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, you can shutdown the slot
blade or CP blade (if dual core switch) using this new
“BLADE_FAULT_ON_HWERRMSK” in the configure menu. Also, an external
error log message is 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.
