Application of the FC Service Test

This topic describes the implementation and application scenarios of the FC service test.

Function Implementation

The procedure of performing the FC service test on the 12LOM board is as follows: enable the testing mode on the 12LOM board, simulate one or two node ports (N-Ports), initialize the FC link, log in to the device under test (DUT), start and stop sending and receiving the data packets.

The DUT is a device to be tested, which can be any board that can process the FC service. Currently, the following boards in the transport network can function as the DUTs.

As the FC service board for transparent transmission
- OptiX OSN 6800/3800/OptiX OSN 8800 series: LWX, LQM, LOM, TQM, TOM
As the FC service board for distance extension
- OptiX OSN 6800/3800/OptiX OSN 8800 series: LOM

As the FC testing device, the 12LOM board can support three application scenarios to meet the different testing requirements.

Single-Port Test

As shown in Figure 1 and Figure 2, the data packets are sent and received at the same port (port 3 or port 7) on the 12LOM board. In this case, you can perform the sing-port test after setting the port under test to the FC service test mode. The test is applicable to the networking that comprises a single or multiple DUTs. The test is only applicable to the transparently-transmitted FC service.

Dual-Port Test

As shown in Figure 3, the data packets are sent and received separately at two different ports on the 12LOM board. In this case, you need to set the two boards to the FC service test mode before perform the dual-port test. The test is applicable to the transparently-transmitted FC service and the FC service that is processed through the FC-BB protocol.

The FC-BB protocol test is a test on the FC service that is processed through the FC-BB protocol, which enables long-distance transmission of the FC service.

There are two test lines for the dual-port test.

One test line goes from the sending end port 3 to the receiving end port 7, which tests the line status anticlockwise.
Another test line goes from the sending end port 7 to the receiving end port 3, which tests the line status clockwise.

NOTE:

In the case of dual-port working mode, only the interconnection test on two ports on the same 12LOM board is supported currently. That is, port 3 can interconnect with port 7 on the same 12LOM board for the test.

Interconnection Test with the Switch

As shown in Figure 4, Figure 5, and Figure 6, when the 12LOM board is set to the FC service test mode, it can interconnect with the FC switch for the interconnect test. The test is applicable to the transparently-transmitted FC service and the FC service that is processed through the FC-BB protocol.
