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, or FCoE 10-24.
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.
D-Port Parameters
Disables or enables the D_Port parameters on the switch.
Dynamic D_Port
Disables or enables Dynamic D_Port mode configuration on the switch. By
default, Dynamic D_Port mode is ON. When Dynamic D_Port mode is ON, the
port may dynamically go into D_Port mode based on external request from remote
HBA or device port. After the D_Port tests are complete, the port may
automatically switch to operate as an F_Port. This option is not supported in AG
mode.
On Demand D_Port
Disables or enables On-Demand D_Port mode configuration on the switch. By
default, On-Demand D_Port mode is OFF.
RDP Polling Cycle
Displays the Switch Driver timer routine for polling. The switch need not be
disabled to configure this variable.
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.
