FC Service Test

In this user interface, you can set the working mode of the port, query and set the parameters of the FC service test.

Navigation Path

In the NE Explorer, select a board and choose Configuration > FC Service Test from the Function Tree. Click the Setting tab or Testing tab.

Buttons

Button	Description
Apply	Applies the current settings on the FC service test to the board.
Link	Sends a signal for connecting to the DUT and prepares to log in to the DUT. If connecting to the DUT is not performed, the indicator next to the button is in yellow. If connecting to the DUT succeeds, the indicator next to the button is in green. If connecting to the DUT fails, the indicator next to the button is in red.
Link Reset	Resets the connection status. This function is applied in the case of repeated connection failures or login failures.
Login	Sends a signal for logging in to the DUT and prepares to send and receive the data packets. If logging in to the DUT is not performed, the indicator next to the button is in yellow. If logging in to the DUT succeeds, the indicator next to the button is in green. If logging in to the DUT fails, the indicator next to the button is in red.
Start	Starts the FC service test. The FC test board and the DUT start sending and receiving the data packets.
Stop	Stops the FC service test. The FC test board and the DUT stop sending and receiving the data packets.
Clear	Clears the records on sending and receiving the data packets.

Parameters

**Table 1** Setting
Field	Value	Description
PORT3	Testing Mode, Service Mode	Sets the working mode of the port3.
PORT7	Testing Mode, Service Mode	Sets the working mode of the port7.

**Table 2** Testing
Field	Value	Description
WWN Address	For example: 10 00 00 01 88 88 88 01	The WWN address is similar to the IP address, which is represented by a hexadecimal character string. For the same FC service test, the WWN address must be unique in the network. Otherwise, the test is affected.
Speed	FC100, FC200, FC400	Indicates the speed of connecting to the FC service.
Rx Credit	1-20	The buffer-to-buffer flow control mode is adopted to control the traffic between a test board and the DUT. For every test frame that is sent by a test board, if there is no reply signal from the DUT, the value of Rx Credit decreases by 1. In this manner, when the value of Rx Credit reaches 0, the test board stops sending the test frame. Later, if there is a reply signal from the DUT, the value of Rx Credit increases by 1. Then the test board starts sending the test frame again.
Topology	P2P, Fabric	The P2P represents the transmission protocol used for a networking without the switch. If the P2P protocol is set, the Login button grays out. That is, the test board has logged in to the DUT by default. The Fabric represents the transmission protocol used for a networking with the switches.
Mode	Continue, Single Burse	Indicates the sending mode of a test frame. If the Single Burse mode is set, a test board stops sending the data packets after a fix number of data packets are sent. If the Continue mode is set, the test board sends the data packets continuously and only stops sending the data packets when you click the Stop button.
Payload Type	All Zero, All One, Increase, Decrease	Indicates the character type of a test frame.
Count	1-65535	Indicates the number of test frames that are sent. When Mode is set to Continue, this parameter is unavailable.
Utilization	1%-100%	Indicates the percentage of the sending speed of a test frame. During the FC service test, invalid characters are used to fill the gap between the test frames, namely, the frame gap. When Utilization is set to 100%, the frame gap of the system is 6 characters by default. The equation for calculating the frame gap: Number of the frame gaps = 6/Utilization
Frame Length (With SOF/EOF/CRC)	36-2148	Indicates the length of a test frame.
CRC Error Injection		Specifies whether to insert the CRC code. The CRC code is inserted in an abnormal test, but not in a normal test.
Tx Class3 Frames		Indicates the number of class 3 service frames sent by a test board.
Rx Class3 Frames		Indicates the number of class 3 service frames received by a test board.
Tx CRC Errors		Indicates the number of CRC error frames sent by a test board.
Rx CRC Errors		Indicates the number of CRC error frames received by a test board.
Rx OtherClass Frames		Indicates the number of non-class 3 service frames received by a test board.
Rx OverFrames		Indicates the number of overlength frames received by a test board.
Tx Credits		Indicates the consumed counts of the current receiving end.
Rx Utilization		Indicates the percentage of the receiving speed of a test board.
RTT Delay (us)		Indicates the inherent delay of a test board.
Link Fails		When testing the FC service is normal, if the interval between removing and plugging a fiber exceeds 100 ms, the system records a link failure.
