Traffic/Security Filters
For example, suppose you wanted to configure these six filters on the switch:
Filter Type Filter Value Action Destination Ports
Source-Port Inbound ports: A1, A2* Drop D1-D4
Multicast 010000-123456 Drop C1-C24, D5-D10
Multicast 010000-224466 Drop B1-B4
Protocol Appletalk Drop C12-C18, D1
Protocol ARP Drop D17, D21-D24
*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:
Figure 9-15. Configuring Various Traffic/Security Filters
Displaying Traffic/Security Filters. This command displays a listing of all
filters by index number and also enables you to use the index number to
display the details of individual filters.
Syntax: show filter
Show a table listing the filters configured in the switch, with
corresponding filter index numbers.
[index]
Lists the filter type and other relevant data for the filter
corresponding to the index number. Also lists, for each
outbound destination port in the switch, the port num-
ber, port type, and filter action (forward or drop). The
switch assigns the lowest available index number to a
new filter. If you delete a filter, the index number for
that filter becomes available for the next new filter you
create.
