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 PID assignment. In either case, the WWN-based persistent PID
feature must be enabled through configure. The feature is disabled by default; 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, DCX-4S, DCX 8510-8, and
DCX 8510-4 the switch cannot be a default switch or include interchassis link
(ICL) ports. This feature is enabled by default (yes=enabled). On the Brocade
5100, 5300, VA-40FC, and 6510 default switch, the feature is disabled by default
(no=disabled). Beginning with Fabric OS v7.0.0, the XISL feature is supported on
the Brocade extension blade (FX8-24).
You do not need to disable 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. The Brocade 7800 VF configuration
does not support XISL usage and therefore this option is not available on this
logical switch.
Disable FID Check
If fabric ID (FID) check is disabled, the fabric ignores the Fabric Identifier conflict
with the neighboring switch during fabric formation. By default, FID check is
enabled. If the fabric detects a FID conflict, it disables the E_Port with a "Fabric ID
conflict" message. This parameter is configurable only if the switch is Virtual
Fabric-aware and Virtual Fabric is enabled on the switch.
Enable 256 Area limit
The 256 area limit allows the partition to be configured for 8-bit addressing rather
than the default 10-bit addressing. Each port in this partition is given a unique
area represented by the middle 8 bits of the PID. Valid values include the
following:
0
No limit is imposed on the area. This is the default value. The partition is
configured for 10-bit addressing and supports up to 1800 ports.
1
The unique area assignments begin at zero regardless of where the port is
physically located. This allows FICON users to make use of high port count port
blades with port indexes greater than 256.
2
The unique area assignments are based on the port index. This mode does not
allow FICON users to make use of ports with an index greater than 256 (high ports
of a high port count blade), but this mode is compatible with domain-index zoning.
This parameter is configurable only if the switch is Virtual Fabric-aware and Virtual
Fabric is enabled on the switch.
