Configure MAC Address Filtering
The Static Filtering Table contains filtering information configured into the Switch by (local or network) management
specifying destination addresses which are not allowed to be forwarded. The Switch will check both the destination and
source MAC addresses on all packets.
To access the Static Filtering Table, select Configure Filtering and Forwarding Table from the
Configuration menu. Then select Configure MAC Address Filtering from the bottom of the Configure
Filtering and Forwarding Table screen. The following screen appears:
Figure 6-22. Static Filtering Table screen
To make a change to the Static Filtering Table, choose Add or Remove in the Action field. Then enter the MAC
Address and VLAN (if Port-based or IEEE 802.1Q VLANs are enabled) and press APPLY.
Configure IGMP Filtering
Internet Group Management Protocol (IGMP) allows multicasting on your network. When IP Multicast Filtering is
Enabled , the Switch can intelligently forward (rather than broadcasting) IGMP queries and reports sent between devices
connected to the Switch and an IGMP-enabled device hosting IGMP on your network. When enabled for IGMP snooping, the
Switch can open or close a port to a specific Multicast group member based on IGMP messages sent from the device to the
IGMP host or vice versa.
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.
To access the IGMP Configuration screen, choose Configure IGMP Filtering from the Configuration menu.
