11 Cards in this Set

|
Autonegotiation |
An IEEE standard mechanism (802.3u) with which two nodes can exchange messages for the purpose of choosing to use the same Ethernet standards on both ends of the link, ensuring the link functions and functions well.
(Wendell, 2013 Sect. Glossary) |
|
|
Broadcast Domain
|
A set of devices that receive broadcast frames originating from any device within the set. Devices in the same VLAN are in the same Broadcast Domain
(Wendell, 2013 Sect. Glossary) |
|
|
Broadcast Frame
|
An Ethernet frame sent to destination address FFFF.FFFF.FFFF meaning that the frame should be delivered to all hosts.
(Wendell, 2013 Sect. Glossary) |
|
|
Collision Domain
|
A set of network interface cards (NIC) for which a fram sent by one NIC could result in a collision with a frame sent by another NIC in the same collision domain.
Wendell, 2013 Sect. Glossary) |
|
|
Cut-Through Switching
|
One of three operations for internal processing on some models of Cisco LAN
(Wendell, 2013 Sect. Glossary) |
|
|
Flooding
|
The result of the LAN switch forwarding process for broadcast and unknown unicast frames. Switches forward these frames out all interfaces, except the interface in which the frame arrived. Switches also flood multicast by default, although this behavior can be changed.
(Wendell, 2013 Sect. Glossary) |
|
|
Fragment-Free Switching
|
One of three internal processing options on some Cisco LAN switches in which the first bits of the frame can be forwarded before the entire frame is received, but not until the first 64 bytes of the frame are received, in which case, in a well designed LAN, collision fragments should not occur as a result of this forwarding logic.
(Wendell, 2013 Sect. Glossary) |
|
|
STP
|
Spanning Tree Protocol
A protocol that uses the Spanning Tree Algorithm, allowing a switch to dynamically work around loops in a network topology by creating a spanning tree. Switches exchange bridge protocol data unit (BPDU) messages with other switches to detect loops and then remove the loops by blocking selected switch interfaces. (Wendell, 2013 Sect. Glossary) |
|
|
Store-and-Forward Switching
|
One of the three internal processing options on some Cisco LAN switches in which the Ethernet frame must be completely received before that switch can begin forwarding the first but of the frame.
(Wendell, 2013 Sect. Glossary) |
|
|
Unknown Unicast Frame
|
An Ethernet frame whose destination MAC address is not listed in a switch's MAC address table, so the switch must flood the frame.
(Wendell, 2013 Sect. Glossary) |
|
|
Virtual LAN
|
A group of devices, connected to one or more switches, with the devices grouped into a single broadcast domain through switch configuration. VLANs allow switch administrators to separate the devices connected to the switches into separate VLANs without requiring separate physical switches, gaining design advantages of separating the traffic without the expense of buying additional hardware.
