int = int digit | digit
hex = 0x hex digit | hex hex digit
digit = 0|1|2|3|4|5|6|7|8|9

Description
All kernel diagnostics have at least one item list parameter to specify which ports to test. The normal
default value for this parameter is to select everything.
NOTE: This is not a command; rather, it is a common parameter to many commands.
If you want to restrict the items to be tested to a smaller set, the parameter value is an item list with the
following characteristics:
• It is a comma-separated list of items.
• Each item in the list might be a single element or a range of elements indicated by a hyphen (-) and be
mixed with individual values.
• Spaces and tab stops are skipped.
• Each item might be preceded by an optional slot number and foward slash (/).
For example, 0,3,4-6,1; 0,1,3,4,5,6; and 0 3 4-6 1 each select items 0, 1, 3, 4, 5,
6
Besides the syntax rules, there are also some grammatical restrictions on the slot numbers:
• Once specified, a slot selection applies to all items to the right of the slot selections until the next slot
selection or the end of the item list. For example, 1/0 - 15 and 1/0 - 1/15 are equivalent.
• If no slot number is specified, user port lists are specified by area number. For instance, 0, 16, 32
and 1/0, 2/0, 3/0 specify the same ports on a 16-port/blade system. On that same system, 1/0,
16, 32 is not a valid list: even though it’s syntax is legal, the ports do not exist.
• If no slot number is specified, all lists except user port lists will use the default slot 0.
• No list type except for user port lists might specify multiple conflicting slot numbers. For instance, 1/0,
2/0, 3/0 is a valid user port list but is not valid for any other type of list.
