If the Diagnostics button is selected, the content pane appears as shown in
Figure 4-16.
Figure 4-16. Fibre Channel Port—Diagnostics
In the content pane, select the type of diagnostic test to perform: Loopback Test
or Read-Write Buffer Test. Then, under Test Configuration, specify the
following test parameters:
Data Pattern: Select the type of data pattern (jitter pattern) to use in the test.
Or, type the pattern to use into the boxes provided.
Data pattern sequences are the bit sequences that are transmitted by a
serializer onto a link or bit sequences received by a deserializer from a link.
The data pattern sets the test pattern for evaluating the jitter compliance of a
Fibre Channel link. Test bit sequences have a significant impact on
stressing the link’s jitter characteristics.
