One of our customers recently invested in a Cisco Nexus 7000.  Raul (Plixer Field Engineer) visited the customer last month and had his picture taken in front of the switch just after it was installed:

Why Datacenter Customers should Invest in Flexible NetFlow on the Nexus:

  • System scalability of up to 500,000 (with 95 percent
    utilization efficiency) cached flows for forwarding
  • Effective hardware-based sampling to improve
    NetFlow table utilization
  • Capability to create and track bridged IP flows
    Support for NetFlow Export Version 5 (the most used)
    and NetFlow Export Version 9 (the most flexible)
  • Sampled NetFlow: (similar to sFlow) Effective hardware-based sampling to improve and preserve NetFlow table utilization;
    capability to implement full NetFlow on critical
    interfaces while implementing sampled NetFlow on
    other, less critical network portions
  • Egress NetFlow and Bridged NetFlow: Useful to track
    flows within a VLAN
  • TCP flags: Now exported as part of the flow information;
    very useful in understanding TCP flow directions and
    detecting denial-of-service (DoS) attacks

Scrutinizer v7 supports Flexible NetFlow.

Michael is one of the Co-founders and the former product manager for Scrutinizer. He enjoys many outdoor winter sports and often takes videos when he is snowmobiling, ice fishing or sledding with his kids. Cold weather and lots of snow make the best winters as far as he is concerned. Prior to starting Somix and Plixer, Mike worked in technical support at Cabletron Systems, acquired his Novell CNE and then moved to the training department for a few years. While in training he finished his Masters in Computer Information Systems from Southern New Hampshire University and then left technical training to pursue a new skill set in Professional Services. In 1998 he left the 'Tron' to start Somix which later became Plixer.
