No Traffic in a Client Environment.

Steps

to

Take:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Make

sure

that

each

LES

client

does

not

have

more

than 12

virtual

connections.

 

 

 

 

 

 

 

 

 

 

 

 

Problems

between

two

LAN-emulated stations, or between a

LAN-emulated

 

 

 

 

 

 

 

station

and

a

LAN

station located

behind

a bridge

(valid

only

for

IBM

proprietary

 

 

 

 

LAN emulation).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Steps

to

Take:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. For

performance

problems,

first

consider

the

frame

sizes defined

at

the workstation

level

and at the bridge level.

 

 

 

 

 

 

 

 

 

 

2. For

connection problems, first consider the Transcend ONcore

ATM

Campus

 

 

Manager

and

LAN

emulation

server,

which

can

provide you with

a

lot of

information

through

the

LES

monitor.

 

 

 

 

 

 

 

 

 

 

 

 

if you know neither the emulated MAC addresses of the stations nor the ATM addresses of these stations, use the ATMC Interface Configuration panel to get their ATM addresses.

Once you know either the ATM addresses or emulated MAC addresses of the stations, look at the Registered End-systems window of the LES monitor and check that your stations are registered.

Once you

know

which

station

is

NOT

registered,

record

its

ATM

address

and

look

at the Call Status History window of

the LES monitor. You should find a

recorded

call

from that

ATM

address

that

failedX, forreasonY'.certain 'cause

The

causeX shows you the Q2931 cause of the

failure. Refer

to

“Q.2931 Error

Codes for Clear Causes” on

page C-2.

 

 

 

 

 

 

 

 

 

 

If

you not find any call

from

that

ATM

address, that station has not been able

reach

the

LES.

Use

the

ATMC Statistics Control

Panel

to

open

the

Clear

Table

of

the

ONcore/4412SW

directly

attached

to the failing station (select 'Node' and

'Call

Logging'). That table should

have

entries

with

a source

ATM

address being

the

one of the failing station. You will

get

a

Q2931

cause of

the

failure. Ref

to

“Q.2931

Error Codes for

Clear

Causes”

on

page C-2.
