Chapter 20 Flow-based Redirection
20.1 Introduction to Flow-based
Redirection
Flow-based redirection function enables the switch to transmit the data frames meeting some
special condition (specified by ACL) to another specified port. The fames meeting a same
special condition are called a class of flow, the ingress port of the data frame is called the
source port of redirection, and the specified egress port is called the destination port of
redirection. Usually there are two kinds of application of flow-based redirection: 1. connecting a
protocol analyzer (for example, Sniffer) or a RMON monitor to the destination port of
redirection, to monitor and manage the network, and diagnose the problems in the network; 2.
Special transmission policy for a special type of data frames.
The switch can only designate a single destination port of redirection for a same class of flow
within a source port of redirection, while it can designate different destination ports of
redirection for different classes of flows within a source port of redirection. The same class of
flow can be applied to different source ports.
