Note: Enter commands in lowercase only; mixed case is for readability. iodSet 2 iodSet Enables the in-order delivery (IOD) option. Synopsis iodset Description Use this command to enforce in-order delivery of frames during a fabric topology change. In a stable fabric, frames are always delivered in order, even when the traffic between switches is shared among multiple paths. However, when topology changes occur in the fabric (for instance, a link goes down), traffic is rerouted around the failure and some frames might be delivered out of order. This command ensures that frames are not delivered out-of-order, even during fabric topology changes. The default behavior is for the IOD option to be off. This command should be used with care, because it can cause a delay in the establishment of a new path when a topology change occurs. Only if there are devices connected to the fabric that do not tolerate occasional out-of-order delivery of frames, should this command be used. Note The execution of this command is subject to Admin Domain restrictions that may be in place. Operands Examples none To turn on the IOD option: switch:admin> iodset switch:admin> iodshow IOD is set See Also iodReset, iodShow Fabric OS Command Reference Manual Publication Number: 53-1000240-01 2-293
