Ethernet Frames
An Ethernet Frame with more than 1500 Bytes of data
What is a Jumbo frame?
48 bit binary value expressed using 12 hexadecimal values used to give a physical address to devices.
What is a MAC address?
table in which information is stored on the switch about the Ethernet Interfaces it is connected to on a network.
What is a MAC address table?
frame forwarding method which receives the entire frame and computes the CRC
What is Store-and-forward switching?
Frame that is flooded out all switch ports except the incoming port.
What is an Ethernet Broadcast Frame?
The result of a collision or unwanted signals
What is a Dropped Frame?
Vendor unique 6 figure hexadecimal code contained within a MAC address registered with IEEE
What is an Organizationally Unique Identifier (OUI)?
when a switch forwards out a frame on all ports in an attempt to find a MAC address
What is unknown unicast?
frame forward method which forwards the frame before receiving it in its entirety
What is Cut-through switching?
Frame received and processed by multiple hosts in the same host group
What is a Ethernet Multicast Frame?
Responsible for data encapsulation and media access control and provides data link layer addressing
What is the MAC Sublayer (802.3, 802.11, or 802.15)?
Process that a source host uses to determine destination MAC address associated with an IPv4 address
What is Address resolution protocol (ARP)?
Another name for a MAC Address table
What is a Content Addressable memory (CAM)?
variant of cut-through switching that provides the lowest level of latency
What is fast-forward switching?
Responsible for placing information in the frame to identify which network layer is used for the protocol
What is the LLC Sublayer (IEEE 802.2)?
A family of networking technologies defined in the IEEE 802.2 and 802.3 Standards
What is Ethernet?
Part of an ethernet frame that contains the Source and Destination MAC Addresses
What is an ethernet header?
The portion of a frame that is unreadable by an ethernet switch
What is the data portion?
Protocol that automatically detects the type of cable attached to a port and configure the interfaces accordingly.
What is auto-MDIX? (Automatic Medium-Dependent Interface)
Unique address that is used when a single frame is sent from a single transmitting device to a single destination device
What is a Unicast MAC Address?
Includes both source and destination MAC address to deliver the Ethernet frame from Ethernet NIC to Ethernet NIC on the same LAN
What is Ethernet Addressing?
The preceding marker to distinguish between decimal and hexadecimal.
What is 0x?
Forwards data packets by associating MAC addresses with specific switch ports.
Layer 2 Switching (Ethernet Switching)
variant of Cut-through switching that acts as a compromise between store-and-forward switching and fast-forward switching by performing an error check on the first 64 bytes of a frame to ensure there is no collision
What is Fragment-free switching?
A Layer 2 protocol that runs on bridges and switches with an IEEE specification of 802.1D that’s main purpose is to prevent loops when you have redundant paths in your network.
What is Spanning Tree Protocol (STP)?
