Filter Commands LSB4 Reference Manual
6-4
Set/Define Filter
Parameters Filter
Specifies a particular filter list.
filtr
A value between 1 and 4.
Filter list numbers are associated with a particular port num-
ber using the Set/Define Switch command.
Append/Insert position
Identifies a location in the specified filter list for a particular
filter definition. To view a currently active filter list, enter a
Show or List Filter command. (For more information on these
commands, see Show/List Filter on page 6-11.)
Append
will place the new filter definition at the end of the
list.
Insert position defines a location of the new filter definition.
The filter will be placed in the list just prior to the value you
specify for the position; for example, if you enter a value of 3,
the new filter will be inserted into the list just before the filter
currently occupying position 3. If you enter a value larger
than the current number of filters on the list, the new filter will
be added at the end of the list.
All
Specifies that every data packet will be allowed or denied pas-
sage through the LSB4. Using the All parameter and specify-
ing Allow or Deny will affect all data packets regardless of
any filter specifications that follow.
Usually, the All keyword is placed at the end of a filter list to
prevent passage of all data packets not specifically identified
by the previous filters in the list.
Broadcast
Permits or denies passage of broadcast messages through the
LSB4.
