Configuring NDE
Enabling NDE for Ingress-Bridged IP Traffic
In PFC3B or PFC3BXL mode with Release 12.2(18)SXE and later releases, NDE supports
ingress-bridged IP traffic. PFC3A mode does not support NDE for bridged IP traffic.
Note
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. The exported
bridged flows will have ingress and egress VLAN information and not the physical port information.
NDE is enabled by default when you enable NetFlow on the VLAN. To disable NDE for ingress-bridged
IP traffic in VLANs, perform this task:
Command
Router(config)# ip flow export layer2-switched
vlan vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
Router(config)# no ip flow export layer2-switched
vlan vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
This example shows how to enable NDE for ingress bridged IP traffic in VLAN 200:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# ip flow export layer2-switched vlan 200
Displaying the NDE Address and Port Configuration
To display the NDE address and port configuration, perform these tasks:
Command
Router# show mls nde
Router# show ip flow export
This example shows how to display the NDE export flow source IP address and UDP port configuration:
Router# show mls nde
