Configuring dynamic load sharing 14 Configuring dynamic load sharing The exchange-based routing policy depends on the Fabric OS dynamic load sharing feature (DLS) for dynamic routing path selection. When this policy is in force, DLS is always enabled and cannot be disabled. When the port-based policy is in force, you can enable DLS to optimize routing. When DLS is enabled, it shares traffic among multiple equivalent paths between switches. DLS recomputes load sharing either when a switch boots up or each time an E_Port or FX_Port goes online or offline. Enabling this feature allows a path to be discovered automatically by the FSPF path-selection protocol. For more information regarding DLS, refer to the dlsset command in the Fabric OS Command Reference. To configure dynamic load sharing, perform the following steps. 1. Open the Switch Administration window as described in "Opening the Switch Administration window" on page 31. 2. Select the Routing tab. 3. Select On in the Dynamic Load Sharing (DLS) area to enable dynamic load sharing or select Off to disable dynamic load sharing. When the exchange-based routing policy is in effect, the DLS radio buttons display on the Routing tab 4. Click Apply. The warning message, "Credit Recovery for Long distance links should be turned off using CLI while enabling DLS" displays. 5. Click OK.
