GigaX Series L3 Managed Switch User Guide

4.8Filters

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.

4.8.1Filter 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 38).

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 40, 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.
