Hello,
I just joined a new company that has 7 remote MPLS sites that are all connected via Cisco 3750 Layer 3 switches and no routers in place.
Can I still use NETFLOW in this configuration and if so how ?
Thanks
Colin

Has ANYONE got Flexible Netflow working on 4500 with Sup7 that is understandable by Solarwinds Netflow
Hi have been trying to work with Cisco over the past 4 weeks to get Flexible Netflow to work properly with Orion/NTA with zero success. This is a 4507R+E with dual Sup 7's
I have the works TAC support person, but that's beside the point. I've spoken with SW and didn't get the warm and fuzzies on their answers either.
It appears to me I will not be able to monitor layre "virtual" interfaces on the 4507, which is unacceptable and if the case I will raise a stink with Cisco one I get it working.
So my questions are:
Does it even work? This hardware, Flexible Network and NTA 3.7?
The commands take and it just seems like NTA doesn't accept them, I'm guessing they are missing something like TOS, but this is not the same as regular Netflow.
I have been testing many permitations, but I either get the traffic in NTA showing that it is coming from all interfaces, or it doesn't see any at all.
Here's the config I am testing with today:
flow record ipv4
! match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect interface input
!
!
flow exporter NetFlow-to-Orion
destination 10.10.10.1
source vlan254
transport udp 2055
export-protocol netflow-v5
!
!
flow monitor NetFlow-Monitor
description Original Netflow captures
record ipv4
exporter NetFlow-to-Orion
vlan configuration 254
ip flow monitor NetFlow-Monitor input
Any help would be great

NTA Install
I have NPM, NPM additional web server, 4 pollers and NCM. NCM is 7.1 and is installed on the same VM that I have my primary NPM server is on.
I need to know if my upcoming install of NTA must be installed on the same VM which I have installed NPM or can I install it on a separate VM? i want NTA to intregrate with my primary NPM webserver and my additional NPM webserver just like my current install of NCM does.
Thanks,
Brad

Netflow Top Applications only showing "IPsec Nat-Traversal"
Hello
We have configured Flexible Netflow on a Cisco 871 router running version 12.4(20)T. The traffic is visible in the Orion Netflow tab, however the top conversations/applications show the following:
Ingress...99.43% of traffic is "IPsec Nat-Traversal", with the top conversation being between the static WAN IP address of our router and an IP address in the PTT network.
Egress...100% of traffic is "IPsec Nat-Traversal" between the same endpoints.
Any idea why we cannot see the real conversations?
Thanks

Netflow Interface details view
I went to the view for netflow interface details. I broke the view into 2 tabs. One for applications/hosts, the other for QoS. Now when I go into the interface I expect to get the same feel like a node where I see the 2 tabs on the side and I can pick on or the other and go back and forth. I can't do this. I have to go to the flow navigator and select 1 view or the other. Am I expecting this to work in the wrong way?

Nodes Traffic problem
Good morning,
I've recently taken over the management of the Solarwinds platform installed in this company. They've been using it for some time and they let it running after some basic configs and installs.
Now is my job to patch it properly and let it running in prime condition. However ive encounter some problems, for one with NTA(problems on our part im sure).
As you can see in the pic, most of the nodes addes have stopped sending data or have never sent it.
The config of those routers are all the same, and idk why is that they stopped sending data. If there is any pointer as to where to look up I'll appreciate it.
Happy monitoring,
Raul.

ASA 8.4(5) NetFlow Problem
After we upgraded our Cisco Asa firewalls to version 8.4(5), NetFlow exports from the Asa cannot be processed by Solarwinds NTA. The error is as follows:
NetFlow Receiver Service [SECUOMNF01] received an invalid V9 template with ID from device.
This problem started with Asa version 8.4(5), no problems in previous versions.
Asa flow-export configuration:
flow-export template timeout-rate 1
flow-export delay flow-create 30

Nexus 7000 netflow v5 issue
Using version 9 of netflow worked perfectly but I had to use v5 for another flow, now NTA is saying "NetFlow Receiver Service [SOLARWINDS] is receiving flow data from unmanaged interface '#103' on core and it does not support SNMP." If I add the interface its name is NTA Virtual Interface 101 and not the VLAN expected. What am I doing wrong?

Why the two numbers of Total bytes of Ingress Router A and Egress Router B are not equal???
Hi forum,
My Company has two site BachHO (**) and CTK3 (Branch). We connected two sites using an WAN. I monitored ingress and egress traffic of WAN interface of Router WAN at both sites. I suppose that in a specific of time the Total bytes of Egress of Router BachHO must be same as the number of Ingress of Router CTK3. But in reality, they are not same. I cannot find out the reason why??? Plz explain to me.
Here are some pictures
The two topmost pics are Router BachHO
The two bottommost pics are Router CTK3

CBQoS has no information
Hi forum,
I have configured class based shaping to my WAN interface of Router Wan. The Solarwind NTA has recognized the name of Shaping Queue and Class based Queues but no information in them. I has changed the selection to BOTH and Egress sometimes but not work. Do I miss some more configurations?
Thanks to any replies.

Polling a machine that does not broadcast
Hi Guys,
We currently have a machine or panel that has an IP address and is not pingable due to the way that it has been setup on the network. Because of this it is always showing to be down in Solarwinds. We have Solarwinds NPM Version 10.3.1 and NTA 3.10.0.
It is also not possible to install or enable SNMP on this device either(from what I've been told). Am I just SOL? or is there a way around this?
Thanks,
Shane

Netflow reports Error: NetFlowService inaccessible after server move
Hi
We recently did a server move of Orion NPM and NTA (database and website on same server)
After the move Netflow is now reporting "Error: NetFlowService inaccessible. Verify that service is 'Started'." but everything seems to be working fine and netflow data is coming in to Orion as expected.
Last Traffic Analyzer Events shows this:
NetFlow Receiver Service [OSYS-SC2] started - listening on port(s) [2055]
So this is not a critical error, i would just like to know if i somehow can get rid of the error message as everything appears to be working fine.

Trending traffic between IP address groups
I'm looking to find out how I could use NTA to trend traffic between different IP address groups. Ideally, I'd like to have a graph that represents traffic between two IP address groups over a specific period of time. Therefore, I could create a view with these graphs between various IP address groups. Is this at all feasible?

Any method to change the colors in pie charts for NTA?
Did a bit of searching but couldn't find this specific question asked.
Is there any method for having different colors display on the TopXX pie charts in NTA? Code/hmtl changes, etc....
Example of stock colors attached. The brown and gray are a little....muted.
Thanks!

Unmanaged Interfaces
Hello!
I am seeing a lot of the Netflow Data Received from Unmanaged Interface events on the NPM Web Console.
I have a doubt regarding this, is it possible to limit/block/cancel the output of the Netflow from a certain Interface? Do I have to do some configs on my switch/router?

Enable sFlow on HP Procurve 4208vl switch
We are implementing Solarwinds NTA and I'm trying to get sFlow working on our HP Procurve 4208vl switch.
I was able to enable sFlow by entering the following commands:
setmib sFlowRcvrAddress.1 -o 0A00020C (10.0.2.12)
setmib sFlowRcvrOwner.1 -D sFlowowner sFlowRcvrTimeout.1 -i 100000000
setmib sFlowRcvrPort.1 -i 2055
After entering "walkmib ifName" to get the PVID mappings - I entered these command to configure port C2:
setmib sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.54.1 -i 1
setmib sFlowFsPacketSamplingRate.11.1.3.6.1.2.1.2.2.1.1.54.1 -i 512
setmib sFlowFsMaximumHeaderSize.11.1.3.6.1.2.1.2.2.1.1.54.1 -i 128
setmib sFlowCpReceiver.11.1.3.6.1.2.1.2.2.1.1.54.1 -i 1
setmib sFlowCpInterval.11.1.3.6.1.2.1.2.2.1.1.54.1 -i 30
After any of these commands, the following message is returned:
sFlowFsReceiver.11.1.3.6.1.2.1.2.2.1.1.54.1: Unable to create.
Can someone help me to get this working?
Thanks in advance,
Steve

NTA 3.10.0 CBQOS Percentage question.
Question,
If you look at the attached file, at the very bottom on the far left. It shows the average for COS1_RTP s 0.12%. My question is, is that 0.12% of the total bandwidth for this interface or of the policy map percentages that are set?
Thanks!
