2.3.10 Multicast
The multicast interface is shown as in Figure 2-24.
Multicast is a transmission mode of data packet. When there is multiple-host to receive the same data
packet, multiple-cast is the best option to reduce the broad width and the CPU load. The source host
can just send out one data to transit. This function also depends on the relationship of the group
member and group of the outer.
Here you can set multicast address and port. You also need to go to Live interface to set the protocol as
Multicast.

2.3.11 IEEE802
IEEE802.1X works standing for local and metropolitan area networks and port based network access
control protocol. It supports manual operation of the client to choose means of authenticating by which
to control it to access to the Local Area Networks or not. It supports the ability to authenticate, to
calculate fee, to ensure security and to maintain requirements. See Figure 2-25.
