Configure Permanent Multicast Filtering
Multicast filtering allows you to block or forward traffic over each port for one multicast group.
To access the Static Multicast Filtering Table Configuration screen, select Configure Filtering and
Forwarding Table from the System Configuration menu. Then select Configure Permanent Multicast
Filtering from the bottom of the Configure Filtering and Forwarding table screen. The following screen
appears:
Figure 6-23. Static Multicast Filtering Table Configuration screen
To make a change to the Static Multicast Filtering Table, choose Add or Remove in the Action field. Then
enter the MAC Address and the member port numbers in the desired fields, for example Master and Slave
1 if there are two Switches in your stack. Press APPLY to put the changes into effect.
Configure IGMP
Internet Group Management Protocol (IGMP) allows multicasting on your network. When IP Multicast
Filtering is enabled, the Switch can intelligently forward (rather that broadcast) IGMP queries and reports
sent between devices connected to the Switch and an IGMP-enabled device hosting IGMP on your network.
Basically, in these submenus you define whether the Switch can intelligently forward IGMP packets, and you
must also define which 802.1Q VLANs (if present) can send and receive IGMP and Multicast packets.
