Ch 10-Analyzing Ethernet LAN Designs Flashcards
An IEEE standard mechanism 803.u with which two nodes can exchange messages for the purposes of choosing to use the same Ethernet standards on both ends of the link, ensuring that the link functions and functions well
autonegotiation
A set of all devices that receive broadcast frames originating from any devices within the set.
broadcast domain
A set of network interface cards for which a frame sent by one NIC could result in a collision with a frame sent by any other NIC in the same domain
collision domain
The LAN switch forwarding process for broadcasts and unknown unicast frames. Switches forward these frames out all interfaces, except the interface in which the frame arrived.
flooding
A group of devices, connected to one or more switches, with the devices grouped into a single broadcast domain through switch configuration, gaining the advantage of separating the traffic without the expense of buying additional hardware
virtual lan (VLAN)
A wireless LAN device that provides a means for wireless clients to send data to each other and to the rest of the wired network, with the AP connecting to both the wireless LAN and the wired Ethernet LAN
access point
A device that cooperates with the wireless lightweight access point to create a wireless LAN by performing some control functions for each LWAP and forwarding data between the LWAP and the wired LAN
wireless lan controller (WLC)
A network topology in which endpoint on a network are connected to a common central device by point-to-point links
star topology
A network topology in which more than two devices can physically communicate and, by choice, all pairs of devices are allowed to communicate directly
full mesh
A network topology in which more than two devices could physically communicate but, by choice, only a subset of the pairs of devices connected to the network is allowed to communicate directly
partial mesh
A LAN device that provides a centralized connection point for LAN cabling, repeating any received electrical signal out all other points, thereby creating a logical bus.
hub
At what layer does a hub operate?
Layer 1
A networking devices that was a precursor to modern LAN switches. Forwards frames between LAN segments based on the destination MAC address.
transparent bridge
A campus LAN design in which the design does not use a separate set of core switches in a addition to the distribution switches
collapsed core design
In a campus LAN design, the switches that connect the distribution layer switches and to each other, to provide connectivity between the various distribution layer switches
core layer
