Chapter 14 Flow-based Redirection

14.1 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.

14.2 Flow-based Redirection Configuration Task Sequence

1. Flow-based redirection configuration

2. Check the current flow-based redirection configuration

1. Flow-based redirection configuration

Command

Explanation

Physical Interface Configuration Mode

access-group <aclname> redirect to interface

[ethernet <IFNAME>|<IFNAME>]

no access-group <aclname> redirect

Specify flow-based redirection

for the port; the

no

access-group <aclname>

redirect” command is used to

delete flow-based redirection.

2. Check the current flow-based redirection configuration

Command

Explanation

Global Mode/Admin Mode

show flow-based-redirect {interface [ethernet

<IFNAME> |<IFNAME>]}

Display the information of

current flow-based redirection

in the system/port.
