Figure 5-38 SNMP Configuration Interface
Configuring Multicast
Multicast is a transmission mode for data packets. When there are multiple hosts to receive the
same data packets, multiple cast is the best option for reducing the bandwidth and the CPU
load. The source host can send out just one data for transit. This function also depends on the
relationship of the group member and the router group.
