Hi,
We have Cisco ASR1006 router with IOS asr1000rp1-advipservicesk9.03.13.01.S.154-3.S1-ext.bin, we have recently upgrade IOS from asr1000rp1-advipservicesk9.02.03.02.122-33.XNC2.bin.
After upgrading the IOS ip flow ingress and ip flow egress command is not working.
Please suggest on configuring NetFlow commands on this.
Regards

You need to change to the Flexible NetFlow feature as traditional NetFlow on ASR1K after 3.10S has been deprecated as per release notes at:

Also try this link, found if you follow the URL above, and I have made some notes about configuring inbound and outbound flow monitoring :-
That article was referred in these release notes but don’t follow the link in the release notes, use the link above as it seems to have moved;
The syntax I have used is almost the same, except that I don’t think you can quite have the 2 options they mention in the last line;
flow exporter FlowExporter1
destination 192.168.9.101
transport udp 9996
export-protocol netflow-v5
source FastEthernet 0/1
flow monitor FlowMonitor1
record netflow ipv4 original-input
exporter FlowExporter1
cache timeout active 1
cache timeout inactive 15
interface FastEthernet 0/1
ip flow monitor FlowMonitor1 [input|output] <<< with the netflow record above only input is ok
According to the command reference I looked at when you use the ipv4 ‘netflow’ flow record with ‘original-input’, it can only monitor inbound packets and vice-versa for ‘original-output’, therefore I think you need the pair of settings as we have done.
flow monitor FlowMonitor1
record netflow ipv4 original-input
flow monitor FlowMonitor2
record netflow ipv4 original-output
interface FastEthernet 0/1
ip flow monitor FlowMonitor1 input
ip flow monitor FlowMonitor2 output
