how I configure netflow on a cisco 877 router.
I have an interface e0/4 that is 172.1.1.1 on router one (network one) which links to another router (onnetwork two) which has an interface of e0/4 172.1.1.2 which allows two networks to communicate. Network one is 192.168.0.0 /24 and network two is 10.255.255.0 /24.
How do i configure netflow to monitor the traffic going through these interfaces?
I am trying to configure the NetFlow Top Talkers function on an ASR1002 with ADVENTERPRISEK9-M, Version 15.2(4)S. With this new Hardware and Software I am surprised to see that the command:
ip flow-top-talkers
top 50
sort-by packets
cannot be found on the CLI - it's just not there.
Is it possible to configure more than one layer 3 interface for netflow on a 3845? I can't seem to do it. Is there something I am missing?

View 5 Replies View RelatedI tried to configure netflow without success.
Setup is the following.
Cisco Catalyst 6509 with Sup720-10GE IOS 12.2(33)SHX7. There are around 30 L3 vlans configured on the switch. I'm only interested for the traffic on one L3 vlan which is the connection to wan cloud.
I wanna see only the traffic that goes to and come from the wan. On other Catalyst where I have routed interfaces i successfully configured netflow. I read a lot in the forums and documentations but i didn't find the right one.
I'm trying to configure a egress netflow in a 6500 (VSS) with VS-S720-10G supervisor. I foud some old posts and understood that netflow wasn't supported on 6500 but i found a new document and it seems that netflow is supported in Supervisor Engine 2T:[URL] Does the netflow still not supported in VS-S720-10G? It's weird because the command is supported:
#sh run int vlan 4

Any major difrrence between Netflow v/s Netflow-Lite?
I am trying to understand if Cisco 4948E can do the same job as Cisco 4500E or not and difference between Netflow v/s Netflow-Lite will work for me to select correct product.
I tried to deploy configuration templates with Cisco LMS Template Center, due to the 10 Cool LMS Tricks to better manage your network i am able to do it now.Just i don't know why, after deploying these templates the configuration is not save to the startup-config.another problem i have with the snmp-server location configuration. It seems my template does not support spaces in the textbox. Any way to put spaces in the snmp location?

View 1 Replies View Relatedi'm having some trouble pushing CLI templates to controllers in my lab. i get an invalid credentials error but it is random. sometimes i can push the template fine but 30 seconds later if i push the same template it will fail with error. several minutes later try it again and it fails. i have verified the credentials by reconfiguring them consistantly accrosss the devices but if the credentials were actually wrong it should fail every time, not intermittently. there are also 2 controllers i am testing this against and it is also random which controller fails. on the instances where i don't get the credential error my CLI template fully executes without error.
i am using WCS 7.0.230.0 on WIN2K and two 4400 controllers running 7.0.230.0.both controllers are configured with SNMPv3 and SSH. telnet and lower versions of SNMP are disabled.
We're using ISE's Sponsor/Guest Portal function.We customized the english default lanuage template.But we do not want to translate/customize all default language templates.How can I disable/remove the unwanted templates?

I have 5 WLCs and will do too the upgrade in the WLCs to version 7.2.130.0.
Will I lose some configuration with these upgrades ? Because the version 1.1.0.58 has more features than version 1.0.1.4 in the NCS and the WLC was adjusted some bugs.
The configurations that i has in the NCS version 1.0.1.4 is H-REAP and in the version 1.1.0.58 will be the FlexConnect, theoretically is the same, but i don't know if the configuration is the same in the two versions.
Can i do a downgrade in the NCS from version 1.1.0.58 to 1.0.1.4 if i have problems ? I was looking for a document who show how can i do this, but i didn't find nothing about.
I have configured the netflow to gathering flow from my cisco 2800 as below:

But i still not see users addresses(each individual hosts will go though) What and where i am configured wrong? I also attached here the map network.
configured the monitor and exporter on the wcs 5508 running 7.4.100.0 and it is not working.

View 0 Replies View RelatedI have an issue with Netflow that I have been unable to solve. I have an ASA5510 that is sending netflow data to a FogLight NMS and it works fine until I reboot the server. After the server is rebooted, the flows no longer are received until I reload the ASA. Once the ASA is rebooted, flows work fine. I can remove and reconfigure the netflow configuration on the ASA and that will start the netflow again, but that is painful.
Is there any way to easily stop/restart or re-initiate the netflow from the ASA easily?
I see these errors on my 6500 router which acts as my server farm and has hundreds of servers connecting to it. I have just taken over these routers from another guy and think the errors may have been there for quiet awhile. I have another router which doen't seem to have these errors. Can you tell me how to turn off netflow? Will it cause any problems to my server farm? Is there a risk to the router if I disable something?
I ask this cause the server guys are having problems with certain servers. I am not sure if they are because of this or not. I really would like to clear the logs. [code]
I was trying to get Netflow setup on one of my 7K VDCs and ran into a problem. While netflow data was reaching the collector, IP src/dst information was not appearing in the analyzer tool. I could not see any information about conversations. So I contacted the company that makes the collector/analyzer and the directed me to a blog on their site and told me to setup the 7K exactly as it is described in the blog post. I did and a bit later the ip src/dst address information appeared. So the only difference between the two configurations was that in the first case I tried to define a record and in the second case, no record was defined and instead the orginial-netflow parameter was used in the "flow monitor" section. [code]
I referenced the document "Cisco Nexus 7000 Series NX-OS System Management Configuration Guide,Release 6.x", Chapter 19 - Configuring NetFlow.It's clear to me that I didn't do something right in defining my own record since that's really the only difference between the config that worked vs the config that didn't. However, the documentation I referenced doesn't really provide useful information about how to create a record (above and beyond what I can already see by typing '?' at the CLI).
For example, the "match" command makes no sense to me. Usually when you have a match command it is accompanied by some sort of ACL. In the "flow record" section a match command would be something like "match ipv4 source address" but that's it. What does that mean? Match anything that has a IPv4 source address?? That doesn't make much sense. The collect commands are equally as bewildering. If I want to define my own record (and not use the original-netflow parameter) what do I need to do in the "flow record" sub-configuration to get Nexus to send ip src/dst information to the collector (which, I would think, is basic information to send - what good is netflow data without it)?
I have a question regarding netflow and NAT. I have read some documentation (on ASR1000) regarding monitoring NAT process on Cisco ASR1000 that can be done using netflow version 9 (the term was called netflow event logging a.k.a NEL). The problem is, I have not found the netflow collector that can do that. I have queried several software such as manage engine "Netflow Analyzer" and Lancope, but they said their software can not do that.

I've used the command "ip multicast net flow output-counters", but that is not enough, i guess. It is required to use further interface commands like "ip multicast netflow....", isn't it? But this commands are not available:

Recently bring up a new Router connected to ISP A and the Netflow collector/server is located in different location and they are connected to ISP B. I have enabled snmp and netflow config on my router(2911) but not receiving the netflow packets are not reaching the server for due to some strange reason whereas other packets like ICMP for snmp are reaching the netflow collector.Finally,I created GRE tunnel between the two locations routers and set the route for the netflow collector/server to the tunnel other end IP. In this way the netflow traffic are reaching successfully to the server.

I have a NME-NAM-120S in a 2811 running the same 5.1.2 code and it recognizes the RTP traffic including call information. Is that because the netflow data is different than the SPAN that the NME is receiving?
