dlsSet 2 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. Operands --enable -lossless Enables the Lossless feature. Frame loss is reduced while the path is rerouted. If DLS is set on the switch, this command adds the Lossless feature to the existing DLS legacy mode. If DLS is not set on the switch, this command enables both DLS and the Lossless feature. The Lossless feature is by default disabled. --disable -lossless Disables the previously enabled Lossless feature. Execution of this command is equivalent to the legacy dlsSet command. Dynamic load balancing is enforced but not without frame loss. DLS (legacy mode) continues to be enabled after Lossless is disabled. Use dlsReset to disable DLS completely. --help Displays the command usage.
