Product Information

Your home router is your gateway to the Internet. When viewing your configuration some devices refer to it as the default router whereas other use the term default gateway. Your network design may end up with a total of five 48-port access switches, providing a total of 240 1 Gb ports to support the 100 users. When moving around in the Cisco IOS, you will see many prompts. These prompts change as you move from one configuration mode to another. Here is a summary of the major configuration modes: When working with your routers on your Cisco network, it’s very likely that you’ll want to have your routers route data. The first step in having your router pass data from one interface to another interface is to enable routing; just use these commands. Router1> enable Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.

If you plug one end of a cable into the port and the other end into a computer or other network device, the Link light should come on. If it doesn’t, something is wrong with the cable, the hub or switch port, or the device on the other end of the cable.Each of these topologies has advantages and disadvantages this Network topologies article has a really good overview of each topology along with advantages and disadvantages. Shared devices like switches and Wireless access points are network choke points just like traffic lights and roundabouts on a road. 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 “>”.

WAN: The second TLA you’re like to encounter is WAN. The WAN is part of the network that connects to the Internet. WAN stands for wide area network. (Okay, fine. Technically, WAN is the third TLA. The first TLA was LAN, and the second TLA was TLA. So that makes WAN the third TLA.) Internet: The Internet is a huge amalgamation of computer networks strewn about the entire planet. Networking the computers in your home or office so that they can share information with one another and connecting your computer to the worldwide Internet are two separate but related tasks. Today however most home and small business office networks will use a wireless network or mixed network, as most people use Smart phones, and tablets which don’t have Ethernet support.Note a new technology that uses mains cable overcomes many of these disadvantages. powerline networking is common on home/small office networks To create your wireless network, you can choose between three types of deployment: centralized deployment, converged deployment, and cloud-based deployment. Need help figuring out which deployment is best for your business? Talk to an expert.

This usually involves pressing a button on the wi_fi router and a corresponding WPS connection button on the Device.A network large enough to require more than one switch may also be large enough to require several distinct types of switches: In my experience most problems are easily diagnosed, and fixed with a little patience and perseverance. There are many different ways network nodes can be connected together. This isn’t normally a consideration in small networks but has networks get larger it becomes more important. Hub is also known as a multi-port repeater due to its similarity with the repeater, though there are specific devices called repeaters. The hub was also used to connect computers and share data amongst them, but it is now majorly used as a repeater to repeat signals from long distances. The hub is known as a layer one device (on the OSI model), likewise the repeater. Ethernet

This short video shows how to use a Wireless Home Hub ( BT) or router to create a home network that is connected to the Internet.The image below shows a typical network with four computers. You can see that all four computers are connected by a network cable to a central network device (in this case, a home router). This component, common in small networks, actually consists of three distinct but related network devices: What is variable-length subnet mask (VLSM)? - Definition from WhatIs ...." 17 Aug. 2014, https://searchnetworking.techtarget.com/definition/variable-length-subnet-mask. Accessed 7 May. 2019. ↩︎ Wireless networks use Wi-fi as the data link protocol. However other wireless options are being developed for the IOT (Internet of things). See Wireless networking Technologies for the IOT The following code will enable the Cisco proprietary Rapid Per VLAN Spanning Tree Protocol (PVST) over the open standard of Multiple Spanning Tree Protocol (MSTP). In addition to configuring STP on the switch, you will also configure port 2 on the switch for portfast, which allows the port to immediately transition to forwarding mode. Switch1> enable
