View all traffic on a switch port
I have Cisco Catalyst 6509 switch running in hybrid mode. On the CatOS side, I have the following configuration: set mls flow full set mls nde 172.22.22.24 9996 set mls agingtime long-duration 64 set mls agingtime 32 set mls agingtime ipx 32 set mls nde enable On the IOS (MSFC) side, I have the command 'ip flow-export destination 172.22.22.24 9996'. I can collect information for traffic routed across different VLANs just fine, but I don't see the traffic between two nodes in the same VLAN on the
Alerts based on 95percentile thresholds on interface utilization
I see that NFA already doesn't 95% thresholding, i was wondering we can generate alert based on auto threshold of 95%=, some thing similar to what we have under alerts and we can specify the % of bandwidth. Which is ok on low bandwidth circuits but for gig circuits and FE circuits they are never close to say 80% and it would make lot of sense i can generate alert saying that generate a major alert if bandwidth is >95% threshold for more than 10 minutes.

NFA reports All Routers TimeSync issues
Hi, When i go into NFA , it is reporting that all my routers are out of time sync, i have checked all the Routers and they are going to the same GPS SAT Time server as the NFA Server is. What could be causing this? Also i notice that everyday, NFA does not produce graphs or stats for a 8 minute period - allways between 10:10am and 10:18am Can you advise what i can do here ? Cheers, RH

Routing protocol reporting
Does Netflow analyzer professional 7.x support reporting for traffic on routing protocols such as ospf and eigrp? We do not see these protocols reported for interfaces running ospf. Is this data not exported in the netflow v5/v9 reports? We have tried using both v5 and v9. I assume that you can differentiate the traffic in v5 flows by the destination address of 224.0.0.5 or 224.0.0.6 (for ospf), however I do not see any netflow traffic reports destined to these multicast addresses either. Thanks
Multiple Interfaces on Interface View
I configured netflow on one port of a router and when i open up NetFlow Analyzer and looked at the rotuer it shows three interfaces that it is monitoring. All interfaces have inbound and outbound traffic. Why is three interfaces showing up when i only configured one on the router?
custom automated reports
does anyone have a recommendation for third part professional services to assist in writing/creating custom reports with netflow? Thanks
Netflow Analyzer 6.1 Build 6100 PDF reports graphs not looking correct
Anyone have this issue? Been using this feature for over 2 years and recently my PDF reports of interface activity (the graphs specifically) are looking goofy By that I mean, the colors that display in and out traffic are all messes up in the graph. When looking at the graph in the application, it looks fine, its just the PDF version is messed up. Any help would be appreciated. Thanks!
Support of QoS in NetFlow Analyzer EE 6.5
Hi All, Just wanted to know if QoS is supported in NetFlow Analyzer EE 6.5 (Build 6501); we have enabled the NetFlow configurations on Cisco 2821 router (Internet Router), the data is received but we see nothing in the QoS tab. Should we perform any addition tasks for viewing the QoS. Appreciate your response. Best Regards, Kris
difference in reported traffic
im using the trial on several vlan interfaces and notice a difference in the full list of applications and then the list of involved ip addresses in a certain application. i read something on granularity but that seems unable to explain a difference between 1.6 gig and 500mb in one day. so when i check a certain application in the full list i notice in the traffic column it says 1.6gig and when i select that application i only end up with 500mb in the traffic column. any clue what is going on here?
Netflow - differences in reports
Hello, We are running a trial version of Netflow Analyzer 7 professional. There seems to be a difference in the outputs from some of the reports. If click on 'conversations' link i get a big list of all the source and destinations for the specified time period. There are some pie graps at the bottom. If i open up the 'top source' pie graph it shows me that, for example 37% of traffic came from source IP address 10.4.5.98. However if i click on the 'sources' link that page shows me that source

Last hour is behind by 1 hour?
Hi Guys, Just downloaded the linux version of this program. I have a problem which has kind of stumped me.. Why is the program reporting the last hour wrongly, for example: On the dashboard I have last hour of data apparently From : Dec-18-09 06:08 and Dec-18-09 07:08, when in actual fact the real time here in the morning is 8:08am not 7:08am, also status also states that last netflow was recieved at 7:08am and not 8:08am, graphs also reflect this 'off by 1 hour'. The 'correct' last hour would be

Netflow 7 - 3 interfaces - license limitation
I was using netflow v5 (free) with my 857 router which managed 2 interfaces: bvi1 and vlan 1. When we got a new ISP, I replaced the 857 with an Cisco 877 and upgraded to netflow V7. It now monitors BVI1; Dialer0 and Virtual Interface2. BVI1 logs both in and out traffic Dialer0 does only in Virtual Interface does only out Due to budget and license constraints I only want to monitor 2 interfaces, like I always have, BVI1 and Dialer0. I anticipate a problem when the “trial” expires for the

License issue for Professional Plus.
We had NetFlow Analyzer Professional without date restrictions. Last year we purchased upgrade to Professional plus and we received license which is now expired. When we were buying upgrade, nobody mentioned that Plus licence is time based - we probably would not go for the upgrade in that case. How we can get Plus functionality back?
Billing per IP address
Hello I need to generate alerts when data transfer (download+upload) to one clinet IP address (for example 172.30.4.2) reaches 90% of maximum data transfer 2000MB. There is 100 clients like this, so I need to be notified by mail when everyone from clients reaches limit 90% fo 2000MB. Do I need only one billing plan with associated IP groups (one IP per IP group)? Or do I need 100 billing plans? Thanks for answer Mato
Problems Displaying a SubInterface in NFA
I'm not sure if anyone else has seen this issue but one of several 2821 routers I have doing NF exports, doesn't display one and only one, of the subinterfaces via NFA. The sub is up and up and I don't have this issue on any other 2821s but this particular router is picking up 4 interfaces not 5. It is not an issue of the sub being unmanaged, it simply doesn't display and i have no idea why. I'm running IOS 12.4(23) on this router. Thanks, Ron

Showing 3.5Mb/s sec over a T1 ???
For some reason in netflow analyzer sometimes i show over 3Mbits/s over a T1 connection, but when i do "show int s0/1" (the same interface) it shows the 5 min. average as 1.3MB's. I'm trying to figure out why its showing much more bandwidth at times than is actually going threw. Any Ideas?
Admin Operations Not Showing
Hi, I have all stuff configured (NetFlow 7 Professional) but some times we can't see the "Admin Operations" menu itens. I think this problem is related to a Java or JavaScript feature. When I'm using IE or Firefox, I have the same problem, and when I show the "Error Console" window in Firefox, it shows a lot of warning messages and one error message telling "objectRelesed not found". Do you have any idea, or possible troubleshot? Thanks.

NetFlow Analyzer - Accessing data from another application?
Is there a way to access the information externally via another application? For example we would like to pull reports on a per IP basis, how much bandwidth they have used over given periods of time? I realise your software may already do this, however we require this to be accessed via another internal application, and reports built of these. If this is possible, do you have any documentation on this?
useing the tool
can you use this tool on smaller home routers too?

Best Practices guide for Netflow
Hi, I've been using NetFlow for a couple months and I'm still not really sure how to use it to it's full potential. First, I'm not sure that everything is configured for best results. Which widgets are best to have for a "network snapshot"? Also, lets say I have a scenario where my network starts moving slowly. I open NetFlow, and assuming all my interfaces are sending NetFlow data, where do I start? What do I look for? I can see tons and tons of data, but I also seem to be missing some data. For

Currently all you offer is traffic utilization alerts. Please add additional thresholds, like speed, volume, error rate, conversation, error rates, protocols, etc. Also, a "Clear" notification is needed once the threshold is back within limits.

Need BGP Help
How can I see the AS number (not name)? How can I collect NetFlow information only for a single interface without changing the settings on the router? I don't want to impact out existing Netflow server. If I can't filter which interfaces I'm capturing NetFlow data for, how can I make a correlation between the interface and the AS that is sending the data? Long story short, I'm trying to optimize my BGP routes to favor links with higher bandwidth, but I first need to see what ASNs are hogging all
