LEC Administration Screen Fields

The following information briefly explains each LEC Administration Screen field.

Configure LEC (Toggle)

Specifies whether the LAN Emulation Client should auto-configurethe next time it is started. Use theSpace Bar to select one of the following choices:

Automatic (default) - A client uses a LAN Emulation Configuration Server (LECS) to learn the ATM address of its LAN Emulation Server and to obtain other parameters.

Manually - Management tells the client the ATM address of its LAN Emulation Server (LES) and the values of other parameters.

NOTE

If you set Configure LEC to Automatic, do not write to any other attribute on the LEC Administration screen.

ELAN Name

The name of the ELAN to which this client is joined.

By default, the unit makes a LANE join request to the ATM network with the ELAN name blank (no entry). By popular LANE convention, Join Requests of this type will put that client into the first configured ELAN on the LECS (also known as the “default ELAN”). Assume this ELAN is named “ELAN1”. Once the device has successfully completed the Join process, all ATM-specificLocal Management screens will then reflect “ELAN: ELAN1”. This means that all Local Management screen information pertains to the “ELAN1” ELAN.

To set the device back to join the “default” ELAN, you must delete the current ELAN (ELAN1). After the current ELAN is deleted, a message is displayed that states that there are no longer any active ELANs. Now, you can move to the ELAN Name: field. Press the Space Bar, then theReturn key. HighlightSAVE and press theReturn key. This will cause the device to join the “default ELAN” again.

Since we support just a single ELAN, you cannot create a new ELAN unless all current ELANs have been deleted.

NOTE

Future releases will support multiple ELANs. Check your release notes to determine whether your release supports multiple ELANs.

If there are currently no active ELANs, then all choices on the ATM Specific Configuration Screen will result in the message “No ACTIVE ELAN present”. You can only access the Connection Table screen and the LEC Administration screen. You cannot access the LEC Properties screen, since there is no information.

Max MTU Size (Toggle)

The maximum data frame size that this client will use the next time it returns to the Initial State. Use the Space Bar to select one of the following choices:

1516 (default)

4544

LAN Type (Toggle)

The data frame format this LEC is using currently. Use the Space Bar to select one of the following choices:

802.3 (default)

802.5

LES ATM Address

The LES this client will use the next time it is started in manual configuration mode.

ELAN: (Modifiable)

Selects the ELAN for which attributes are to be displayed.

To select another ELAN, use the arrow keys to highlight the ELAN: field (bottom left corner of the screen), then press theSpace Bar.

PORT #: (Toggle)

Selects a specific ATM port.

To select another port (if applicable), use the arrow keys to highlight the PORT #: field (bottom left corner of the screen), then press theSpace Bar.
