A Brocade Extended Fabrics license is required to set this mode.
BB Credit The buffer-to-buffer (BB) credit represents the number of buffers available to
attached devices for frame receipt. The range of allowed values varies
depending on other system settings (see Unicast-only Operation).
Insistent Domain ID Mode
When this mode is set, the switch attempts to acquire from the fabric the
domain number programmed in its "Switch Fabric Settings", failing which the
switch will segment from the fabric.
BALDE_FAULT_ON_HWERRMSK
In the case of non fatal HW ASIC data parity errors, the user will have the
ability to shutdown the slot blade or CP blade (if dual core switch) using this
new “BLADE_FAULT_ON_HWERRMSK” in the configure menu. In addition,
there will be a external error log message generated.
Virtual Channel Settings
The switch enables fine-tuning for a specific application by configuring the parameters for eight
virtual channels. The first two virtual channels are reserved for switch internal functions and are
not available for modification.
The default virtual channel settings have already been optimized for switch performance. Changing
the default values can improve switch performance but can also degrade performance. Do not
change these settings without fully understanding the effects of the changes.
The Virtual Channel Settings are as follows:
VC Priority specifies the class of frame traffic given priority for a virtual channel.
F_Port Login Parameters
Specify the F_Port login parameters to limit the number of virtual port logins. These are switch-wide
parameters applicable to all N_Port ID virtualization (NPIV) ports in the switch.
