Filter pages
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.
4.8.1 Filter set
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.
You can check the MAC Filter and give a Name then add it. You also can check
the IP Filter and give an ID/Name then clicking on Add. Click OK to save the
configuration permanently or Reload to refresh the page. Please click OK before
editing.
Click on a filter set to select the set you want to edit or remove. Second, click
on Edit to enter the rule page, or click on Remove 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.
