I know the Nexus 5548P hardware does not support Netflow.I just need to know that if we introduce the layer 3 Daughter Board N55-D160L3 does this add Netflow support?

I am trying to use the following commands on the switch but it is not supported:
ip route-cache flow
ip flow-export destination
Attached is the output for show version and show module commands from the switch.
I need to know if Cisco Switch 2960 support Netflow. If it doesn't, how do I configure the switch to enable Netflow?

View 5 Replies View RelatedI'm looking at implementing a new DMZ and wanted Netflow capability for security monitoring.The architectural principles I have to adhere to dictate that the switches within the DMZ are layer 2 however to get Netflow I need a minimum of a 3560/3750X, Network Services module, IP Base IOS with ip routing and CEF enabled.To do this and still keep the switch functioning as a layer 2 device the intention was not to configure SVI's or any static/dynamic routing protocols.Will Netflow still work in that scenario?
View 4 Replies View RelatedI've been researching the 3750-x Netflow support but I'm not 100% sure of how much support it has. From what I've read the only way to get NetFlow support is to install a specific module that provides NetFlow. I also heard about how it might support s-flow but I haven't found out for sure.
View 8 Replies View RelatedI have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.
I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
Here some excerpts of what I´m saying:
PING results:
10000 packets transmitted, 10000 packets received, 0.00% packet loss
round-trip min/avg/max = 0.809/2.496/57.559 ms
System version: 5.0(3)N2(1)

The module just won't come up. Stays in off-line state. On two identical 5Ks, so its not hardware failure.Have the licenses and running code 5.0(3)N2(2).

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 just came to know Assurance feature license doesn't come for free when upgrading from LMS4.2 or NCS1.1. It has to be purchased. Before buying this license, i would like to know if IPv6 netflow is supported.

What are the limitations of Net flow v9 support on the 7600 platform for the SR code releases?
I know that Flexible Net flow is only available on newer releases with some newer hardware. Flexible Net flow gives you the ability to provide full support for Netflow v9 as well as IPFIX.
However, the documentation indicates that Net flow v9 is still supported in the SR code. So I am just trying to find out what are the limitations in how Net flow v9 is implemented without "Flexible Net flow". The Cisco TAC was unable to provide me any documentation about this.
I was working with Opmanager software to monitor my network, and i downloaded the Netflow plugin, i tried to enable the netflow on my core switch c3560 but I was surprised that it does not support the NetFlow, after many resersh most of URL's say it does not support until i found another URL from Cisco Says that it support Flexble netflow now, but i think we should update the IOS.

I currently have Netflow enabled on all of my routers in my network. However, I have a Cat3750, which does not support Netflow. The 3750 is at a larger remote site and I need visibility into the traffic that is traversing internal to that switch. All VLANs are configured on the 3750. I have an extra Cisco router, which I have theorized I could use as a Netflow probe.
The 2811 Router has to FastEthernet ports.F0/0 would be configured with no IP Address and would be connected to the 3750 on G0/1 with no VLANs configured.F0/1 would be configured with a static IP and connected to the 3750 on port G/02 with the appropriate VLAN to ensure network connectivity.
On the 3750, configure a monitor session with a destination of Interface G0/1.On the 2811, configure netflow to sent to the Netflow server and set F0/0 for ip flow ingress.Obviously, it doesn't work. But I cannot figure out why.
I searched around but did not see any valuable info on this so I guess it doesn't. But wanted to get confirmation from you guys.
View 2 Replies View RelatedI have a SR520 just deployed at a remote site with Internet Access.
Working Environment:
Remote sites have SR520 with IPSEC VPN back to HQ and netflow v.5 works through the VPN back to our PRTG server.
Non-Working:
I cannot get Netflow data to our PRTG with this first SR520 implemented with Zone Base Security. I am not able to get my netflow traffic out. VPN is up and running. Internet is a dialer0 interface. I have a Kron job that does the copy run to tftp backup daily to the same PRTG server and it works fine.
Both my source interface and address on the TFTP command and the netflow commands are the same interfaces (VLAN75) and IP. The Destination ip is the same too (through the VPN tunnel).

I am trying to figure out the Flexible Net-flow on Cat 4510R+E Switch running IOS-XE code. My Neflow flow software is manageengine 7.X. I am able to see the netflow interfaces but the traffic itself is not displayed. On the Switch I can see the netflow exporter statistics counter being incremented thereby confirming as being exported.

But the packet is not leaving the box. By setting up an ip sla monitor udp-echo I simulated some traffic (udp/2055) which is leaving the box.
