AirLive SNMP-24MGB User’s Manual
Media Access Control. MAC address provides Layer-2 identification for network devices.
Each Ethernet device has its own unique address. The first 6 digits are unique for each
device manufacturers. When a network device has MAC access control feature, only the
devices with the approved MAC address can connect with the network.
Mbps
Megabits Per Second. One million bits per second; a unit of measurement for data
transmission.
MiniGBIC
A type of Gigabit Ethernet module interface that uses SFP (Small Form-factor Pluggable)
transceiver. The MiniGBIC equipped with Switches typically comes with the MiniGBIC slot
for optional SFP optical transceiver.
Packet
A unit of data sent over a network.
Rate Control
It is an Ethernet switch’s function to control the upstream and downstream speed of an
individual port. Rate control management use “Flow Control” to limit the speed of a port.
Therefore, the Ethernet adapter must also have the flow control enabled. One way to force
the adapter’s flow control on is to set a port to half-duplex mode.
SNMP
Simple Network Management Protocol. A set of protocols for managing complex networks.
The SNMP network contains three key elements: managed devices, agents, and
network-management system (NMS). Managed devices are network devices that contain
SNMP agents. SNMP agents are programs that reside SNMP capable device’s firmware to
provide SNMP configuration service. The NMS typically is PC-based software that can
monitor and control managed devices remotely.
