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.

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 by default disabled, and dlsReset returns the
DLS setting to default. If Lossless was enabled, this command removes the Lossless option
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
cannot be changed with current routing policy”. If Lossless is enabled, the feature remains
enabled until you disable it with the dlsSet --disable -lossless command.

•

If DLS is already disabled, the command output confirms the disabled status:“DLS is not set
(unchanged)”

Refer to aptPolicy for information on routing policies.

Notes

The Lossless feature is supported only on the Brocade DCX and DCX-4S chassis with 8G blades (FC
ports only), and on the Brocade 300, 5100, 5300 and 7800 switches. On the Brocade 7800 and
FX8-24, the Lossless feature is supported only on FC ports. On unsupported platforms, this
command exits with an appropriate message.

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
