Andy thanks for your quick response.
The problem that I have is that in the main window of the NTA I never get the flows. There is some part of this window that says: Netflow Sources and over there I have the VDC of the Nexus and under the LAST NETFLOW RECEIVED label says NEVER so I'm not receiving anything. The configure of the Nexus is:
configure terminal
feature netflow
!
flow record ElektraIPv4Flow
description IPv4Flow
match ip protocol
collect counter bytes
collect counter packets
exit
!
flow exporter ElektraExportV9
description Exportv9
destination 10.63.33.56
source vlan 630
version 9
transport udp 9995
exit
!
flow monitor ElektraMonitorV9
description IPv4Monitor
exporter ElektraExportV9
record ElektraIPv4Flow
exit
!
interface vlan 630
ip flow monitor ElektraMonitorV9 input
ip flow monitor ElektraMonitorV9 output
If I show the Nexus outputs we will see flows to the Collector.
Thanks again
I see. That template is a flexible NetFlow implementation and won't work unless you also match
ip source, ip destination, tos, input interface, destination port, source port.
The default template for v9 includes these but I'm not sure how that is implemented for the 7K. For other platforms you just don't specify a template or any match/collect parameters.
The correct config for a 7k is as follows
flow exporter FLOW_NAME
destination 10.32.7.254 use-vrf management
transport udp 2055
source mgmt0
version 9
template data timeout 90
flow monitor FLOW_NAME
record netflow-original
exporter FLOW_NAME
if you use the record netflow-original command you dont have to create a flow record
I know this post is from February, but wondering about contexts and vlans in the 7k. we have several.
If I configure
flow exporter FLOW_NAME
destination 10.32.7.254 use-vrf management
transport udp 2055
source mgmt0
version 9
template data timeout 90
flow monitor FLOW_NAME
record netflow-original
exporter FLOW_NAME
If I dont create a flow record, will this basically capture everything or is this per context?
Im new to the 7k and Netflow so maybe Im asking an obvious question...
