Configuring NetFlow for Multicast IP Traffic
To configure NetFlow for multicast IP traffic, perform this task:
| Command | Purpose |
Step 1 | Router(config)# ip multicast netflow output-counters | (Optional) Enables the calculation of output bytes/packets for an ingress flow. |
Step 2 | Router(config)# ip multicast netflow rpf-failure | (Optional) Enables NetFlow for multicast data that fails the RPF check. |
Step 3 | Router(config)# interface{vlan vlan_ID} | {type slot/port} | {port-channel port_channel_number} | Selects a Layer 3 interface to configure. |
Step 4 | Router(config-if)# ip flow{ingress | egress} | Enables NetFlow multicast traffic on the specified interface (for RP and PFC). •  Specify ingress to enable NetFlow multicast ingress accounting. •  Specify egress to enable NetFlow multicast egress accounting. |
Here is another helpful blog on setting up NetFlow for multicast from the makers of Scrutinizer NetFlow Analyzer.
