Filters
The switch can filter certain traffic types according to packet header
information from Layer 2 to Layer 4. Each filter set includes a couple of
rules. You have to attach the filter set to certain ports to make the filter
work.
4.7.1 Filter Set
You can create a filter set by giving a name, ID and a mode of rules. The
switch defines two modes of rules, one is MAC mode and the other is IP
mode. Only the same mode of rules can bundle together to form a filter set.
Each mode has different fields to configure. For example, you can use IP
mode rule to filter FTP packets.
When you click on the
Filter Set
, the Filter Set page appears (Figure 44).
First, create a filter set by typing a name and ID, then clicking on
.
Second, click on the
button to select the set you want to edit or remove.
Third, click on
to enter the rule page as Figure 45, or click on
to remove the filter set. You have to follow the rules to make a
valid filter set.
•
One set consists of a type of rules. The rules having the same fields
to filter packets belong to one type. For example, two rules filter
packets with two destination IP addresses, then they are the same
type. But a rule filtering source IP address does not belong to the
same type.
•
Four types of rules can apply to ports at the same time. If there are
more than four types, the system automatically disables the rules.
