(Optional)
To

for

a

particular

Gigabit

table,

and

click

Details.
The

Carrier
Delay
Configurable
delay

at

the

physical

port

level

to

address

any

issues

with

transition

time,

based

on

the

variety
of
peers.

Valid

values

ar

e

from

0

t

o

120

seconds.

The

default

i

s

0

(no

carrier

delay).
Note
If
you

connect
an
ACE

to

a

Catalyst

6500

series

switch,
your

configuration

on

the

switch

may
include
the

Spanning-Tree

Protocol

(STP).

However,

the

ACE

does

not

support

STP.

In

this

case,
you
may

find

that

the

Layer

2

convergence

time

is

much

longer

than

the

physical

port

up

time.

For
example,
the

physical

port

would

normally

be

up

within

3

seconds,

but

STP

moving

to

the

forward
state
may

need

approximately

30

seconds.

During

this

transitional

time,

although

the

ACE

declares
the
port

to

be

up,

the

traffic

does

not

pass.

In

this

case,

you

should

specify

a

carrier

delay.
QoS
Trust

COS
Quality
of

Service

(QoS)

for

the

physical

Ethernet

port.

By

default,

QoS

is

disabled

for

each

physical
Ethernet
port

on

the

ACE.
QoS
for

a

configured

physical

Ethernet

port

is

based

on

VLAN

Class

of

Service

(CoS)

bits

(priority

bits
that
segment

the

traffic

in

eight

different

classes

of

service).

When

you

enable

QoS

on

a

port

(a

trusted
port),
traffic

is

mapped

into

different

ingress

queues

based

on

their

VLAN

CoS

bits.

If

there

are

no

VLAN
CoS
bits,

or

QoS

is

not

enabled

on

the

port

(untrusted

port),

the

traffic

is

then

mapped

into

the

lowest
priority
queue.
You
can

enable

QoS

for

an

Ethernet

port

configured

for

fault

tolerance.

In

this

case,

heartbeat

packets

are
always
tagged

with

CoS

bits

set

to

7

(a

weight

of

High).
Note
We
recommend

that

you

enable

QoS

on

the

FT

VLAN

port

to

provide

higher

priority

for

FT

traffic.
