ATM VLAN LEC Status 9-7
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.

Duplicated ATM
Address
A source ATM
address duplicates a
previously
registered ATM
address.
The LES has received a
request from a LEC
which contains an ATM
address already
registered to another
LEC on the same ELAN.
For example, if a LES is
faulty, when a LEC
disconnects from the
LES, the LES might fail
to register the change.
When the LEC tries to
rejoin the LES, the LES
still has that LEC’s ATM
address in its database,
and thinks that two
devices have the same
ATM address.
You may have
accidentally entered
the same ATM
addresses twice.
Ensure that ATM
addresses are unique.
Check the LES
database for duplicate
addresses.
