Virtual

Interfaces
You
can

configure

a

switch

virtual

interface

on

a

Multilayer

Switch

Feature

Card.

A

VLAN

defined

on
the
Multilayer

Switch

Feature

Card

(MSFC)

is

called

a

switch

virtual

interface

(SVI).

If

you

assign

the
VLAN
used

for

the

SVI

to

an

ACE,

then

the

MSFC

routes

between

the

ACE

and

other

Layer

3

VLANs.
By
default,

only

one

SVI

can

exist

between

an

MSFC

and

an

ACE.

However,

for

multiple

contexts,

you
might
need

to

configure

multiple

SVIs

for

unique

VLANs

on

each

context.
Trunk
Mode
How
the

interface

is

to

interact

with

neighboring

interfaces:

•
Dynamic—The
interface

is
to
convert

a

link
to
a

trunk

link

if

the

neighboring

interface

is

set
to
trunk

or

de

sirable

mode.

•
Dynamic
Desirable—The

interface

is

to

actively

attempt

to

convert

a

link

to

a
trunk

link.

The
interface
becomes

a

trunk

interface

if

the

neighboring

interface

is

set

to

trunk,

desirable,

or

auto
mode.

•
Static—The
interface

is

to

enter

permanent

trunking

mode
and
to

negotiate
converting

a

link
into
a

trunk

link.

The

interface

becomes

a

trunk

interface

even

if

the

neighboring

interface

does
not
change.
Desired
Encapsulation
Type
of

encapsulation

to

be

used

on

the

trunk

port:

•
Dot1Q—The
interface

is

to

use

802.1Q

encapsulation.

•
Negotiate—The
interface

is

to

negotiate

with

the

neighboring
interface
to

use
ISL
(Inter-Switch
Link)

(preferred)

or

802.1Q

encapsulation,

depending

on

the

configuration

and
capabilities
of

the

neighboring

interface.

•
ISL—The
interface

is

to

use

ISL

encapsulation.
Native
VLAN
VLAN
to

use

as

the

native

VLAN

for

the

trunk

in

802.1Q

trunking

mode.

VLAN

1

(1)

is

the

default
native
VLAN.
VLANs
VLANs
to

which

the

interface

belongs

(allowable

range

is

1-4094).

You

can

also

enter

ranges

of
VLANs,
such

as

101-120,

130.
Prune
VLANs
VLANs
that

can

be

pruned

(allowable

range

is

1-4094).

VTP

pruning

blocks

unneeded

flooded
traffic
to

VLANs

on

trunk

ports

that

are

included

in

this

field.

Only

VLANs

included

in

this

field
can
be

pruned.

You

can

also

specify

ranges

of

VLANs

that

can

be

pruned,

such

as

75,

121-250,

351.
