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:
This example shows how to enable NDE 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 export layer2-switched vlan 200
Displaying the NDE Address and Port Configuration
To display the NDE address and port configuration, perform these tasks:
This example shows how to display the NDE export flow source IP address and UDP port configuration:
Router# show mls nde
Netflow Data Export enabled
Exporting flows to 10.34.12.245 (9999)
Exporting flows from 10.6.58.7 (55425)
Version: 7
Include Filter not configured
Exclude Filter is:
source: ip address 11.1.1.0, mask 255.255.255.0
Total Netflow Data Export Packets are:
Command Purpose
Router(config)# ip flow export layer2-switched
vlan
vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
Enables NDE for ingress-bridged IP traffic in the specified
VLANs (enabled by default when you enter the ip flow
ingress layer2-switched vlan command).
Note NDE for ingress-bridged IP traffic in a VLAN
requires that NDE on the PFC be enabled with the mls
nde sender command.
Router(config)# no ip flow export layer2-switched
vlan
vlan_ID [- vlan_ID ] [, vlan_ID [- vlan_ID ]]
Disables NDE for ingress-bridged IP traffic in the specified
VLANs.
Command Purpose
Router# show mls nde
Displays the NDE export flow IP address and UDP port
configuration.
Router# show ip flow export
Displays the NDE export flow IP address, UDP port, and the
NDE source interface configuration.
