This section provides the following information about how to manage
filters:

Displaying the managed filter list

Adding filters to the managed filter list
Deleting filters from the managed filter list
Verifying filter file syntax
Displaying the contents of a filter
When managing filters, if you edit an existing filter and do not first
remove it from every interface or user profile for which it is configured
and then reapply the new filter, the previously unedited version will still
apply. See Removing a Filter... sections on the next page.
To display the list of managed filters, use the following command:
list filters
The resulting display might look like the following example:
FILTERS
Filter Name Status
xfilter.in NORMAL
xfilter.out VERIFY FAILED
ljc_filter.fi NORMAL
l
The add filter command verifies filter syntax before adding a filter to
the managed list. If syntax is valid, no message is generated and the
command prompt returns. If syntax errors exist, messages are sent
describing them.
If the syntax is invalid, the filter is still added to the managed list with a
status of verify failed. To correct filter file errors, you must make
the changes to the original filter file using a text editor and re-TFTP the
file to FLASH memory. You must then use the verify filter
command to check the filter file syntax. For more information about
verify filter, see "Verifying Filter File Syntax" on page 232.
