IP Filtering
Purpose IP filtering is available when you are routing between nets or VLANs.
It enables you to send data packets to specific workstations or user
groups across the VLANs. You define the members in these user
groups and the type of IP filtering. IP filtering uses either IP addresses
or specified IP protocols. It is specific for the individual switches, and
therefore, right-click the switch to access the IP filtering functions.
Before you start Look at the architecture of your network before starting. Make a list
of proposed user groups and their filter parameters. Then look at the
individual members to be included in the groups. This prevents work-
stations or subnets from being excluded when IP filtering is enabled.
Enabling IP Filtering IP Filtering is enabled by default. There are two default user groups,
which allow all traffic to pass. Enable is a toggle function, which also
allows you to disable IP Filtering:
1 Select IP Filtering Setup.
2 Select Enabled.
3 Set up any User Groups and Members required.
4 Click OK.
