Which Of The Following Is Not A Decision A Switch Can Make When Receiving An Incoming Frame?

What will a switch do if it receives an incoming frame and destination MAC address is not listed in the MAC address table?

If the destination MAC address is in the table, the switch forwards the frame out the specified port. If the destination MAC address is not in the table, the switch forwards the frame out all ports except the incoming port.

What decision does the switch make when it receives a frame?

In store-and-forward switching, when the switch receives the frame, it stores the data in buffers until the complete frame has been received. During the storage process, the switch analyzes the frame for information about its destination.

What happens when a switch receives a broadcast frame?

When a switch receives a broadcast frame, the switch forwards the frame out each of the switch ports, except the ingress port where the broadcast frame was received. Each device connected to the switch receives a copy of the broadcast frame and processes it, as shown in the top broadcast domain in Figure 1-22.

What will an Ethernet switch do if it receives a unicast frame with a destination MAC that is listed in the switch table?

What will an Ethernet switch do if it receives a unicast frame with a destination MAC that is listed in the switch table? The switch will forward the frame to a specific port. Switches use the transparent bridging process to determine how to handle frames.

What does a switch do if a MAC address Cannot be found in the CAM table?

What does a switch do if a MAC address cannot be found in the CAM table? The switch generates an ARP request for the address. The switch floods the frame out all ports (except the receiving port).

When would you configure VTP on a switch?

When would you configure VTP on a switch? When you have multiple switches with multiple VLANs and you want to share the VLAN database from one switch to all the others.

How do you connect multiple switches to best performance?

Just pick a port on both switches and use a patch cable to connect the switches to each other via these ports. And if your switch has ports with differing speeds, use the fastest ports to connect the switches to one another.

Where does switch send frame?

When a frame arrives at a switch interface, the switch looks for the destination hardware (MAC) address in its MAC table. If the destination MAC address is found in the table, the frame is only sent out of the appropriate interface. The frame won’t be transmitted out any interface.

What is frame in switch?

In packet switched systems, a frame is a simple container for a single network packet. If a receiver is connected to the system during frame transmission, it ignores the data until it detects a new frame synchronization sequence.

Do switches store data?

The switch will store this information in a MAC address table that it keeps in memory. When the switch has seen at least one frame from each connected device it will know exactly which MAC addresses that are connected to what ports, and it will then also be able to forward traffic only to the correct destination ports.

What will a switch do if the destination for a frame is not known?

When a switch receives a frame from a destination it does not know, it inserts the source mac address into its CAM table (a table which maps mac addresses to ports) and forwards the frame to all ports. The process of broadcasting a unicast frame is called unknown unicast.

What are the three different types of switch installations?

Different Types of Electrical & Mechanical Switches

  • SPST (Single Pole Single Through)
  • SPDT (Single Pole Double Throw)
  • DPST (Double Pole, Single Throw)
  • DPDT (Double Pole Double Throw)
  • 2P6T (Two Pole, Six Throw)
  • Intermediate Switch.
