The

length-aggregation

TLV

advertises

whether

the

link

is

capable

of

being

aggregated

and

whether

it

is

currently

in

an

aggregation,

and

if

it

is,

the port

of

the

aggregation.

The

maximum

frame

size

TLV

advertises

the

maximum

supported

802.3

frame

size

of

a

sending

port

or

station.

In

accordance

with

a

non-limiting

example,

an

organiza

tionally-speci?c

TLV

is

used,

?lling

in

the

OUI

(0x00

0xA0

0xCA)

then

populating

the

de?ned

information

string

with

the

MAC

address

and

action.

An

example

is

a

frame

that

is

sent

from

one

network

device

and

meant

to

be

propagated

to

other

devices

via

LLDP.

The

“action”

may

be

for

the

receiv

ing

device

or

switch

to

obtain

relevant

data.

The

action

could

also

be

to

reply

to

the

originating

network

switch

with

infor

mation

about

the

MAC

address,

i.e.,

what

port

it

is

connected

to.

FIG.

4A

shows

there

is

an

LLDP

organizationally-speci?c

TLV

that

is

de?ned

so

that

an

organization

can

extend

the

LLDP

to

?t

their

needs.

The

OUT

(organizationally

unique

identi?er)

is

included

so

that

each

organization

can

differen

tiate

between

their

own

special

TLV’

s

and

the

organization’

s

TLV’

s.

This

special

TLV

is

used

to

de?ne

the

MAC

address

of

the

faulty

device.

As

shown

in

FIG.

4A,

the

TLV

type

equals

127

and

is

about

seven

bits

in

this

example.

The

TLV

information

string

length

is

about

nine

bits.

The

OUI

is

about

three

octets

and

the

organizationally-de?ned

subtype

is

about

one

octet.

The

organizationally-de?ned

information

string

is

about

zero

to

about

507

octets.

FIG.

4B

shows

a

frame

example

for

the

MAC

address

TLV

relative

to

the

LLDP

organizationally

speci?c

TLV

The

last

grouping

shows

the

action

and

can

include

additional

information.

There

now

follows

a

general

description

of

a

larger

IP

network

as

a

general

description

to

show

a

more

speci?c

and

larger

network

example

to

which

the

examples

as

described

can

be

applied.

FIG.

5

is

a

system

diagram

of

a

communica

tions

system

200

that

includes

various

network

components

and

devices

as

shown

in

FIG.

2

and

other

interconnected

platforms,

switches

and

platforms

or

servers.

It

should

be

understood

that

the

system

200

shown

in

FIG.

5

is

only

one

non-limiting

example

of

a

communications

system

that

can

be

used

with

the

methodology

as

described.

FIG.

5

shows

the

communications

system

that

includes

layer

2

and

layer

3

network

switching

functionality.

Typi

cally,

layer

2

switches

can

be

provided

such

as

the

NetVanta

1200

and

1500

series

switches

210

while

layer

3

Ethernet

switches

can

be

provided,

such

as

NetVanta

1300

series

devices

220

as

non-limiting

examples,

for

example,

the

Net

Vanta 1335

and

related

series

of

devices.

In

FIG.

5,

various

devices

such

as

a

1300

series

devices

by

ADTRAN,

INC.

are

illustrated

and

1200

series

devices

by

ADTRAN,

INC.

as

layer

2

devices

all

show

layer

2

and

layer

3

switching

and

functionality

in

this

non-limiting

example.

It

shouldbe

under

stood

that

a

Total

Access

multi-service

access

and

aggrega

tion

platform

(MSAP),

e.g.,

Total

Access

5000 from

ADT

RAN,

INC.

can

be

used

in

these

examples

with

network

modi?cations.

Switches

and

other

network

devices

as

illustrated

in

this

example

run

the

ADTRAN

Operating

System

(AOS)

and

provide

standards-based,

non-blocking

switching

and

sup

port

for

virtual

LAN’s

(V

LAN’s),

Quality

of

Service

(QOS),

and

Class

of

Service

(COS)

for

applications

such

as

VoIP,

link

aggregation,

advanced

management

and

remote

con?gura

tion

capability

and

other

functions.

The

devices

in

some

aspects

are

fully

managed

layer

2

and

layer 3

fast

Ethernet

switches

and

include

802.3af

Power

A

controller

manages

a

Access

Points

(WAP’s)

in

another

example.

These

Eth

ernet

switches

can

support

layer

2,

802.1p

Class

of

Service

(COS)

and

weighted

round

robin

and

strict

queuing

for traf?c

prioritization.

At

layer

3,

a

multi-service

router

supports

various

markings

and

class-based

weighted

fair

or

low

latency

queuing.

As

noted

before,

layer

2

switches

can

be

stackable

PoE

switches

with

gigabit

uplinks.

In

one

non-limiting

example,

a

Wireless

Access

Point

(WAP)

uses

a

NetVanta

150

wireless

access

point

(WAP)

or

NetVanta

1335

with

WiFi

that

provides

802.11

a/b/

g

radio

support

and

Virtual

Access

Points

(VAP’s)

and

segment

wireless

networks

together.

All-in-one

switch

routers

perform

services

such

as

switching,

IP

routing,

?re

wall,

Virtual

Private

Networking

(VPN),

and

802.11a/b/g

WiFi

in

a

single

platform.

A

NetVanta

1335

series

switch

integrates

a

modular

IP

access

router

and

24-port

PoE

layer 3

switch,

?rewall,

VP

and

appliance

and

wireless

access

in

a

platform.

Layer

2

switch-routers

can

be

all-in-one

access

platforms

such

as

the

NetVanta

1200

series

switch-routers

for

a

cost-effective,

single

box

approach

to

Voice

over

IP

(VoIP)

migration.

Layer

3

switching

is

provided

in

one

example

for

VLAN

trunking

and

VGRP

for

802.1Q

VLAN

functionality

and

provide

separation

of

broadcast

domains

and

functional

work

areas.

Other

communications

servers

could

be

used

in

the

illus

trated

networks

of

FIG.

5

such

as

a

NetVanta

7000

series

servers

and

devices

(including

NetVanta

7100

devices)

as

manufactured

by

ADTRAN,

INC.

of

Huntsville,

Ala.

The

communication

servers

are

an

all-in-one,

o?ice-in-a-box

that

provides

voice

and

data

solutions,

including

Private

Branch

Exchange

(PBX)

functionality.

SIP

communications

are

used

to

various

remote

sites

having

communications

servers

such

as

IP

business

gateways

in

other

examples.

Any

communications

servers

could

be

formed

as

a

single

chassis

and

provide

a

LAN-to-WAN

infrastructure

and

Qual

ity

of

Service

(QoS)

that

maintains voice

quality

and

includes

a

Graphical

User

Interface

(GUI)

for

network

set-up

and

facilitate

installation

and

system

administration.

In

this

example,

a

communications

server

allows

a

converged

IP

voice

and

data

network

with

a

full-function

IP

PBX

for

voice

such

as

a

NetVanta

7000

series.

It

includes

an

integrated

Power

Over

Ethernet

(POE)

switch-router

for

data

in

an

inte

grated

device

and

aVirtual

Private

Network

(V

PN)

for

secure

Internet

tunnelling.

The

device

enables

VoIP

by

providing

the

appropriate

functionality

that

includes

SIP-based

telephony

features,

voice

mail,

multi-level

auto-attendant,

caller

ID

name/number,

and

other

features

for

a

complete

VoIP

net

work.

The

device

includes

multi-site

SIP

networking

and

SIP

trunking

service.

Various

optional

modules

include

T1

and

ADSL

Network

Interface

Modules

(NIMs).

Analog

(FXS,

FXO)

Voice

Interface

Modules

(VIMs)

are

included

in

another

example

with

T1,

PRI

voice

interface

modules

and

?ber

SFP

modules.

A

communications

server,

in

one

example,

is

an

integrated

communications

platform

and

includes

capability

of

a

fast

Ethernet

switch

with

Gigabit

uplinks

and

expansion

slots

for

the

network

interface

modules

and

voice

interface

modules.

A

IP

telephone

system

as

part

of

the

communications network

200

as

illustrated

could

include

voice

mail

and

multi-level

auto-attendant,

caller

ID

name/number,

COS,

trunk

groups,

music-on-hold,

sales-on-hold,

overhead

paging,

and

other

call

options,

including

call

coverage

lists,

forwarding

of

calls

to

a

cell

phone

and

email

noti?cation

of

voice

mail.

Some

devices

can

operate

as

an

integral

SIP

gateway

with

the

appro

priate

FXS

and

FXO

analog

interfaces

to

support
