	amount of IP multicast packets are bridged. To enable IGMP pruning:

	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.
