I am running into a road block getting Netflow up and running on a Cisco 871W. First the setup:
- Cisco 871W running IPSEC VPN to an ASA 5510.
- Netflow should be going to Solarwinds. (Their free tool).
- 871 is running 12.4 (15)T7.
I have added ip-route cache flow to VLAN1 (I also had it on interface FA04, but seeing conflicting reports that it should not be there?).
For Netflow also have the following:
ip flow-export source VLAN1
ip flow-export version 5
ip flow-export destination (server IP) 2055
sh ip flow export advises that 45009 flows have been exported in 4931 udp datagrams, 0 failures. However my graphical NetFlow tool shows nothing. At this point I am not sure if I am missing something. I had thought it might be VPN related (i.e. ASA is blocking) but other Solarwinds tools can connect and pull stats from the router in question.
I have never really used Netflow, so some help would be great.
NOTE: I see this command being recommended - ip nbar protocol-discovery. But when I try it in config, I get unrecognized command.
Thanks in advance.
