3 Changing system configuration parameters 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. Enabling insistent domain ID mode 1. Open the Switch Administration window as described on page 29. 2. Disable the switch as described in "Enabling and disabling a switch" on page 34. 3. Click the Configure tab. 4. Click the Fabric subtab. 5. Select the Insistent Domain ID Mode check box. 6. Click Apply. 7. Enable the switch as described in "Enabling and disabling a switch" on page 34. 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. 3. Click the Configure tab. 4. Click the Virtual Channel subtab. 5. Type a value in the VC Priority field you want to change. Valid values for all fields are 2 or 3. 6. Click Apply. 7. Enable the switch as described on page 34. 38 Web Tools Administrator's Guide 53-1000606-01
