To enable netflow export on ASR1001, do i need the firewall feaure license or not ?Docs are not really clear, NBAR requires FW license, but i am unsure about Netflow?
View 1 RepliesI have a problem with the 6500 not exporting netflow data. They are not exported due to no fib.I have read somewhere that this has something to do with VRF. VRF are running on the router.ip flow ingress has been applied to desired ip int.Is there anything I could do to make it export netflow data?
VSS-core-XXX-rs1#sh ip flow export
Flow export v5 is enabled for main cache
Export source and destination details :
VRF ID : Default
Source(1) xxx.xxx.83.253 (Unknown)
[code]....
Is it possible to have one netflow export profile (may not be the right word...) to send all the flow information to one collector and another profile to only send traffic to and from centain IP addresses to another collector? If it is possible on the hardware and software, any quick sample config?

I am working with a Catalyst 4503-E with a Sup7-E. I'm trying to enable Netflow, and I have read the following guides: Catalyst 4500 Series Switch SW Configuration Guide, Release IOS ...
I have also enabled Netflow in IOS 12.1/12.2 and figured the process was similar (It seems to be). CEF is enabled, and I have all the pre-reqs according to the document above, however, the flow commands don't exist, they simply say "command unrecognized". I have included my sh version below.

(for example from site A)If it is not possible I think, I can rewrite my access lists and permit udp traffic from outside interface to server IP like this:access-list VPNACL permit udp host <Outside IP site A> host <Inside IP the Server> eq 9996,But I do not understand, what port I must be use in access list on Central site ASA. ,access-list VPNACL_A permit udp host <Inside IP the Server> host <Outside IP site A> eq 9996 ? or, in this place, must be source port in the udp netflow packet?

I have following requirements to implement on cisco asr1001 router.
1.G0/0/0 and G0/0/1 interfaces are connected to a swith through trunk. Multiple customers are will be using this trunk interface . Each customer will have subinterface with dot1q tag.
2 I want both sides of the ASR1001 to be in same segment .
3 If above two is possible I would like to implement shaping on each customers sub-interface level
is above implementation is possible on asr1001. configration and ios information. I found a technology called EVC . but I am not sure is that the one suited for me.

I want to copy a file from one ASR1001 and copy it to another. I ntried using tftp 32 but this is not going to work as the image is 315 MB.

How to enable Netflow on the ASA5540
View 10 Replies View RelatedI am working on Cisco 3550 switch on a certain requirement. I have got an access point connected to the switch and few mobile phones connected to the access point. I get the list of mac addresses connected to the switch ( Both access point's mac address & the clients addresses) by "show mac-address table dynamic" command. However, i am unable/confused to get the output of the following scenarios:
1. I would require to export the mac address from the switch to the local machine in any format (May be by using an SNMP tool, if available) so that the same needs to be used in my C# for development.What would be the way for the same ?
2. The mac address in the mac address table doesn't get updated dynamically. (Eg Scenario: A wifi client gets connected to an access point which inturn is connected to the switch, the mac address of the client shows up in the switch table. However if the client is disconnected, the client's mac address would still be displayed in the switch table )

I 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).
Snipped:
flow exporter prtg
destination x.x.x.x
source Vlan75

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.

It was running for at least a year: I was getting netflow packets on my analyzer from the box. Since a couple of weeks I get no netflow-packets anymore.debug ip flow export tells me "IPFLOW: Sending export pak to ... port 2055"
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.

Ive tried to configure NetFlow on layer 2 without success. I configured the recondmonitorexporter like the configuration guide said. but still i dont receive any netflow traffic. I checked the firewall on the VM and it looks fine.
i have done the command under the ethernet interface :" layer2-switch flow monitor TEST input" - for layer2 input.

I can't seem to find any information on the Nexus 5000 support of netflow. I assume that means it doesn't do 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?
