Filter Numbers

When you add a filter, the Model 5390 server assigns it a number that remains associated with it
until you delete the filter. The filter subcommand list displays this number, and you specify the
number when you delete, enable, or disable a filter (see Filter Lists on page A13-6 for permissible
ways to specify filters)

Filter Lists

The delete, enable, and disable subcommands accept a filter_list argument. A filter list can be a
filter number, a string of filter numbers separated by commas, or a range of filter numbers. Use a
dash (–) to separate the beginning and end of a range, or use it before or after a filter number. Used
before a filter number, a dash indicates all defined filters up to and including that number; used after
a filter number, a dash indicates all filters from that number up to and including the highest numbered
filter.
Specifying an asterisk (*), the word all, or a dash (–) by itself for a filter list indicates all filters.
Table A13-2 shows sample subcommands using filter lists.
When you delete filters, their numbers remain unused until you add another filter; the added filter
is then assigned the lowest unused number. If you invoke a subcommand with a range that includes
unused numbers, the subcommand operates on the assigned filters but displays an error message
for each unused number. This does not happen when you specify a group of filters by entering a
number with a leading or trailing dash; in this case, unused numbers are ignored.

Table A13-2. Sample Commands using the filter_list Arguments
Argument Description
delete 2 Deletes filter 2. A subsequent list subcommand will not
display an entry for filter number 2.
disable 3–6 Disables filters 3, 4, 5, and 6. If one of these numbers
represents a deleted filter or an existing filter associated
with an inactive interface, an error message is displayed for
that number; the other filters in the range are disabled.
