What are two actions performed by a Cisco switch?
A cisco switch can either forward or block traffic. When forwarding traffic, the switch will determine the best path for the data to take based on the information it has. This ensures that data packets are sent to their intended destination quickly and efficiently.
If the switch needs to block traffic, it will do so based on predefined criteria. This can be used to prevent malicious traffic from reaching its destination or to ensure that only authorized users have access to certain network resources.
What is the role of MAC address in Switch?
The MAC address is used to uniquely identify a device on a network. This information is used by the switch to determine where to send data packets. When a packet is sent to a specific MAC address, the switch will forward it to the correct port so that it can be received by the intended device.
How does a switch know where data is?
A switch uses a process called ARP to determine where data is. ARP stands for Address Resolution Protocol, and it allows the switch to map IP addresses to MAC addresses. This way, when a packet arrives at the switch, the switch can quickly determine where it needs to go next.
In which Layer are these actions performed by a Cisco Switch?
A cisco switch performs these actions in layer 2 of the OSI model, which is the data link layer. This is the layer where data packets are sent and received over a network. The switch uses this information to determine how to best forward or block traffic.
What action will occur if a switch receives a frame?
Here are the three possible actions that could occur if a switch receives a frame:
- The switch could drop the frame.
- The switch could broadcast the frame to all ports.
- The switch could flood the frame to all ports.
