dlsReset

Disables Dynamic Load Sharing (DLS).

Synopsis dlsreset

Description Use this command to disable Dynamic Load Sharing.

If DLS is turned off, 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. Refer to the dlsSet help page for a full

description of load sharing options, including the Lossless feature and the E_Port Balance Priority feature.

The behavior of this command depends on the routing policies configured on the switch:

• If a port-based routing policy is in place, DLS is disabled by default, and dlsReset returns the DLS setting to

default. This command resets the Lossless, and the E_Port Balance Priority features along with the DLS

feature and returns a message stating that "DLS is not set".

• If an exchange-based routing policy is in place, DLS is always enabled. It cannot be disabled and the dlsReset

command fails. The command generates a message stating that "DLS is enabled and cannot be changed with

the current routing policy". If Lossless is enabled, the feature remains enabled until you disable it with the

dlsSet --disable -lossless command. If E_Port Balance Priority is enabled, the feature remains enabled until

you disable it with the dlsset --disable -eportbal command.

• If DLS is already disabled, the command output confirms the disabled status: "DLS is not set (unchanged)."

• If two-hop lossless DLS is enabled while DLS is disabled, the command output shows the message:

"Two-hop lossless requires LosslessDLS be enabled prior to enabling."

Refer to aptPolicy for information on routing policies.

Notes The Lossless feature is not supported on GbE ports and FCoE ports. On unsupported platforms, this command

exits with an appropriate message.

On platforms that do not support the E_Port Balance Priority feature, the command output indicates that the

feature is not supported.

The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric

OS Commands" and "Command Availability" for details.

Operands None
