iodReset
The
iodReset
command turns off the in-order delivery option. This command allows
out-of-order delivery of frames during fabric topology changes.
This is the default behavior and allows fast rerouting after a fabric topology change.
iodSet
The
iodSet
command ensures that frames will not be delivered out-of-order, even
during fabric topology changes. In a stable fabric, frames are always delivered in order,
even when the traffic between switches is shared among multiple paths. However,
when some topology change occurs in the fabric, for instance, a link goes down, traf-
fic is rerouted around the failure. In general, there is no guarantee in this case that
some frame, queued behind a congested link, will not be delivered after a frame that
has been transmitted later, but is now taking the new path.
This command should be used with care, because it will cause a delay in the estab-
lishment of a new path when a topology change occurs. Use this command only if
there are devices connected to the fabric that do not tolerate occasional out-of-order
delivery of frames.
The default behavior is for the in-order delivery option to be off.
