LAG

Link Aggregation Groups (LAGs) provide a method of creating a high-bandwidth link. A LAG consists of a group of ports acting as a single logical port. All ports participating must have the same configuration.

LAN

Local Area Network. A high-speed, low-error data network that spans a limited area. LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area.

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.

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 other digital media.

MIB

Management Information Base. A database of network management information that can be monitored by a Network Management System. Both SNMP and RMON
