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
engine - 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.
