Figure 12-15. Configuring Various Traffic/Security Filters
For example, suppose you wanted to configure the filters in table 12-3 on a
switch. (For more on source-port filters, refer to "Configuring a Source-Port
Traffic Filter" on page 12-17.)
Table 12-3. Filter Example
Filter Type Filter Value
Source-Port Inbound ports: A1, A2* Drop
Multicast 010000-123456
Multicast 010000-224466
Protocol Appletalk
Protocol ARP
*Because the switch allows one inbound port in a source-port filter, the
requirement to filter ports A1 and A2 means you will configure two
separate source-port filters.
The following commands configure the filters listed above:

Filter Indexing

The switch automatically assigns each new filter to the lowest-available index
(IDX) number. The index numbers are included in the show filter command
described in the next section and are used with the show filter < index >
command to display detailed information about a specific filter.
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.
