Resolving Zone Conflicts
13
After examining the configuration file, you can choose to resolve zone conflicts by using the cfgClear
command followed by the cfgDisable command on the incorrectly configured segmented fabric,
followed by a portDisable/portEnable command on one of the ISL ports that connects the fabrics. This
will cause a merge, making the fabric consistent with the correct configuration.
Table 13-9 lists considerations for zoning architecture.

Be careful using the cfgClear command, because it deletes the defined configuration.
Table 13-9 Considerations for Zoning Architecture
Item Description
Type of zoning: hard or
soft (session-based)
If security is a priority, hard zoning is recommended.
Use of aliases The use of aliases is optional with zoning. Using aliases requires
structure when defining zones. Aliases will aid administrators of
zoned fabric in understanding the structure and context.
Security requirements Evaluate the security requirements of the fabric. If additional
security is required, add Brocade Secure Fabric OS into the fabric.
Interoperability Fabric If the fabric includes a third-party switch product, only WWN
zoning is supported. Other types of zoning, including QuickLoop,
are not supported.
QLFA zones Evaluate if the fabric will have QuickLoop Fabric Assist (QLFA)
or QuickLoop (QL) in it, and consider the following items before
creating and setting up QLFA zones:
QuickLoop Zoning—QuickLoop/QuickLoop zones cannot run on
Fabric OS v4.1.0 or later. However, Fabric OS can manage (create,
remove, update) QL zones.
QuickLoop Fabric Assist—A switch running Fabric OS v4.1.0 or
later cannot have a Fabric Assist host directly connected to it.
However, such a switch can be part of a Fabric Assist zone if a
Fabric Assist host is connected to a compatible switch in
the fabric.
Testing Testing a (new) zone configuration. Before implementing a zone,
the user should run the Zone Analyzer from Web Tools to isolate
any possible problems. This is especially useful as fabrics increase
in size.
