Cisco Switching/Routing :: 7200 - Netflow / Packets Not Sent?

Jul 23, 2012

router 7200 (12.2(33)SRE1)
two interfaces with traffic going through, placed in a Data-VRF
Another physical interface and loopback interface in the global routing-table.
ip flow ingress on all physical interfaces configured
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.

Cisco Switching/Routing :: NetFlow / 6500 / Export Packets Were Dropped Due To No Fib?

Mar 13, 2012

I 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) (Unknown)

Cisco Switching/Routing :: 3750X Netflow Packets Are Not Being Exported To Server After Update

Feb 5, 2012

Basically I have netflow which i'm trying to use to export to a netflow collector. I'm pretty sure that the 3750-X does support netflow. I've recently updated IOS on the 3750-X to support flexi netflow.For some reason the netflow packets are not being exported to the server. I'm using Opmanager which should present the netflow stats in the form of a graph. I'm using a universal IOS image. (C3750E-UNIVERSALK9-M), Version 12.2(58)SE2 3750-X WS-C3750X-24T-S

Cisco WAN :: 7200 / Netflow On A Subinterface

Apr 19, 2012

I have a 7200 router with a 12.2.(46a) IOS and I am trying to activate Netflow on a subinterface. From the documentation of Cisco, I should be able to do it since the ios 12.2.(14)S but the command is unavailable.
I have tried also to enter the command in the subinterface directly but it doesn't recognize it.

Cisco WAN :: 7200 - Egress Netflow V9 And Output Packet Marking Order

Aug 17, 2011

when using egress netflow (v9) and output marking.
The topologie : Server <-----> R1 1>-----<1 R2 2>----<2 R3
R2 is a 7200 with c7200p-adventerprisek9-mz.124-15.T11.bin What I'm doing :- R2 forwards ping packets from Server to R3. When they arrive on R2, icmp packets are marked with CS3

- I change the DSCP to CS4 on R2 before forwarding packet to R3. I'm using for that an output service-policy on the R2-2 interface like this : interface ATM2/0.36 point-to-point

ip address
ip flow ingress
ip flow egress

Cisco Switching/Routing :: Netflow On SR520

Mar 18, 2013

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.
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).

flow exporter prtg
destination x.x.x.x
source Vlan75

Cisco Switching/Routing :: Netflow Support On 3560 / 3750X Platforms

Feb 8, 2012

I'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?

Cisco Switching/Routing :: Unable To Enable Netflow On Cat 4503-E (Sup7-E)

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.
sh version (edited):
Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSAL-M), Version 03.01.01.SG RELEASE SOFTWARE (fc1)
