A switch forwards Ethernet frames in a LAN primarily through two functions: MAC address learning and frame forwarding. It maintains a MAC address table by learning the source MAC addresses of incoming frames and associating them with the corresponding switch ports. When a frame is received, the switch looks up the destination MAC address in its table to determine the appropriate port to forward the frame, ensuring efficient data transmission within the network. If the destination MAC is unknown, the switch will broadcast the frame to all ports except the one it originated from.
What else can I help you with?
Why are Ethernet II frames preferred over Ethernet 802.3 frames on contemporay lans?
They can support multiple higher-layer protocols, and Ethernet 802.3 frames cannot.
Why are Ethernet II frames preferred over Ethernet 802.3 frames on contemporary Lans?
a. because they can support multiple higher-layer protocols, and Ethernet_802.3 frames cannot
Why are Ethernet 11 frames preferred over Ethernet 802.3 frames on contemporary LAN?
because they can support multiple higher-layer protocols
How does an Ethernet switch forward a broadcast frame?
it s connected by the bridge network connection
What gets sent on a cat5 cable?
Usually Ethernet frames.
What layer does an Ethernet switch operate?
An Ethernet switch operates primarily at Layer 2 of the OSI model, which is the Data Link layer. It uses MAC addresses to forward Ethernet frames to the correct destination within a local area network (LAN). By managing data traffic efficiently, switches help reduce collisions and improve overall network performance. Some advanced switches can also operate at Layer 3, performing routing functions based on IP addresses.
What are the minimum and maximum sizes for Ethernet frames?
It would be 46 and 64 bytes.
Can you transport Ethernet over SONET?
Yes, Ethernet can be transported over SONET (Synchronous Optical Network) using a method called "Ethernet over SONET" (EoS). This technique encapsulates Ethernet frames within SONET frames, allowing Ethernet data to be transmitted over SONET links while taking advantage of SONET's high-speed, reliable transmission capabilities. EoS facilitates the integration of Ethernet services into existing SONET networks, enabling service providers to offer Ethernet services over long distances.
Does an unmanaged switch have its own MAC address?
yes i think, because the MAC address is the physical address which is assigned by the vendor of the Ethernet card. ** Improved Answer ** No, Unmanaged switches do not have a MAC address. All they do is filter, forward or flood frames.
What is the PPPOE protocol about?
The Point-to-Point Protocol over Ethernet or the PPPOE is a network protocol for encapsulating PPP frames inside Ethernet frames. The PPPOE term is something used confusingly to refer to either a modem to router protocol and/or the DSL side of things.
How are data frames identified and sent to the correct VLAN when exiting an Ethernet trunk?
Based on the VLAN tag.
What causes lost frames on Ethernet?
You might have poor connectivity. The wire could be marred in some way.
