Turn on In Order Delivery (IOD) option.
Synopsis
iodSet
Availability

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. When topology changes occur, generally,
some frames are delivered out of order. This command insures 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.
Operands
None.
