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.
