9A426-01/9A426-02 Module Specific Information

LEC Properties Screen Fields

The following information briefly explains each LEC Properties Screen field.

LECS ATM Address

Displays the ATM address of the LECS (if it is known), or the empty string.

LECS Configuration Direct VPI/VCI

A bi-directional, point to point connection set up by the LEC to get configuration information and the ATM address of the LES.

LEC ATM Address

Displays the ATM address of this LEC entry.

LEC ID

Displays the two-byte ID assigned to this LEC by the LES.

LES ATM Address

Displays the LES address for the ELAN of which this client is a member.

LES Control Direct VPI/VCI

A bi-directional, point to point VPI/VCI used by the LEC to issue LE_ARP requests and can be used by the LES to forward LE_ARP replies. This connection is maintained for the duration of the LECs participation in the ELAN.

LES Control Distribute VPI/VCI

An optional point to multi-point, or point to point connection. The LES uses this to forward LE_ARP requests that it cannot process. This connection is maintained for the duration of the LECs participation in the ELAN.

BUS ATM Address

Displays the ATM address of the Broadcast and Unknown Server or LAN Emulation Client whose MAC address is stored in ‘leArpMacAddress’.

BUS Multicast Send VPI/VCI

A bi-directional, point to point VPI/VCI used by the LEC to send broadcast, multicast and unknown unicast traffic to the BUS. This connection is maintained for the duration of the LECs participation in the ELAN.

BUS Multicast Forward VPI/VCI

A point to multi-point or a unidirectional point to point VPI/VCI from the BUS to each LEC. It is used by the BUS to forward traffic received from the LECS.
