fportTest Functional test of F->N, N->F point-to-point path. Synopsis fporttest [-nframes count][-ports itemlist][-seed payload_pattern][-width pattern_width][-size pattern_size] Availability admin Description Use this command to verify the functional operation of the switch by sending ELS ECHO frames from the switch F_Port transmitter and receiving ELS ECHO ACC from the N_Port device into the F_Port receiver. This exercises all the switch components, from the main board, to the SFP, to the fiber cable, to the SFPs (of the N_Port devices and the switch F_Port), and back to the main board. The cables and SFPs connected should be of the same technology; that is, a short wavelength SFP (switch) port is connected to another short wavelength SFP (device) port using a short wavelength cable, a long wavelength port is connected to a long wavelength port; and a copper port is connected to a copper port. Only one frame is transmitted and received at any one time. The port LEDs rapidly flicker green while the test is running. The test method is as follows: 1. Determine which ports are F_Ports. 2. Create an ELS_ECHO frame with payload size, data pattern build in or payload size, data pattern. 3. Transmit frame F through the F_Port, with D_ID, to the N_Port device. 4. Wait for the N_Port device to respond ECHO ACC. 5. Compare ECHO data transmitted to ECHO data received. 6. Repeat steps 3 through 5 for all ports present until either the number of frames requested is reached, or all ports are marked bad. You can specify a payload pattern to be used when executing this test. If the pattern is not user specified, then at every 30 pass, a different data type from a palette of seven is used to generate a different data pattern to create the frame. The data pattern is generated based on data type. Some data types might generate a different data pattern on every pass; other data types might not change the data pattern in every pass. These seven data types are repeated every 210 pass. The data palette is as follows: CSPAT(0): BYTE_LFSR(1): CHALF_SQ(2): QUAD_NOT(3): CQTR_SQ(4): CRPAT(5): RANDOM(6): 0x7e, 0x7e, 0x7e, 0x7e, ... 0x69, 0x01, 0x02, 0x05, ... 0x4a, 0x4a, 0x4a, 0x4a, ... 0x00, 0xff, 0x00, 0xff, ... 0x78, 0x78, 0x78, 0x78, ... 0xbc, 0xbc, 0x23, 0x47, ... 0x25, 0x7f, 0x6e, 0x9a, ...
