3 System configuration parameters 5. Make the fabric parameter configuration changes. 6. Click Apply. 7. Enable the switch as described in "Enabling and disabling a switch" on page 47. Fabric settings Configure the following fabric settings on the Fabric subtab of the Configure tab: BB Credit The buffer-to-buffer credit is the number of buffers available to attached devices for frame receipt. The default BB Credit is 16. The range is 1-27. R_A_TOV Resource allocation timeout value (in milliseconds). This variable works with the E_D_TOV to determine switch actions when presented with an error condition. The default is 10000. The possible range is (2*E_D_TOV) -120000. Values must be multiples of 1000. E_D_TOV Error detect timeout value (in milliseconds). This timer is used to flag a potential error condition when an expected response is not received within the set time. The valid range is 1000 - (R_A_TOV/2) Datafield size The largest possible data field size (in bytes). The valid range is 256-2112. Sequence Level Switching Select this box to enable frames of the same sequence from a particular group to be transmitted together. When this option is not selected, frames are transmitted interleaved among multiple sequences. Under normal circumstances, sequence-level switching should be disabled for better performance. However, some host adapters have issues when receiving interleaved frames among multiple sequences. 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 Use the following procedure to enable insistent domain ID mode. 1. Open the Switch Administration window as described on page 41. 2. Disable the switch as described in "Enabling and disabling a switch" on page 47. 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 47. 50 Web Tools Administrator's Guide 53-1001343-01
