Zones
A zone is a named group of ports or devices that can communicate with each 
other. Devices within a zone can only communicate with other devices in the same 
zone. A device may participate in more than one zone. 
Membership in a zone can be defined by switch domain ID and port number, 
device Fibre Channel address (FCID), or device World Wide Name (WWN).
„
WWN entries define zone membership by the World Wide Name of the 
attached device. With this membership method, you can move WWN 
member devices to different switch ports in different zones without having to 
edit the member entry as you would with a domain ID/port number member. 
Furthermore, unlike FCID members, WWN zone members are not affected 
by changes in the fabric that could change the Fibre Channel address of an 
attached device.
„
FCID entries define zone membership by the Fibre Channel address of the 
attached device. With this membership method you can replace a device on 
the same port without having to edit the member entry as you would with a 
WWN member.
„
Domain ID/Port number entries define zone membership by switch domain 
ID and port number. All devices attached to the specified port become 
members of the zone. The specified port must be an F_Port or an FL_Port.
The SANbox 1400 Series switch supports soft zones and Access Control List 
(ACL) hard zones.
3.6.1.1.1
Soft Zones
Soft zoning divides the fabric for purposes of controlling discovery. Devices within 
the same soft zone automatically discover and communicate freely with all other 
members of the same zone. The soft zone boundary is not secure; traffic across 
soft zones can occur if addressed correctly. The following rules apply to soft 
zones:
„
Soft zones that include members from multiple switches need not include 
the ports of the inter-switch links.
„
Soft zones can overlap; that is, a device can participate in more than one 
soft zone.
„
Do not create a soft zone that shares membership with a hard zone. Soft 
zone members that are in the hard zone will not be able to transfer I/O with 
soft zone members that are outside of the hard zone.
„
Zone membership can be defined by Fibre Channel address, domain ID and 
port number, World Wide Name, or a combination.
„
Soft zoning supports all port types.
