Hi,
I am trying to get Netflow going on some ASR1004s running
asr1000rp2-advipservicesk9.03.04.01.S.151-3.S1.bin. I started off
simple and did regular Netflow for IPv4 something like
ip flow-export version 9
ip flow-export destination x.x.x.x 5000
interface x
ip flow ingress
This worked for IPv4 but gave me no stats for MPLS labelled traffic so I
tried
ip flow-cache mpls label-positions 1 2
That didn't help at all.
I also wanted IPv6 Netflow and it seems that regular Netflow is not an
option so I have now moved to "Flexible Netflow" - something like the
following
flow exporter FE
destination x.x.x.x
transport udp 5000
flow monitor FM_IPv4
record netflow ipv4 original-input
exporter FE
flow monitor FM_IPv6
record netflow ipv6 original-input
exporter FE
interface x
no ip flow ingress
ip flow monitor FM_IPv4 input
ipv6 flow monitor FM_IPv6 input
So far I seem to be good for IPv4 and IPv6 but still am missing stats
for MPLS labelled packets. Does anyone know if MPLS-Aware ingress
Netflow is available in ASR1004/IOS-XE in either regular or Flexible
flavour? If anyone has a working example or can point to some doco that
would be great. From what I have seen I am suspecting that MPLS-Aware
Netflow may only be available in egress using standard no flexible
version???
Also an anyone confirm Flexible Netflow is the only way to get IPv6 flows?
Thanks
Ivan
