Description
Use this command to enforce in-order delivery of frames during a
fabric topology change.
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 will be delivered out of order. This
command ensures that frames will not be delivered out of order, even
during fabric topology changes.

The default behavior is for the in-order delivery option to be off.
This command should be used with care, because it will 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.
