3. Enter the crossporttest -lb_mode 5 command where 5 is the operand that causes the test to be run
on the internal switch components (this is a partial list—refer to the Fabric OS Command
Reference Manual for additional command information):
[-nframes count] Specify the number of frames to send.
[-lb_mode mode] Select the loopback point for the test.
[-spd_mode mode Select the speed mode for the test.
[-ports itemlist] Specify a list of user ports to test.
To test components to and from the HBA
1. Connect to the switch and log in as admin.
2. Enter the fPortTest command (refer to the Fabric OS Command Reference Manual for information
on the command options). This command is not supported on the SilkWorm 3016 internal ports 1
through 14.
Example
This example executed the fPortTest command 100 times on port 8 with payload pattern 0xaa55,
pattern width 2 (meaning word width) and a default payload size of 512 bytes.
Refer to Table 10-5 for a list of additional tests that can be used to determine the switch components that
are not functioning properly. Refer to the Fabric OS Command Reference Manual for additional
command information.
