Maximum size (MB)
Specifies the maximum size for the trace file. Once the trace file reaches the maximum size, the trace will wrap, overwriting the oldest trace information.

The default is 1.
Maximum data (bytes)
Specifies the maximum data (in bytes) to trace for channel commands that transfer data. The valid range is from 0 to 32 KB. The actual amount of data that is traced, will be the lesser of the specified value and the amount of data that was actually transferred. The default is 8192.
ESCON link events
If the channel is ESCON, use this option to capture additional trace information that may be useful in rare instances.
