Diagnostics
Performing Ethernet loopback tests through BCU
Use the ethdiag --loopback command to run an Ethernet loopback test.
bcu ethdiag --loopback <port_id> [-t <loopback_type] [-c <frame_count>] [-p
pattern]
where:
port_id
-t loopback-type
-c frame count
-p pattern
NOTE
You must disable the port before running a loopback test. Use BCU port --disable <port_ID>
command.

PCI loopback test

Use BCU commands or HCM to perform a PCI loopback test for a specific port. In this test, a data
pattern is sent from the host to adapter firmware through the PCI bus. The returned data is
validated to determine PCI operation.
NOTE
You must disable the port before you run loopback tests.
Performing PCI loopback tests through BCU
Use the diag --pciloopback BCU command to perform a PCI loopback test.
diag --pciloopback <port_id> [-p <pattern>] [-c <frame_count>]
where:
port_id
pattern
frame count
Performing PCI loopback tests through HCM
Use the Hardware Tests tab on the Diagnostics dialog box to perform a PCI loopback test as follows.
1. Launch the HCM.
2. Select Configure > Diagnostics.

ID of the port for which you want to run the test. This could be the PWWN, port
hardware path, or user-specified port name. This could also be the
adapter-index/port-index. For example, to specify adapter 1, port 1 you would
use 1/1 as the port identification.
Specifies the loopback type. Possible values are serdes, and ext.
Specifies the frame count.
Specifies the pattern (must be one hex word).
ID of the port from which you want to run the test. This could be the PWWN,
port hardware path, or user-specified port name. This could also be the
adapter-index/port-index. For example, to specify adapter 1, port 1, you would
use 1/1 as the port identification.
Specifies the data test pattern. Must be at least one hexadecimal word.
Specifies the frame count as an integer from 0 to 4,294,967,295.
