Configuring

Traffic

Policies
Class
Map

and

Policy

Map

Overview
The
traffic

classification

process

consists

of

the

following

three

steps:
1.
Creating
a

class

map,
which
comprise

a

set

of
match

criteria
related
to

Layer
3
and

Layer
4
t

r

affic
classifications
or

La

yer

7

pro

tocol

classifications.
2.
Creating
a
policy
map,
which

refers

to

the

class

maps

and
identifies
a

series
of
actions
to
perform
based
on

the

traffic

match

criteria.
3.
Activating
the
policy
map

and
attaching
it
to

a

specific

VLAN

interface

or

globally

to

all

VLAN
interfaces
associated

with

a

context

by

configuring

a

virtual

context

global

traffic

policy

to

filter
traffic
received

by

the

ACE.

defines

each

type

of

and

each

class.

You
create
class

maps

to

classify

the

traffic

received

and

transmitted

by

the

as

follows:

•
