Configuring NetFlow
To enable NetFlow for ingress-bridged IP traffic in VLANs, perform this task:
Command
Router(config)# ip flow ingress layer2-switched
vlan vlan_ID[-vlan_ID] [, vlan_ID[-vlan_ID]]
Router(config)# no ip flow ingress layer2-switched
vlan vlan_ID[-vlan_ID] [, vlan_ID[-vlan_ID]]
This example shows how to enable NetFlow for ingress-bridged IP traffic in VLAN 200:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# ip flow ingress layer2-switched vlan 200
Enabling NetFlow for Multicast IP Traffic
To enable NetFlow for multicast IP, perform this task:
:
Command
Step 1
Router(config)# interface {vlan vlan_ID} |
{type slot/port} | {port-channel
port_channel_number}
Step 2
Router(config-if)# ip flow ingress
Step 3
Router(config-if)# ip multicast netflow {ingress
| egress}
For additional information about NetFlow for multicast IP, refer to the NetFlow Multicast Support
documentation, available at the following document:
Cisco IOS NetFlow Configuration Guide.
The NetFlow Multicast Support document contains a prerequisite specifying that you need to configure
multicast fast switching or multicast distributed fast switching (MDFS). However, this prerequisite does
not apply when configuring NetFlow multicast support on the Supervisor Engine 32 PISA.

Purpose
Enables NetFlow for ingress-bridged IP traffic in the
specified VLANs.
Note NetFlow for ingress-bridged IP traffic in a VLAN
requires that NetFlow on the PFC3B be enabled with
the mls netflow command.
Disables NetFlow for ingress-bridged IP traffic in the
specified VLANs.
End with CNTL/Z.
Purpose
Selects a Layer 3 interface to configure.
Enables NetFlow on the interface.
Enables NetFlow multicast traffic on the specified
interface (for PISA and PFC3B).
Specify ingress to enable NetFlow multicast ingress
