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
