portLedTest portLedTest Cycles user port LEDs. Synopsis portledtest [--slot slot_number] [-ports itemlist] [-uports itemlist] [-npass count] [-action value] Description Use this command to exercise the user port LEDs in the current switch. When used without a port specifier, all user ports are tested. For each port, the command cycles through the ON and OFF state by setting the ATTN LEDs to green for the ON condition and unlighted for the OFF condition. The SPEED LEDs are initially set to black before the test starts. The SPEED LEDs turn green while the test is running. This diagnostic cannot be run on an operational switch. You must disable the switch using the chassisDisable command before you can run this test. After the command completes, the ATTN LEDs flash amber, indicating that the command has finished and exited. Enable the switch using the chassisEnable command to set the ATTN LEDs back to black. The port LED behavior varies depending on the platform. Notes You cannot interrupt the test by pressing the return key (). 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 This command has the following operands: --slot slot Specifies the slot number on bladed systems. When used without the port option, this option exercises all user ports in the specified slot. When used with the port option, only the ports specified for the specified slot are tested. -ports itemlist Specifies a list of front-end blade ports to test. When a specific port is specified, the blade port reference is used. If you want to test a specific user port, you will need root access to the bladePortMap command to map the specified blade port to the desired user port. You can also use the -uports option to specify the user ports. Refer to itemList for more information on the itemlist parameter. When specifying ports on a chassis, the -ports operand must be preceded by the --slot operand. -uports itemlist Specifies a list of user ports to test. If this operand is omitted, by default the test will run on all valid blade ports in the slot. Refer to itemList for more information on the itemlist parameter. This option is only available for 16 Gbps-capable blades. -npass count Specify the number of times to perform this test. The default value is 10. Brocade Fabric OS Command Reference 785 53-1004112-02
