Filters
This filter is configured as follows:
Filter identifier – port number of the port attached to LAN 4 as
a destination
Filter fields – protocol type = AppleTalk I, match source LAN =
LAN 1, match destination address = 01-00-00-00-00-00 with
mask 01-00-00-00-00-00, match
This filter will block AppleTalk multicasts (or all AppleTalk traffic
if the destination address field is omitted) from LAN 1 to LANs 2
and 3, yet AppleTalk I traffic to LAN 4 will be permitted (because
LAN 4 is not specified for filtering).
