Catalyst 6509 NetFlow Support

Catalyst 6509 NetFlowCatalyst 6509 NetFlow support is essential, especially when the switch is set up as a core network device; this blog should help you get started with NetFlow traffic monitoring on 6500 series switches.

Enabling NetFlow on a 6509 is slightly different from the traditional IOS NetFlow setup. Here you need to keep in mind that NetFlow on the MSFC is collected in software, and on the PFC it is collected in hardware.  Beside the familiar IOS NetFlow commands,  Cisco 6509 NetFlow also requires enabling NDE in order to export flow statistics to the collector.

NetFlow Collector: System Requirements

Posted in NetFlow Analysis on May 3rd, 2012 by Jimmy W
NetFlow Collector: System Requirements

System requirements for a NetFlow collector are a lot higher than the average program. While I am still the “new guy” in support I am already seeing some trends here at Plixer. The majority of cases I have been working with involve servers that seem to run slow despite being on top of the line equipment. Nearly every time this issue comes up it is caused by an improper hard disk configuration.

One of the most overlooked NetFlow Collector System Requirements that write heavy database servers have is disk IOPS (Input/output Operations per Second). You have to remember that a spinning disk is very limited on how many writes it can make at any given time, and if the collector cannot write to the disk fast enough it can cause a lot of problems.  This has been the root cause of a lot of slow NetFlow collectors.

Vyatta: NetFlow Support

Vyatta NetFlow Mononitoring

has been improved in some of the latest VC 6.x releases. I worked on a NetFlow reporting issue with a VC 6.0 user in the past trying to figure out why his NetFlow Analyzer was not showing the expected amount of traffic. We used Wireshark and found that a large number of flow packets were being exported without flow data, therefore were useless and discarded by the collector. Since he upgraded to VC 6.2, he was able to see all his traffic.Vyatta now supports MAC addresses, as seen in the image below! Read more »
