Glossary

LECS

LAN Emulation Configuration Server. A LECS is an entity that assigns individual clients to particular ELANs by directing them to the LES that corresponds to the ELAN. There is logically one LECS per administrative domain that serves all ELANs within that domain.

LES

LAN Emulation Server. An entity that implements the control function for a particular ELAN. There is only one logical LES per ELAN, and it is identified by a unique ATM address.

Link-State Protocols

A series of routing protocols, such as OSPF, which permit routers to exchange information about the accessibility of other networks and the cost or metric to reach the other networks.

Lobe

In a Token Ring network, a lobe is a section of cable that attaches a device to an access unit.

LSA

Link-State Advertisement. A broadcast packet, used by Link-State Protocols, that contains information about neighbors and path costs. LSAs are used by receiving routers to maintain their routing tables.

MAC Address

Media Access Control Address. The MAC Address is a hardware address that uniquely identifies each node of a network.

MAC Layer

In IEEE 802 networks, the MAC layer is a sublayer of the Data Link Control (DLC) layer. The MAC layer interfaces directly with the network media. Each different type of network media therefore requires a different MAC layer.

MAC List

A list of MAC Addresses of devices that are allowed to access the network through the selected port. Each port can have a MAC List. If the port's security option is enabled, no device can access the port unless the device's address is on the port's MAC List.

MAN

Metropolitan Area Network. A data communications network designed for a town or city. Usually characterized by high-speed connections using fiber optical cable or
