NetFlow Traffic Analyzer (NTA)
NetFlow Setup Problem
sk_5910
Hi,
I'm pretty new to this & am trying out the NteFlow monitor in Orions (v8).
I have installed the NetFlow component to an existing Orion-v8 setup & the install process looked fine.
For some reason I am getting a yellow message in the NF Traffic Analyzer telling me:
NetFlow Receiver Service [NMA-ORION] is receiving a NetFlow data stream from an unmanaged interface on 172.16.0.226. The NetFlow data stream will be discarded. Please use the Orion System Manager to add Interface #11 in order to process this NetFlow data stream.
That IP address is a 2621 router that has all interfaces (S & FA) monitored in the NPM setup. NPM seems to work just fine looking at the data from the router. I am interested in the WAN data from the S0 interface, so I have setup the "ip route-cache flow" and "ip flow-export..." stuff for S0.
However, the message... & I don't know what it means by "Interface #11" anyway....
Can anyone help??
Thanks
Simon

I'm told they will be adding a feature to the upcoming release that will let you pick specifically which interfaces you want to accept data from on the netflow engine. Until then, I think the #11 refers to the IFindex value. You can pull this with an snmpwalker.

You can also run the following and get the if index number...example below...
sumcompanyswitch#sho snmp mib ifmib ifindex
EOBC0/0: Ifindex = 124
GigabitEthernet1/1: Ifindex = 1
GigabitEthernet1/10: Ifindex = 10
GigabitEthernet1/11: Ifindex = 11
GigabitEthernet1/12: Ifindex = 12
GigabitEthernet1/13: Ifindex = 13
GigabitEthernet1/14: Ifindex = 14
GigabitEthernet1/15: Ifindex = 15
GigabitEthernet1/16: Ifindex = 16
GigabitEthernet1/17: Ifindex = 17
GigabitEthernet1/18: Ifindex = 18
GigabitEthernet1/19: Ifindex = 19
GigabitEthernet1/2: Ifindex = 2
GigabitEthernet1/20: Ifindex = 20
GigabitEthernet1/21: Ifindex = 21

You can also use the EE toolset "MIB Browser" to find the if index.
Use MIB "IF-MIB:ifXTABLE" (1.3.6.1.2.1.31.1.1) to view the info for your router/switch. It will give you the index correlation to the slot/port.

If you right click on an interface in the Orion System Manager and select Interface Details you will also be able to see the if index

This selection feature is available in NTA 2.0.
