Routers help connect networks within an organization or connect the networks of multiple branch locations. Which device do you use, and when do you use it? Both are primarily used to make connections between computers, networked devices, and even networks. A router is employed to settle on the littlest path for a packet to achieve its destination. Router offers a steady and reliable connection between network hosts. This will allow the connection of two hosts or a server and a host without the need for a hub between them. In contrast, switches (and hubs) are not capable of joining multiple networks or … This article was last updated on October 27, 2017. It actively manages the connections between the input port and the output ports, so you won’t run into the collision problem or any of the other issues that plague hubs. i want to ask about connection between switch and router. There are different ways to connect the PoE switch, router and PoE NVR. Connect another Ethernet cable to one of the ports on the back of the switch and connect the other end to the port at the back of the modem. A network switch learns the association between the MAC addresses of connected devices and its switched ports. So when only one PC is broadcasting, it will have access to the maximum available bandwidth. A switch, on the other hand, is much smarter. Router and Switch are both network connecting devices. Following are the important differences between Router and Switch. Whenever a switch port is made to configure or assign with a correct VLAN network, computer is then able to communicate through router interface and then will be able to access other VLANs in connection with the router. A wireless router allows wireless devices (e.g., your smartphone, tablet, wireless laptop) to connect to your network and the Internet. As the configuration will become increasingly complex, I suggest you read them in order. sorry for leaving that detail out..for the traffic to get from either switch to the router and back you will need to configure a routing protocol, static routes or a default route on both sw1 (reference the diagram in my previous response) and the the neighboring router. 1. VIPs) are configured on the same L3 device hosts from one VLAN should be able to ping hosts in another VLAN. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. It didn't work Question- The port(f0/24) on SW1 connecting to Router (f0/0) should be in trunk mode to carry all VLAN traffic to router from all 3 switches ? A router is typically connected to at least two networks, commonly two Local Area Networks (LANs) or Wide Area Networks (WAN) or a LAN and its ISP’s network — for example, your PC and your service provider. In networks the switch is the device that filters and forwards packets between LAN segments. Do you know why can'y I ping to router LAN from any switch and vice versa ? On all three switches I have created multile VLANs and assigned ports to these VLAN. The Router doesn’t know that it has two connections to the same switch — nor does it need to. After several minutes, the connection is ready to go. Some technicians have a tendency to use the terms router, hub and switch interchangeably. www.fiberopticshare.com/set-up-network-switch-with-router.html A router will typically include a 4 to 8 port Ethernet switch (or hub) and a Network Address Translator (NAT). I did what you recomended and I can ping from host to SW1 gateway with in each VLAN but can't ping to the router from any switch or host. If you only need to connect a few computers on one network, a switch is an ideal solution since they're cheaper than a router. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. The router has 2 FE ports one for WAN and one for LAN which is connected to F0/24 on SW1 which has unpruned trunk as suggested by you. The concept of distinguishing Hub and Switch to a Router is quite wrong. - also configure a VIP for management. A switch, however, keeps a record of the MAC addresses of all the devices connected to it. Rollover Cable - A 4-pair "rollover" cable. If for some reason this doesn't work for you...please let me know what type of device your router is and we should be able to figure it out at that point. The hub has no way of distinguishing which port a frame should be sent to. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Switches and routers are networking devices. Routers Help Connect Home Networks to the Internet Routers for home networks (often called broadband routers) are designed specifically to join the home network to the Internet for the purpose of Internet connection sharing. So, in short, a hub glues together an Ethernet network segment, a switch can connect multiple Ethernet segments more efficiently and a router can do those functions plus route TCP/IP packets between multiple LANs and/or WANs; and much more of course. All routers have a WAN Port that connects to a DSL or cable modem for broadband Internet service and the integrated switch allows users to easily create a LAN. -     configure L3 VLAN interfaces (a.k.a. Ethernet switches and hubs can be connected to a router with multiple PC ports to expand a LAN. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. On the router I will have route to all VLANs I have to createe on all these 3 switches. Some of the more high-end or business class routers will also incorporate a serial port that can be connected to an external dial-up modem, which is useful as a backup in the event that the primary broadband connection goes down, as well as a built in LAN printer server and printer port. In your above configuration...if the link is suppose to be an unpruned trunk I would remove the "switchport access vlan 100" configuration. For example: Your static routes on the router would be: ip route 192.168.10.0 255.255.255.0 192.168.1.2, ip route 192.168.20.0 255.255.255.0 192.168.1.2. I have read inter-VLAN routing i-e creatiing sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN? This type of cable is typically 3.05 m long but can be as long as 7.62 m. Normally, the connection order of the devices is modem -> router -> switch -> devices. Using headers and forwarding tables, routers determine the best path for forwarding the packets. then i choose port fa 0/24 and make it trunk. Routers are completely different devices. Multiple data cables are plugged into a switch to enable communication between different networked devices. create a layer 3 link between SW1 and your router...then use default or static routing on SW1 pointing to the IP of the routers connected interface. A router can connect networked computers to the Internet, so multiple users can share a connection. The switchport on the switch that connects to the router will be trunked. The Router operates like normal when routing packets between two networks. - this will also allow for the inter-VLAN routing...no need for router on a stick when using a L3 switch (e.g. Why Router Is Different And Better Than Hub And Switch. Today most routers have become something of a Swiss Army knife, combining the features and functionality of a router and switch/hub into a single unit. router and switch straight cable switch and switch crossover cable router and router crossover cable switch and pc straight cable thumbs rule similar devices cross cable different devices straight ... UTP Cable Crossover connection are used to connect two different devices, like routers and switches. SVI) for each VLAN with the respective IP address. Each serves as a central connection for all of your network equipment and handles a data type known as frames. Additionally, a 10/100Mbps hub must share its bandwidth with each and every one of its ports. Awesome Rettuc- Everythign worked as a chime   A big thanks for all the help provided!!! In this case, the cameras plugged to PoE switch will obtain IP address from the router … - configure a pruned trunk on the links from SW1 to SW2 and from SW1 to SW3 which allows only the VLANs which will be used on those devices, - configure UNPRUNED trunk ports from both SW2 & SW3 going up to SW1, - switch gateways can point to the management VLAN ip configured on SW1 (this gateway is used by the switch only and not any of the attached hosts). If, however, multiple PCs are broadcasting, then that bandwidth will need to be divided among all of those systems, which will degrade performance. What type of cabling do I use on the router to connect to the internet/ISP? Have you ever wondered what the difference is among these devices? In this case, the ADSL router and each computer connect to the switch, via a standard Ethernet cable.If you don't have an Internet connection, you can still set up a home network to share files, etc. I think that covers everything but if I left something out or you have any other questions let us know... Something you might want to also consider is leaving the VLAN interfaces configured on SW1 and instead of having a trunk link configured between SW1 and the router...simply configure it as a L3 link. Its job is to regenerate the … Routers make use of the alternative parts in case the main part fails to transfer data packets. Prior to Hotmail and its... Once a failure happens, repairs can be both costly. Some technicians have a tendency to use the terms router, switch and hub interchangeably, but have you ever wondered what the difference is? Thanks John- I have dropped the option to configure router on a stick as too many changes on the router side... All my switches are L3(Cisco 3560G). A router is a networking device that routes data packets between computer networks.
