However if you do require devices on the Internet to connect into your network (often required by gamers) then you can configure port forwarding. Router1(config) #access-list 101 permit tcp 192.168.8.0 0.0.0.255 any eq 443 Securing your Cisco network by applying an access control list

After you have created an Access Control List (ACL), such as ACL 101 created above, you can apply that ACL to an interface. In the following example, this ACL is placed to restrict outbound traffic on FastEthernet0/1. Router1> enable Computer networking is a means by which computers are interconnected to share data and information, resources, and all other network devices such as printers. For example, if your company has 100 employees, and you have wired two Cat-5e cables to each user’s desk, you’ll need at least 200 1 Gb switch ports to support these users. You’ll also need a few extra ports for things like printers and Wi-Fi access points.

Configure a switch management interface for Cisco networking

This usually involves pressing a button on the wi_fi router and a corresponding WPS connection button on the Device. User EXEC mode: When you connect to a Cisco device the default configuration mode is user exec mode. With user exec mode you can view the settings on the device but not make any changes. You know you are in User EXEC mode because the IOS prompt displays a “>”. To create a standard ACL, you can use the following example which will create an ACL that allows traffic for the 192.168.8.0/24 network. Switch1> enable Installing a switch is usually very simple. Just plug in the power cord and then plug in patch cables to connect the network.

Having a good understanding of how your network fits together, and works is essential for successful troubleshooting. Questions and Answers Often, a distribution switch uses 10 Gbps ports rather than 1 Gbps ports. The added speed is helpful because each port on the distribution switch carries much more data than each port on the access switches. The access port switches should also be configured with a few 10 Gbps ports, which are used to connect to the distribution switch. Not all switches are created equal. Some switches are designed for very small networks in homes or single-office businesses. Small networks are so simple to manage that the switch itself doesn’t require any management or configuration of its own. You simply plug all the computers into the switch, and the network takes care of itself. MAN is a type of computer network that is larger than a LAN but not up to a WAN (Wide Area Network). It is an intermediary between LAN and WAN. It spans across more areas than in LAN and has a larger amount of computers; it can also be seen as a combination of more than one LANs. No node has any special role. This was the original networking model of windows networking. (windows for Workgroups)- Diagram below:In this tutorial you will learn the basic networking technologies, terms and concepts used in all types of networks both wired and wireless, home and office. Another common method, but not as simple is to use VLANs. See Understanding and using VLANs Connecting to Internet

If you are completely new to networking then the basic course will introduce you to the basic networking protocols used in small home/office networks and on the Internet. Sub Prompts: There are a number of different sub prompts from Global Configuration mode you can navigate to such as the interface prompts to modify settings on a specific interface, or the line prompts to modify the different ports on the device. How the nodes on a network communicate with each other can be very different to how they are physically interconnected.The home network diagram below shows the structure of a typical small home network using a wireless router and connected to the Internet. Of course, computers can exchange information in ways other than networks. Most of us have used what computer nerds call the sneakernet. That’s where you copy a file to a flash drive or other portable storage device and then walk the data over to someone else’s computer. (The term sneakernet is typical of computer nerds’ feeble attempts at humor.) This is the ability of a network to expand such that it gives room for more devices to be interconnected and integrated into the network without causing any major changes to the whole network. This is the networking model used on the web and the Internet and on modern large Windows networks.-Diagram below:
