--pciloopback Checks the communications path between the host and the IO Controller
(IOC).
port_id Specifies the ID of the port for which you want to send a health check
message.
-p pattern Displays the data pattern.
-c frame_count Specifies the frame count.
--loopback Tests the data path from the IOC to the desired network loopback point
(internal, serdes, external) and back. This is an offline diagnostic test.
port_id Specifies the ID of the port on which you want to run a loopback test.
-t loopback_type Specifies the loopback test type. Possible values include the following test
types:
• int - Internal loopback, the default
• serdes - SerDes loopback
• ext - External loopback).
If the loopback type is not specified, all loopback tests run.
-s speed Specifies the link speed as 8, 4, 2, or 1 Gbps. This is an optional parameter. If
not specified, then 8, 4, and 2 Gbps speeds are tested on the 8 Gbps adapter
and 4, 2, and 1 Gbps speeds are tested on the 4 Gbps adapter.
-c frame count Specifies the frame count.
-p pattern Specifies the pattern (must be one hex word).
--memtest Performs a generic memory test using different algorithms.
port_id Specifies the ID of the port on which you want to run a memory test.
--queuetest Sends a health check message from the host to the firmware through
message queues memory mapped over the PCI.
port_id Specifies the ID of the port on which you want to run a queuetest.
-q queue_num Specifies the CPE/RME queue number from 0 to 3. If the queue number is
not specified, all queues are tested.
