Chapter 2: System Configuration
LEC ID (Read-Only)
Displays the LAN Emulation Client Identifier of the active chassis LEC. The value displayed
in this field signifies the slot number of the 9A686-04 on which the LEC resides. If the LEC
ID field reads "0", it signifies that this LEC is not a member of an emulated LAN, and is not
connected to a LAN Emulation Server.
Actual ELAN Name (Read-Only)
Displays the name of the ELAN to which this LEC belongs.
LEC State (Read-Only)
Displays the current state of the LEC. The LEC goes through a series of initialization phases,
which may result in this field displaying different states as the initialization process proceeds.
The possible states are as follows:
In most cases, the initialization process occurs very rapidly, and the following
NOTE
initialization states, with the exception of "operational", may not display.
• initialState - While in initialState the LEC receives two types of configuration
parameters:
• From the User: LECS ATM Address, ELAN Name, MTU Size, and LAN Type.
• From the ATM Switch: The ATM Address of the switch.
• lecsConnect -
Direct VCC with the LECS.
The configure phase is where the LEC discovers the LES before going on to
• configure -
the join phase.
• join - During the join phase, the LEC establishes a Control Direct VCC with the LES.
After this connection is made, the LEC is assigned a LEC ID Identifier, is assigned the
name of the ELAN it will join, is notified of the maximum frame size allowed on the
ELAN, and the LAN type that is being emulated (IEEE 802.3). The initialization process
then proceeds to the initialRegistration phase.
• initialRegistration -
MAC Address(es) are unique before becoming fully operational on the network. During
this phase, the LEC may also register any additional unicast LAN destinations and Route
Descriptors.
While in the busConnect phase, the LEC connects to the Broadcast and
• busConnect -
Unknown server (BUS). At the end of this the phase, the LEC has a BUS Multicast Send
VCC and a BUS Multicast Forward VCC with the BUS. Once these VCCs have been
created, the LEC becomes operational on the network.
The LEC is now fully configured, and has joined the ELAN.
• operational -

The initialRegistration phase is used by the LEC to confirm that its
