NetFlow Analyzer is based on automatic discovery and so the NetFlow exporting devices are automatically discovered and reports are generated within seconds of receiving the flows. Once the configuration is done and saved, flows will be exported to the server where NetFlow Analyzer is installed.

IP Multicasting can be viewed using the Flexible NetFlow, including the multicasting fields in exports. (config) ip multicast netflow rpf-failure (config) ip multicast netflow output-counters NetFlow Analyzer displays IP Multicasting reports based on volume, speed, utilization and packets.Įnabling Multicast routing in Cisco routersįollow the commands below to be enable Multicast on Cisco routers: However, only the members of a group receive the message. Any host, regardless of whether it is a member of a group, can send to a group. A group of hosts consists of both senders and receivers. In a multicast environment, packets delivered to group members are identified by a single multicast group address. However, the IP Scan tool would be a better choice for the Layer 3 discovery.

This is useful for discovering all the devices that are present. MikroTik’s ping tool will allow you to ping both Layer 2 and Layer 3 broadcast and multicast addresses. IP Multicasting allows a host to send packets to a specific group of hosts. Pinging Broadcast and Multicast addresses. This option needs addition configuration in the device to export the multicast traffic information. NetFlow Analyzer shows the Multicast traffic information that passes through the interface.
