lists the differences between zones and VSANs.
A zone consists of multiple zone members.
–
Members in a zone can access each other; members in different zones cannot access each other.
–
If zoning is not activated, all devices are members of the default zone.
–
If zoning is activated, any device that is not in an active zone (a zone that is part of an active
zone set) is a member of the default zone.
–
Zones can vary in size.
Devices can belong to more than one zone.
–
A zone set consists of one or more zones.
A zone set can be activated or deactivated as a single entity across all switches in the fabric.
–
Only one zone set can be activated at any time.
–
A zone can be a member of more than one zone set.
–
Zoning can be administered from any switch in the fabric.
–
When you activate a zone (from any switch), all switches in the fabric receive the active zone
set. Additionally, full zone sets are distributed to all switches in the fabric, if this feature is
enabled in the source switch.
If a new switch is added to an existing fabric, zone sets are acquired by the new switch.
–
Zone changes can be configured nondisruptively. New zones and zone sets can be activated without
interrupting traffic on unaffected ports or devices.
Zone membership criteria is based on WWNs or FC IDs.
–
Port world wide name (pWWN)—Specifies the pWWN of an N port attached to the switch as a
member of the zone.
–
Fabric pWWN—Specifies the WWN of the fabric port (switch port's WWN). This membership
is also referred to as port-based zoning.
FC ID—Specifies the FC ID of an N port attached to the switch as a member of the zone.
–
–
Interface and switch WWN (sWWN)—Specifies the interface of a switch identified by the
sWWN. This membership is also referred to as interface-based zoning.
–
Interface and domain ID—Specifies the interface of a switch identified by the domain ID.
–
Domain ID and port number—Specifies the domain ID of an MDS domain and additionally
specifies a port belonging to a non-Cisco switch.
–
IP address—Specifies the IP address (and optionally the subnet mask) of an attached device.
Default zone membership includes all ports or WWNs that do not have a specific membership
association. Access between default zone members is controlled by the default zone policy.
You can configure up to 2000 zones per VSAN and a maximum of 2000 zones for all VSANs on the
switch.
