ag 2 NOTES OPERANDS • Manage device WWN to N_Port group mappings. • Manage device WWN failover to N_Ports configured as preferred failover ports. • Enable or disable device WWN mappings. • Configure the reliability limit for the preferred N_Port. • Save the configured F_Ports, static F_Ports for the given N_Port, and F_Ports for which the given N_Port is a preferred one. • Delete the backup mappings for the given N_Port, if any. • Display the saved mappings for the given N_Port, if any. AG configuration changes are saved persistently as configuration keys. Use the portCfgNPort command to set a port as N_Port. This command supports multiple configurations for mapping device logins to N_Ports for the purposes of load balancing and redistribution in the event of a fabric change. If multiple mappings are configured, the system considers the available mappings in a fixed order of priority to determine which of the available N_Ports should be assigned to the login request. The first eligible mapping is chosen in the order specified below. 1. Device WWN to N_Port 2. Device WWN to N_Port Group 3. Automatic device WWN load balancing. 4. F_Port to N_Port 5. F_Port to N_Port Group The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. AG is supported only on selected Brocade hardware platforms. Refer to the Access Gateway Administrator's Guide for hardware support and AG configuration procedures. In non-AG mode, only two actions are available: --modeenable and --modeshow. The --backupmappingsave, --backupmappingdel and --backupmappingshow commands can be executed if the auto policy is disabled. This command has the following operands: --help Displays the command usage. --show Displays the current configuration of the Access Gateway. This includes all N_Ports and F_Ports that are currently online, failover and failback settings as well as any online F_Ports that are currently mapped to N_Ports. Failover and failback policies are displayed as enabled (1) or disabled (0). --modeshow Displays the current Access Gateway operating mode of the switch as either enabled or disabled. --modeenable Enables Access Gateway mode on a switch. Long distance mode settings should be cleared for all ports on the NPIV edge switch to which the AG is connected. Otherwise, the NPIV switch port displays the long distance port type along with the F_Port. Fabric OS Command Reference 25 53-1002746-01
