adds Zone1 as a member of the specified zone set
(Zoneset1).
Tip If the specified zone name was not
previously configured, this command will
return a “zone not present” error
message:
Step 4
switch(config-zoneset)# zone name zone-name
switch(config-zoneset-zone)#
Adds a zone to the specified zone set.
Tip Execute this step only if you need to
create a zone from a zone set prompt.
Step 5
switch(config-zoneset-zone)# member fcid
fcid
switch(config-zoneset-zone)#
Adds a new member to the new zone.
Tip Execute this step only if you need to add
a member to a zone from a zone set
prompt.
