Fabric setting fields are defined as follows:
Domain The domain number uniquely identifies a switch in a fabric. This value is
automatically assigned by the fabric. The range of valid values varies
depending on the switch model and other system parameter settings.
Enable 8-bit Dynamic Area Mode
When enabled, this feature supports Dynamic Area Mode in default partitions
on the Brocade DCX and DCX-4S. Dynamic Area Mode is by default disabled.
When enabled, Dynamic Area Mode supports both static and dynamic area
assignment. Use the portAddress command to perform a static assignment
of an area to a given port. In Dynamic Area Mode, areas are dynamically
assigned to the ports (up to a 255 limit). Port area assignments are
persistent; however, disabling Dynamic Area Mode with configure resets the
area assignments. This feature is configurable only on the default switch.
Enabling Dynamic Area Mode fails under one or more of the following
conditions:
• The number of ports in the default partition exceeds 255.
• An AP blade with FL ports is present in the chassis (Brocade Encryption
blade, FA-418, or FCoE10-24.
• The stand-by CPU is running a pre-v6.4.0 version of Fabric OS.
WWN Based persistent PID
When enabled, this feature supports both dynamic and static WWN-based
PID assignment. In dynamic PID binding, the first area assigned to a device
when it logs in is bound to the device WWN and remains persistent through
subsequent logins. Every time the device logs into the switch, it is guaranteed
to get the same PID. Alternately, you can use the wwnAddress command to
create a static WWN-based PIDassignment. In either case, the WWN-based
persistent PID feature must be enabled through configure. The feature is by
default disabled; it is dependent on Dynamic Area Mode being enabled.
Allow XISL Use An extended interswitch link (XISL) is an interswitch link (ISL) that connects
the logical switch to the base switch and carries traffic for multiple logical
fabrics. This feature is supported only on Virtual Fabric-aware platforms
under the following conditions: Virtual Fabrics must be enabled on the switch,
and the switch cannot be a base switch. In addition, on the Brocade DCX or
DCX-4S the switch cannot be a default switch, include interchassis link (ICL)
ports or GbE ports, or be in interop mode. This feature is enabled by default
(yes=enabled). On the Brocade 5100, 5300, and VA-40FC default switch, the
feature is disabled by default (no=disabled).
Fabric OS v6.3.0 and later no longer require disabling the logical switch
before changing the value of this parameter. Turning off XISL use requires
confirmation because all LISLs will be removed upon execution. If the logical
switch is enabled and is part of an edge fabric connected to an FCR, this
parameter cannot be turned on. If the logical switch is disabled or it is not yet
part of an edge fabric, this parameter can be turned on. However, execution
may cause edge fabric segmentation if the EX_Port connected to the edge
fabric is disabled while the logical switch is enabled or connected to the edge
fabric.
