To change the named source-port filter used on a port or port trunk,
the current filter must first be removed, using the no filter source-port
named-filter <filter-name > command.
A named source-port filter can only be deleted when it is not applied
to any ports.

Defining and Configuring Named Source-Port Filters

The named source-port filter command operates from the global configuration
level.
[no] filter source-port named-filter <filter-name>
Syntax:
Defines or deletes a named source-port filter. The <filter­
name> may contain a maximum of 20 alpha-numeric
characters (longer names may be specified, but they are not
displayed.) A filter-name cannot be a valid port or port trunk
name.
The maximum number of named source-port filters that can
be used is equal to the number of ports on a switch.
A named source-port filter can only be removed if it is not in
use (use the show filter source-port command to check the
status). Named source-port filters are not automatically
deleted when they are no longer used.
Use the no option to delete an unused named source-port filter.
filter source-port named-filter <filter-name > drop < destination-port-list >
Syntax:
Configures the named source-port filter to drop traffic having
a destination on the ports and/or port trunks in the <
destination-port-list >. Can be followed by the forward option
if you have other destination ports or port trunks previously
set to drop that you want to change to forward. For example:
filter source-port named-filter <filter-name > drop < destina­
tion-port-list > forward < destination-port-list>
The destination-port-list may contain ports, port trunks, and
ranges (for example 3-7 or trk4-trk9) separated by commas.
