Table D-4 Last LEC Failure Reason

State

Possible Causes

Possible Solutions

None

The LEC is either
inactive or has
successfully completed
the operation.

None required.

Timeout

A task could not be
completed within
its allotted time
frame.

The software has been
set up to use a LECS,
but a LECS is either not
present on the network
or broken.

The LES for the ELAN is
not functioning
correctly

If there is a LECS on
your network, ensure
that it is operational
and on part of the
network that can be
accessed by the ATM
Module.

If a LECS is not present
on the network, you
must enter the LES
Address for each ELAN
manually using the ATM
VLAN Setup Screen
(see “Extending VLANs
into the ATM Network”

on page 8-4).

Contact Technical
Support.

Undefined Error

An error has
occurred but no
cause can be
identified.

Unknown.

Contact Technical
Support.

Version Not
Supported

LANE 1.0 not
supported.

The LANE services you
are trying to connect
to, do not support
LANE version 1.0.

Ensure that the LANE
Services use LANE 1.0.

Invalid Request
Parameters

The LES/LECS has
rejected a request
from the LEC
because the request
parameters were
incompatible with
the ELAN.

The LEC may be
requesting a resource
that is on an ELAN
which has a different
LAN type to the LEC.

The frame size used
could be wrong.

Check the underlying
media for both the
ELAN and the LEC
requesting the service.

Check the frame sizes
being used.

Duplicate LAN
Destination

A destination source
MAC address
duplicates a
previously registered
MAC address.

The LES has received a
request from a LEC
which contains a MAC
address already
registered to another
LEC on the same ELAN.

You may have
accidentally entered the
same MAC addresses
twice.

Ensure that MAC
addresses are unique.
