CSMA/CD
Carrier Sense Multiple
Ethernet and Fast Ethernet.
Full Duplex
Transmission method that allows switch and network card to
effectively doubling the bandwidth of that link.
Port Trunk
Defines a network link
single high-speed logical link that combines several lower-speed physical links.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision domain regardless
of their physical location or connection point in the network. A
workgroup with no physical barriers, and allows users to share information and resources as though
located on the same LAN.
IEEE 802.1Q
VLAN Tagging—Defines Ethernet frame tags which carry
switches to assign endstations to different

IEEE 802.1p
An IEEE standard for providing

Port Mirroring

A method whereby data on a target port is mirrored to a monitor port for troubleshooting with a
logic analyzer or RMON
Bandwidth Control
This function allows the network manager to control the maximum rate for

limit traffic into or out of the network. Traffic that falls within the rate limit is transmitted, while
packets that exceed the acceptable amount of traffic are dropped.
