LAN Emulation States
As defined in the ATM Forum LAN Emulation Over ATM specification, LE clients
enter various states of communication while attempting to join an emulated LAN.
These states (referred to as “phases” by the ATM Forum) indicate the progress of
an LE client as it connects with an emulated LAN (Figure 1-13
).
Figure 1-13. LAN Emulation States
Note:
The numbers that follow each state appear in the ATM LEC status
record (wfAtmLecStatusEntry).
Operational state (7)
BUS connect state (6)
Initial registration state (5)
Join state (4)
Configure state (3)
LECS connect state (2)
Initial state (1)
After experiencing
any failure, or
terminating its
connection to the
emulated LAN,
the LE client
returns to the
initial state.
If the LE client
loses the BUS
connection, it can
attempt to reconnect.
