Configuring

Configuring
VLANs

Using

Cisco

IOS

Software

(ACE

Module)
Adding
Switched

Virtual

Interfaces

to

the

MSFC
A
VLAN

defined

on

the

Multilayer

Switch

Feature

Card

(MSFC)

is

called

a

switched

virtual

interface
(SVI).
If

you

assign

the

VLAN

used

for

the

SVI

to

the

ACE

module,

then

the

MSFC

routes

between

the
ACE
module

and

other

Layer

3

VLANs.

By

default,

only

one

SVI

can

exist

between

the

MSFC

and

the
ACE.
However,

for

multiple

contexts,

you

may

configure

multiple

SVIs

for

unique

VLANs

on

each
context.
Procedure:
Step
1
(Optional)
If

you
need
to

add

more
than
one

SVI

to

the
ACE
module,

enter

the
following
command:
Router(config)#
svclc

multiple-vlan-interfaces
Step
2
Add
a

VLAN

interface
to
the

MSFC.

For

example,

to
add
VLAN

55,

enter
the
following

command:
Router(config)#
interface

vlan

55
Step
3
Set
the

IP

address

for

this

interface

on

the

MSFC.

For

example,

to

set

the

address

10.1.1.1

255.255.255.0,
enter
the

following

command:
Router(config-if)#
ip

address

10.1.1.1

255.255.255.0
Step
4
Enable
the

interface.

For

example,

enter

the

following

command:
Router(config-if)#
no

shut
Note
To
monitor

any

VLAN

that

is
associated
with
more
than
two

trunk

ports,

physical

ports,

or
trunk-physical
ports

on

the

supervisor

engine,

enable

the

autostate

feature

by

using

the

svclc

autostate
command.
When

you

associate

a

VLAN

to

these

ports,

autostate

declares

that

the

VLAN

is

up.

When

a
VLAN
state

change

occurs

on

the

supervisor

engine,

autostate

sends

a

notification

to

the

ACE

module
to
bring

the

interface

up

or

down.
To
view

this

SVI

configuration,

use

the

show

interface

vlan

command.

For

example,

enter

the

following
command:
Router#
show

int

vlan

55
