Brocade Communications Systems 804 manual Pciloopback, Loopback, Memtest, Queuetest

B diag

--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.
-sspeed	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.
-cframe count	Specifies the frame count.
-ppattern	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.

Example To display detailed information about a specific port:

#bcu diag --tempshow temperature: 44.348787 C

#bcu diag --beacon 1/1 on Port beacon turned on

#bcu diag --beacon 1/1 on

Link end-to-end beacon turned on
