You must connect the fabrics through the gateway device, and make sure that the configure parameters are compatible with the gateway device. You may be required to reconfigure the following parameters, depending on the gateway requirements: NOTE: Consult your gateway vendor for supported and qualified configurations. • R_A_TOV: Specify a Resource Allocation Timeout Value compatible with your gateway device. • E_D_TOV: Specify an Error Detect Timeout Value compatible with your gateway device. • Data field size: Specify the maximum Fibre Channel data field reported by the fabric. Verify the maximum data field size the network-bridge can handle. Some bridges may not be able to handle a maximum data field size of 2112. • BB credit: Specify the number of Buffer-to-Buffer credits for Nx_Port devices. • Suppress Class F Traffic: Use this parameter to disable class F traffic. Some network-bridge devices may not have a provision for handling class F frames. In this case, the transmission of class F frames must be suppressed throughout the entire Remote Switch fabric. To set the access and reconfigure these parameters: 1. Connect to the switch and log in as admin. 2. Enter the switchDisable command to disable the switch. 3. Enter the configure command. 4. At the Fabric Parameters prompt enter yes. 5. Press Enter to scroll through the Fabric Parameters without changing their values, until you reach the parameter you want to modify. 6. Specify a new parameter value that is compatible with your gateway device. 7. Press Enter to scroll through the remainder of the configuration parameters. Make sure that the configuration changes are committed to the switch. 8. Repeat for all switches in the fabrics to be connected through a gateway device. These parameters must be identical on each switch in the fabric, and between fabrics connected through the gateway device. 470 Using Remote Switch
