2 dlsSet dlsSet Enables the dynamic load sharing (DLS) option. Synopsis dlsset Description Use this command to turn on DLS when a fabric change occurs. Routing is generally based on the incoming port and the destination domain. This means that all the traffic coming in from a port (either an E_Port or an Fx_Port) directed to the same remote domain is routed through the same output E_Port. To optimize fabric routing, when there are multiple equivalent paths to a remote domain, traffic is shared among all thse paths. Regardless of the setting of the DLS option, when ports come up, new routes are always added to optimize load sharing. Furthermore, when DLS is enabled, load sharing recomputed after the following events: A change in the fabric occurs; A local E_Port goes up or down; A local Fx_Port goes down. During load sharing recomputation, existing routes might be moved to maintain optimal balance. This can cause momentary frame loss along these routes. In contrast, if DLS is turned off (using dlsReset), load sharing calculations are used only to place new routes. Once placed, existing routes are never moved from one output E_Port to another unless the original output E_Port is no longer a recognized path to the remote domain. Optimal balance is rarely achieved with this setting. The DLS option is on by default. DLS is not supported in certain routing policies. Refer to aptPolicy for more information on routing policies. The execution of this command is subject to Admin Domain restrictions that may be in place.
