Configuring

Network

Access
Configuring
Port-Channel

Interfaces

for

the

ACE

Appliance
The
disadvantage

of

a

port

channel

is

that

it

requires

additional

configuration

on

the

switch

the

ACE

is
connected
to,

as

well

as

the

ACE

itself.

There

are

many

methods

of

port

aggregation

implemented

by
different
switches,

and

not

every

method

works

with

ACE.

For

an

example

of

how

to

configure

a

Cisco
Catalyst
6500

switch

to

enable

a

port

channel

connection

to

ACE,

see

the

“Configuring

a

Catalyst

6500
Series
Switch

for


an

ACE

Appliance

Port-Channel

Interface

Connection”

section

on

pa

ge

12-38 .
Using
a

port

channel

also

requires

more

detailed

knowledge

of

your

network's

VLANs,

because

all
“cabling”
to

and

fr

om

t

he

ACE

will

be

handled

over

VLANs

rather

t

han

using

physi

cal

cables.
Nonetheless,
use

of

port

channels

is

highly

recommended,

especially

in

a

production

deployment

of
AC
E

.

Configuring
a

Port-Channel

Interface
Note
This
feature

is
for
ACE

appliances

only.
You
can

group

physical

ports

together

on

the

ACE

appliance

to

form

a

logical

Layer

2

interface

called
the
port

channel.

All

the

ports

belonging

to

the

same

port

channel

must

be

configured

with

same

values;
for
example,

port

parameters,

VLAN

membership,

and

trunk

configuration.

Only

one

port

channel

in

a
channel
gr

oup

is

allowed,

and

a

physi

cal

por

t

can

belong

to

a

single

port-channel

interface

only.
