Note: The MAC filter table contains 3 hidden rules. These rules are entered automatically by the system to ensure the user does not "lock" them out of the system. The first rule allows any and all ARP frames through the system. The second rule allows all IPv4 frames with the destination MAC address of the bridge to go through. The third rule allows all IPv4 frames with the source MAC address of the bridge to go through.
Note: On a windows based machine, to find a MAC address, at a dos prompt type ipconfig /all.
The apply button will temporarily save this connection. To make the change permanent you need to click on Save Settings (at the side of the page). At the system commands page, click on Save All.
4.6.7 Multicast
Multicasting is a form of limited broadcast. UDP is used to send datagrams to all hosts that belong to what is called a "host group." A host group is a set of zero or more hosts identified by the same destination IP address. The following statements apply to host groups.
a.Anyone can join or leave a host group at will.
b.There are no restrictions on a host's location.
c.There are no restrictions on the number of members that may belong to a host group.
d.A host may belong to multiple host groups.
e.
Multicasting is useful when data needs to be sent to more than one other device. For instance, if one device is responsible for acquiring data that many other devices need, then multicasting is a natural fit. Note that using multicasting as opposed to sending the same data to individual devices uses less network bandwidth.
To enable Multicasting, click on Advanced and under Advanced, select Muliticast. Figure 16 illustrates a typical Multicast configuration.
