Hi,
I am using nfsen 1.3.6p1 on CentOS 5.9 x86_64 with nfdump 1.6.6.
I have noticed that only inbound traffic is recorded. The exporting
device is a Cisco 3825. Below is the IOS configuration as well as that
of one interface and its subinterfaces.
I thought that it is enough to set:
ip flow ingress
ip flow egress
ipv6 flow ingress
ipv6 flow egress
on the affected subinterfaces, but should I also/alternatively set:
ip route-cache flow
on the main interface?
Note: I only want a particular subinterface to export traffic (inbound
and outbound), not all subinterfaces.
May am I doing something wrong?
Can you please guide me? Any suggestions will be appreciated.
Thanks,
Nick
