Configuring virtual channel settings
You can configure parameters for eight virtual channels (VC) to enable fine-tuning for a specific
application. You cannot modify the first two virtual channels, which are reserved for switch internal
functions.
ATTENTION
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.
VC Priority specifies the class of frame traffic given priority for a virtual channel.
1. Open the Switch Administration window as described on page 29.
2. Disable the switch as described on page 34.

Disable Device Probing Set this mode only if the switch N_Port discovery process (PLOGI, PRLI, INQUIRY) causes
an attached device to fail. When set, devices that do not register with the Name Server are
not present in the Name Server database.
Per-Frame Routing
Priority
Choose whether to select per-frame routing priority. When enabled, the virtual channel ID
is used in conjunction with a frame header to form the final virtual channel ID.
Suppress Class F Traffic Applies only if VC-encoded address mode is also set. When selected, translative
addressing (which allows private devices to communicate with public devices) is disabled.
Insistent Domain ID
Mode
Set this mode to make the current domain ID insistent across reboots, power cycles, and
failovers. This mode is required fabric wide to transmit FICON
data.
