Why
Use

Port

Channels?
A
port

channel

groups

multiple

physical

ports

into

a

single

logical

port.

This

is

also

called

port
aggregation
or

channel

aggregation.

A

port

channel

containing

multiple

physical

ports

has

several
advantages:

•
Improves
link
reliability

through

physical

redundancy.

•
Allows
greater

total

throughput
to
the
ACE
appliance.

For
example,

four

1-Gigabit

Ethernet
interfaces
can

be

aggregated

into

a

single

4-Gigabit

channel.

•
Allows
traffic

capacity

to
be

scaled

up

in

the

future,

without

network

disruption

at

that

time.

A

port
channel
can

do

everything

a

switched

port

can

do,


but

a

switched

por

t

cannot

do

everything

a

por

t
channel
can

do.

We

recommend

that

you

use

a

port

channel.

•
Provides
maximum

flexibility

of

network

configuration

and

focuses

network

configuration

on
VLANs
rather

than

physical

cabling.
