LEC Operation at Failure
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.
