Turn on the in-order delivery option.

Synopsis

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 ensures that frames

are not delivered out-of-order, even during fabric topology changes.

The default behavior is for the in-order delivery option to be off.

This command must be used with care, because it can cause a delay in the

establishment 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.

Operands None.
