Using Advanced Performance Monitoring
In the previous example, offset (A) is the byte offset value in the header of the FC
frame and value 0[, value 1, ..., value 3] (B) is a user-defined value, or a set of
user-defined values. At least one value must be specified (value 0), but you can
specify up to four values.
For a filter to be matched, all the elements specified in the filter must provide a
match.
For an element to produce a match, the value at offset (A) in the frame being
transmitted must match at least one of the user-defined values (B).
The range of offsets that can be matched using filters is 0 to 63. Examples of FC
Frame statistics that can be measured using filters are:

{offset, value 0[, value 1, ..., value 3]}
