Login problem - "null"
Hi. I'm evaluating NetFlow Analyzer (build 4011), and after a week of running I got a problem with logging in. After I enter any valid username and password, all I get is the Login screen again, but with a line "null" above the input fields. Thanks. sameky
Dropped Netflow Datagams
Hello, Is there a way to determine and/or report on the number of Netflow datagrams that have been dropped between the exporting router and the NFA server? If I'm not mistaken, Netflow datagrams contain sequence numbers that can be used for this purpose. Thanks
Problem with PRI interface
We have a Cisco 3745 router running IOS 12.2(15)T12. It has a PRI interface on it and we have several dialers set up. I enabled netflow on only the fast ethernet interface on this router initially but noticed that Netflow Analyzer saw all the dialers on this router. After a while we noticed that Netflow Analyzer was only showing outbound traffic for all the dialers. I then put the "ip route-cache flow" statement on one of our dialer interfaces. I then noticed that when i did "show ip cache flow"
Dropped Packets
I just installed NetFlow Analyzer 4 (4011). I would like to be able to get graphs of dropped packets from the input/output queues. Is this possible? Does NetFlow Analyzer have the capability? Does a cisco router with netflow enable even export that data? Thanks, Chris
Grouping interfaces on Multiple Routers
I am currently evaluating several different Netflow reporting Products. I like the look and feel of this product (using the on-line demo). One requirement I have, is to be able to group interfaces from different routers into one report page. I have a fully meshed backbone with 2 routers at each site for redundancy. In order to view all the traffic in & out of a site, I need to be able to select 4 interfaces on 4 different routers (2 for in & 2 for out). I do not want to select the WAN & LAN interfaces
Feature request!
Hi, I don't know how doable this is, but: Let's say I'm on the "Application tab" for a given interface, with the nice graph and the table of applications underneath. When I click on an application, I drill down to see source/dest IP addresses, etc. My feature requests are: - To see both source and destination ports in the table, like you'd see in a custom report. Perhaps "Source Port" and "Dest Port" could be added to the "Group By" dropdown to enable you to show the kind of table we have at present.
Netflow Analyzer Traffic Volume problem
Dear Agerald, Thank your support for us so long time. We still are at customer site. The customer challenge the product's accuration. Because we do a testing with the customer. Our testing case information as follow: 1. ftp a large file - 10GB from sun solaris host: 10.166.1.1 to another solaris host: 10.166.4.4 we set up two IP group for the two IP monitor. After 30 minutes, we found the result as follow: 10.166.1.1 traffic out volume: 2209MB 10.166.4.4 traffic in volume: 2081MB For the result,
Licensing for Virtual Interface
I apologize in advance if this has been posted before I am evaluating NetFlow Analyzer and so far have been impressed. I would like to know how licensing works when using virutal interfaces. I have a Cisco 7200 router with over 400 ATM sub-interfaces. How many licensed interfaces are required in this scenario? Additionally, would this same licensing scenario apply to VLAN interfaces on a Cisco 65xx? Thank You
Graphing top talkers over time
I have been trying the evaluation version of the product and I would like to know if it is possible to graph the top talkers over time. Thanks
Innaccurate application graphs
I am trying the evaluation version of the product and I have noticed that the application graphs are very erratic. For example, if I look at Utilization on the "Last Day Report" and compare it to the Traffic graph, the application graph is more than 50% lower than traffic. However, if I switch to the "Last Hour Report", then the utilization goes back to around where it should be. (except it is has a 10 minute resolution instead of 1 minute). In addition, the "Last hour Report" is often truncated,
Graph resolution?
I have been trying the evaluation version of the software and I would like to know if it is possible to see greater resolution on the application graphs. It appears that 10 minutes is the highest detail level that you can see. Thanks,
PDF-Export since 4011
Since the last Update (4011) we have "PDF-Export" only in the consolidated report, all other reports are without the PFD-Export-Button.
ESP-APP
I can't find esp in the apps, but it is showing up in application reports, i'm guessing its something like ipsec, can someone give me some insight as to what this app is.
NetFlow Analyzer cisco port name
For my netflow analyzer testing environment. we have enable a cisco 6513 and send netflow version 5 to netflow analyzer. But I found that its portname is ifindexYYY and not be GX/Y etc. But in OpManager, the portname is right. my cisco 6513 for the configuration of netflow as follow: global configuration: enable netflow via cisco 6513 loopback I want to confirm whether it is necessary to enable every port and send netflow to this software instead of sending netflow via cisco 6510 loopback interface
Source or dest port?
Hi, In the image below, is "Port" the source or destination port? Also, did 192.168.88.11 initiate the flow, or is this just return traffic on a flow initiated by the destination machine? many thanks, alec

Unkown interface names with Enterasys SSR-8600
Hi, I am using Netflow with Enterasys SSR-8000 and SSR-8600. I have configured Netflow correctly with SNMP-Communities and all known interfaces of the routers are shown. Beside the "normal" port-names I get every day new ifindexXXX-port-names which can not be resolved. E.g. a router has 81 physikal and logical interfaces, but netflow reports ifindex82 and up to ifindex255. Every day I get new ifindex-entries between ifindex82 and ifindex255. I tried to read the mib with the troubleshooting-tool SnmpWalk.bat
Access NetFlow Analyzer from FireFox
Dear, I have already install and running Netflow Analyzer(NFA) in my PC under Linux. It seems to be fine. But why I can't access NFA with Mozilla Firefox? Is NFA doesn't support FireFox? But if I access NFA with IE 6, everything is normal. Thank you. Regards, Stevanus
SP1 Installation problem
I am having difficulty getting sp1 applied to build 4002 on a windows 200 server I have followed the online instructions, i.e shutdown netflow service (used control panel) extracted the files in SP1 into c:\adventnet\me\netflow and then ran BackupDB.bat to copy the mysql data files. Then ran updatemanager.bat, selected the sp1 .ppm file, and tried to install. It attempts to install, but fails with an error, (Unspecified) and then does a cleanup after failure. I have attached the log for the session.
Migration of database from 4.0.0 to 4.0.1
Is it possible to migrate data from our old Netflow Analyzer box that is running 4.0.0 build 4002 to our new box running 4.0.1 build 4010? I don't want to turn the new box on and the old one off until I can make sure I won't lose any data. I tried to copy over the mysql\data directory from the old box to the new, but this did not seem to work (got no response from the webserver when i tried to connect)

1 of 10 Ports not working
We have a router with 10 ports which sends his netflow packets to Netflow Analyzer. Only 9 Ports arrive there. The only difference to the working ports is that this port has compress stac configured. Could this be the reason, and if not, is there any tip for this? cu - Reinhart

Cisco Port Name Problem Again
The portname still have some problem. Because I install the netflow analyzer in the same machine with opmanager and snmp configuration is the same. But Opmanager can show ifindex and portname accurately. But the netflow analyzer can only show ifindex. Please tell me how to be able to enable the product to find the accurate portname. You can send email to me and I will reply some relative information via the email address: franklfc@iei-china.com or contact with me via MSN account: franklfd@hotmail.com

Hi Can anyone tell me if this product can give feed back on AS information from the router - origin-as etc? Thanks Harry

Interface Naming
Is there any way to modify the default interface name (i.e. Serial 2/0) to a more descriptive name? (i.e. To Location B) I have my interfaces set with descriptions, but it doesn't appear to pull that from SNMP. Thanks!
No router detected
Hi, i'm using the Linux trial version of Netflow Analyser but no router is detected. My cisco router conf seems to be correct since tcpdump indicates netflow frames are coming with the correct parameters (port, src address, srv address). If anyone has a solution, please tell me. Thanks. Best regards

Net flow Analyzer Shuts Down

Filter in/out flows that have a destination interface of 0
Hi, It would be useful if we could filter in or out flows that have a destination interface of zero (i.e., traffic aimed at the router itself, or traffic dropped by an ACL). From a security perspective, being able to filter out all flows dropped by an ACL means that all you're left looking at is traffic forwarded by the router. Seeing traffic that was dropped by an ACL might lead you to investigate something that never happened! Likewise, looking at traffic that was dropped by an ACL (destination

Address Grouping - more information or feature request
In the feature list of 4010 we are running there is: 1. Address Grouping - Create monitoring and reporting groups based on IP addresses or applications If I give a look at the "All IP Groups - Dashboard View", I like to see how much bandwidth is using one particular group of ip (1 group equals 1 range in our configuration) but how can it be revelant or useful because it is not linked to any router? Can you give me some information on that please?... I think a very interesting feature is the ability
Service Pack 1
A couple of questions:- We have just installed service pack 1 on Netflow Analyzer 4 build 4002 and everthing works except ive noticed that in the about box it still says build 4002. Is this correct? I overwrote all existing files with the new files from the service pack ZIP file so i assume its been upgraded. I was under the impression the service pack updated build 4002 to 4010? Also the new script to backup the database. Ive run this and noticed it just zips up all the stuff in the mysql\data directory.
Bug with SP1, Change Router-Name not possible
Hi, I am testing NetFlow. Yesterday I installed the SP1 and now every time I want to change a Router Name and click Update, the name is reset to the SNMP-Router name. It is not possible to set a unique, better readable name for a router now, if the SNMP-Community is activated for this router. If I delete the Snmp-Community for a router, I can change the name for this router to whatever I want. But this is not what I want. Regards, Manuel
