Configuring NetFlow
For information on configuring NetFlow ToS-based router aggregation on the MSFC, refer to the
following documentation:
Cisco IOS netFlow Configuration Guide.
Note • When you configure NetFlow aggregation on the MSFC, it is configured automatically on the PFC
and DFCs (see the “Configuring NetFlow Aggregation on the PFC” section on page 50-9).
• The PFC and DFCs do not support NetFlow ToS-based router aggregation.
Enabling NetFlow for Ingress-Bridged IP Traffic
In PFC3B or PFC3BXL mode with Release 12.2(18)SXE and later releases, NetFlow supports
ingress-bridged IP traffic. PFC3A mode does not support NetFlow for bridged IP traffic.
Note • When you enable NetFlow for ingress-bridged IP traffic, the statistics are available to the Sampled
NetFlow feature (see the “NetFlow Sampling” section on page 51-7).
• To enable NetFlow for bridged IP traffic on a VLAN, you must create a corresponding VLAN
interface, assign it an IP address, and enter the no shutdown command to bring up the interface.
To enable NetFlow for ingress-bridged IP traffic in VLANs, perform this task:
This example shows how to enable NetFlow for ingress-bridged IP traffic in VLAN 200:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# ip flow ingress layer2-switched vlan 200
Command Purpose
Router(config)# ip flow ingress layer2-switched
vlan
vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
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 PFC be enabled with the
mls netflow command.
Router(config)# no ip flow ingress layer2-switched
vlan
vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
Disables NetFlow for ingress-bridged IP traffic in the
specified VLANs.
