Editing a source-port filter

The switch includes in one filter the action(s) for all destination ports and/or trunks configured for a given source port or trunk. Thus, if a source-port filter already exists and you want to change the currently configured action for some destination ports or trunks, use the filter source-port command to update the existing filter. For example, suppose you configure a filter to drop traffic received on port 8 and destined for ports 1 and 2. The resulting filter is shown on the left in Assigning additional destination ports to an existing filter. Later, you update the filter to drop traffic received on port 8 and destined for ports 3 through 5. Since only one filter exists for a given source port, the filter on traffic from port 8 appears as shown on the right in Assigning additional destination ports to an existing filter:
