ATM VLAN LEC Status 9-9
LEC Operation at Failure Identifies the operation
that was being carried out when the LEC setup failed.
This field should be used in conjunction with the Last
LEC Failure Reason to identify the cause of the
problem. The possible operations are shown in
Table 9-4.
LE_CONFIGURE
Error
This state may be
given to refuse a
service without
giving a specific
reason.
The information
provided by the LEC
may be invalid.
You may have entered
an invalid ELAN name.
As this state is used to
indicate a range of
problems, you should
check the other states
and solutions
described in this table.
If this does not resolve
the problem contact
3Com Technical
Support.
Check that the ELAN
name is correct, and
the ELAN has been set
up correctly.
Insufficient
Information
The LEC has not
provided sufficient
information to
allow the LECS to
assign it to a specific
ELAN.
The MAC address may
be invalid.
The LEC may be
requesting a resource
that is on an ELAN
which has a different
LAN type to the LEC.
You may have entered
an invalid ELAN name.
Check that each MAC
address on your
network is unique.
Check the LAN type
used.
Check that the ELAN

Operation Description
None There are no known operation failures.
Calling LECS The LEC is trying to connect to the
LECS to receive LANE configuration
information.
Reading
Configuration
from LECS The LEC receives configuration
information from the LECS in
preparation for joining the LES.
Joining LES The LEC is trying to join the ELAN by
registering itself with the LES that
controls that ELAN.
When the LEC has joined the LES, it is
given a unique LAN Emulation Client
Identifier (LECID), knows the Emulated
LAN’s maximum frame size, and knows
its LAN type (either Ethernet or Token
Ring).
Initial Registration After joining, a LEC can register any
number of MAC addresses and/or
Route Descriptors (for Token Ring
implementations).
Connecting to BUS In order to establish a connection to
the Broadcast and Unknown Server
(BUS) the LEC requires the broadcast
address. It requests the broadcast
address from the LES.
Operational The LEC is now part of the ELAN.
