Zoning Concepts

Table 13-3 shows the various Brocade switch models, the hardware zoning methodology for each, and
tips for best usage.
Table 13-3 Enforcing Hardware Zoning
Fabric Type Methodology Best Practice
SilkWorm 2000-
series
Enables hardware-enforced zoning only
on domain, port zones; WWN or mixed
zones are not hardware-enforced. Any
domain, port zone that overlaps a mixed
or WWN zone is not hardware-enforced.
An overlap occurs when a member
specified by WWN is connected to a port
in a domain, port zone. The domain, port
zone loses its hardware enforcement even
though a review of the zone configuration
does not indicate it.
Use domain, port identifiers. Do not
identify a zone member by its
WWN.
SilkWorm 200E,
SilkWorm 3000-
series, SilkWorm
4100, SilkWorm
12000, 24000, and
48000 models
Enable hardware-enforced zoning on
domain, port zones, and WWN zones.
Overlap of similar zone types does not
result in the loss of hardware
enforcement. Overlap with other zone
type results in the loss of hardware
enforcement.
As in the SilkWorm 2000-series switches,
connecting a device specified by WWN
into a port specified in a domain, port
zone results in loss of the hardware
enforcement in both zones.
Use either WWN or domain, port
identifiers.
Mixed switches Enable hardware-enforced zoning
according to each switch type. Use the
portZoneShow command to find the
zone type to which a device is attached.
Use domain, port identifiers.
You can use WWN identifiers if you
place disk and tape targets on
SilkWorm 3000-series, and 12000
and 24000 models, and do not use
domain, port identifiers.
