portTrunkArea 2 Notes Operands deskew The time difference for traffic to travel over each F_Port trunk as compared to the F_Port trunk with the shortest travel time in the group. The value is expressed in nanoseconds divided by 10. The firmware automatically sets the minimum deskew value of the shortest F_Port trunk travel time to 15. Master Identifies the master port of the trunk group. Execution of this command is subject to the following restrictions: 1. Only F_Port trunk ports are allowed to be part of a TA. E/F/L/EX_Port will be persistently disabled. Private L_Ports remain online but will not run traffic. 2. Only one trunk master per TA is permitted. The second trunk master is persistently disabled. 3. The entire TA trunk group shares the same port WWN. 4. The port must be disabled before a TA can be assigned to a port or removed from a trunk group. 5. There is one port whose Default Area is the same as its Trunk Area. You cannot remove that port from the trunk group unless The TA is removed from all ports in the trunk group. 6. You must enable trunking on all ports to be included in a TA before you can create a TA. Use portCfgTrunkPort or switchCfgTrunk to enable Trunking on a port or on all ports of a switch. 7. N_Port ID Virtualization (NPIV) support is provided for up to 255 devices per TA. Note that this decreases the number of devices available per port, since all participating ports share the same area. 8. F_Port trunking is only supported in CORE PID formats. 9. Certain port configuration features are not supported within a TA and the command fails if one of these features is enabled on a port within the trunk group. These features include FastWrite, Port Swapping, Port Mirroring, Long Distance, Inter-chassis links (ICL), and FICON. 10. Ports from different Admin Domains are not allowed to join the same Trunk Area group. 11. On the Brocade FC4-48C, F_Port masterless trunk ports are not supported on ports 16 - 47. 12. Ports included in a TA share the same port index. The original port index may be removed in the process. This means that D, I zones referring to these indices are no longer part of the switch. For details and workarounds, refer to the Fabric OS Administrator's Guide. 13. Device Connection Control (DCC) Policy must be removed from ports prior to creating a TA. You can re-enable DCC policy after creating the TA. 14. You cannot assign a TA while AG mode is enabled. This command is supported only on Brocade 48000 and Brocade DCX enterprise-class platforms running Fabric OS v6.1 or later. For Firmware compatibility and upgrade/downgrade considerations, refer to the Fabric OS Administrator's Guide. 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. Masterless F_Port trunking requires an ISL Trunking license. This command supports the following operands: slot On enterprise-class platforms, specifies the slot number, followed by a slash (/). Fabric OS Command Reference 751 53-1001337-01
