What are Two Actions Performed by a Cisco Switch

A Cisco switch is a device that connects different computer networks together. It can be used to create a single, large network or to segment a large network into smaller ones. A switch can also be used to connect two similar networks so that they can communicate with each other.

Switches come in a variety of sizes and speeds, and they can be used for both wired and wireless connections.

As a network administrator, you are responsible for configuring and managing Cisco switches. There are two main actions that you can perform with a Cisco switch: manage traffic and monitor performance. Traffic management involves controlling the flow of data packets through the switch.

You can use Quality of Service (QoS) to prioritize certain types of traffic, or you can use access control lists (ACLs) to block specific types of traffic. Performance monitoring allows you to track the health of your network and identify potential problems. You can use tools like Simple Network Management Protocol (SNMP) to collect data about switch performance, or you can use packet sniffers to capture and analyze data packets as they flow through the switch.

What are the Two Actions Performed by a Cisco Switch

A Cisco switch is a device that connects multiple devices together on a single network. It does this by forwarding packets of data between the devices connected to it. A switch can also be used to segment a network into multiple smaller networks, or to connect two separate networks together.

A switch performs two main functions: address learning and frame forwarding. Address learning is the process by which a switch learns the addresses of the devices connected to it and stores them in its MAC address table. When a packet arrives at a switch, the switch looks up the destination MAC address in its MAC address table to determine where to send the packet.

If the destination MAC address is not in the table, the switch will broadcast the packet out all of its ports except for the port on which it arrived. This ensures that eventually all devices on the network will receive the packet, even if they are not directly connected to the same switch. Frame forwarding is simply forwarding packets from one port to another based on their destination MAC addresses.

In order for this to work correctly, each port on a switch must have an associated MAC address table that contains all of the addresses of devices that are reachable through that port. When a packet arrives at a port, the switch looks up its destination MAC address in that port’s associated MAC address table and then sends it out throughthe corresponding physical port.

How Does a Cisco Switch Work

In order to understand how a Cisco switch works, it is important to first understand the basics of networking. A network consists of two or more computers that are connected in order to share data and resources. In order for this to happen, each computer on the network must have a unique address so that the data can be properly routed.

The most common type of network is a Local Area Network (LAN). LANs are typically used in homes and small businesses because they are relatively easy and inexpensive to set up. A LAN usually consists of just a few computers, but can theoretically support up to 253 devices.

The speed of a LAN is also usually quite fast, with most connections being able to support data transfer speeds of 10Mbps or 100Mbps. Most home and small business networks use what is known as an Ethernet connection. Ethernet connections make use of special cables that transmit data using signals that are sent over twisted pairs of copper wire.

These cables connect directly from one computer to another, or from a computer to a router or switch. Routers and switches are devices that allow multiple computers to be connected together on a single network. They work by receiving incoming data packets from any connected device and then forwarding them out through all other connected devices until they reach their destination address.

Switches are similar to routers in that they allow multiple devices to be connected together on a single network; however, switches differ from routers in the way that they handle incoming data packets. Rather than forwarding every packet out through all other connected devices like routers do, switches only forward packets out through the specific port that is associated with the destination address contained within the packet header information. This process helps improve overall network performance because it reduces traffic congestion and eliminates unnecessary packet broadcasts throughout the network . . .

Cisco switches are some of the most popular types of switches used today due mainly due to their reliability and compatibility with many different types of networking equipment. Cisco switches come in many different models depending on your specific needs but all operate using basically the same principle described above . .

One feature that sets Cisco apart from other brands is its proprietary operating system known as IOS (Internetwork Operating System). IOS allows for much greater control over how your switch functions compared to other brands which often times can lead To increased security and performance levels . . Another advantage Cisco has over competitors Is its ability extend functionality by installing special software known as “packages” onto IOS..

Which is a Multicast Mac Address?

Multicast MAC addresses are special types of MAC addresses that are used for multicasting. Multicasting is a method of sending data to multiple destinations at the same time. It is often used for streaming audio and video data.

Multicast MAC addresses have a special bit set in the address, which indicates that the address is meant for multicasting. When a multicast packet is sent, it is sent to all hosts with the matching multicast address. This allows multiple devices to receive the same data without having to individually unicast the data to each device.

Multicast MAC addresses are usually written in hexadecimal notation with a “M” at the beginning of the address, such as M01:23:45:67:89:AB.

What is the Auto-Mdix Feature?

The Auto-Mdix feature is a great way to automatically configure your Ethernet connection. It can be used with both full and half duplex Ethernet connections. When you enable this feature, the router will automatically detect the type of cable you are using and adjust the settings accordingly.

This can save you time and hassle when setting up your network.

A Network Administrator is Connecting Two Modern Switches

A network administrator is connecting two modern switches in order to create a Local Area Network (LAN). The first step is to identify the type of switch that will be used. The most common types of LAN switches are Unmanaged, Managed, and Web-Managed.

Once the correct type of switch has been selected, the next step is to determine the port configuration. For example, an 8-port switch will have 8 Ethernet ports that can be used to connect devices such as computers and printers. After the port configuration has been determined, the next step is to select a cable type.

The most common types of cables used for LANs are twisted pair and fiber optic. Finally, the last step is to connect the two switches together using either a crossover cable or a patch cable.

What are Two Examples of the Cut-Through Switching Method

In computer networking, cut-through switching is a method for quickly forwarding packets to their destination. The switch starts forwarding the packet as soon as it arrives, without waiting for the entire frame to arrive. This reduces latency and can improve performance, especially in applications where low latency is important, such as voice over IP (VoIP) or gaming.

There are two main types of cut-through switching: fragment-free and fast forward. Fragment-free switches check the packet’s error control information (ECC) before forwarding it, to ensure that the entire frame will be received correctly. Fast forward switches do not check the ECC, but they do check the Media Access Control (MAC) header to ensure that the destination address is valid.

Both fragment-free and fast forward cut-through switching have their advantages and disadvantages. Fragment-free switches are more likely to drop damaged frames, which can help prevent errors from propagating through the network. However, this also means that they may introduce delays when a frame is dropped, which can impact real-time applications like VoIP or gaming.

Fast forward switches do not have this problem since they Forward Error Correction(FEC), allowing them to detect and correct errors in transit without dropping packets.

Conclusion

A Cisco switch performs two actions: forwarding and filtering. Forwarding is the process of sending data from one network device to another. Filtering is the process of discarding data that is not needed by the destination device.
