Filter Indexing; Editing A Source-Port Filter - ProCurve 2610 Manual

Traffic/Security Filters
Using Source-Port Filters

Filter Indexing

The switch automatically assigns each new source-port filter to the lowest-
available index (IDX) number. If there are no filters currently configured, and
you create three filters in succession, they will have index numbers 1 - 3.
However, if you then delete the filter using index number "2" and then
configure two new filters, the first new filter will receive the index number "2"
and the second new filter will receive the index number "4". This is because
the index number "2" was made vacant by the earlier deletion, and was
therefore the lowest index number available for the next new filter.

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. 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 figure 10-5. 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 figure 10-5:
