1.2 Flow Vision

Print Friendly, PDF & Email

This subject will be divided in two sections.

  1. Flow Monitor and Generator
  2. Flow Mirror

In FOS 7 the concept of frame-monitoring was introduced on Condor2 and Condor3 ASICs. This allowed an administrator to create a frame template based on the FC frameheader (see here) and obtain statistics on these frames. Flow Vision is somewhat progressing on this technology and has been extended significantly. Flow Vision is a 3 way solution which requires a switch capable of providing the functionality, software licensed to be able to configure and capture flows and a tool to collect and interpret these flows. All Condor 3 based switches (16G), FOS 7.4 and up, and Brocade Network Advisor 12.4.x are needed to be able to fully utilise the base flow-vision functionality. (The Brocade AMP platform is an extension but will be discussed later.)
