can a hub be replaced with a switch

One problem with hubs is the unnecessary traffic due to the spammy transmission process. With a hub all workstations are essentially on the same wire and every port sees every packet. Switch 100 Mbps 8 ports can manage until 800Mbps of band-width. The network is now working, and I have been able to identify some of the cables and have labeled them. (This was a network I inherited) Ran a scan and found the run was 645 feet. A hub 100 bases-T 100Mbps offer of band-width divided between all the PC, some is the number of ports: The total band-width is determined by the number of ports on Switch. This conversation is currently closed to new comments. But I do have one annoying prob. You can then Telnet to the hub and determine which of those devices are connected to which port. Traffic entering one port is forwarded to all other ports. Hubs are an OSI "layer one" device. As a consequence, the hub introduces more collision than the switch. Put in an ethernet extender and it now works like a champ. Please remember to be considerate of other members. A hub is the easiest and least expensive way to construct a network of personal computers together. Rather than use a crossover cable (whichis discussed in the next section, "Cables Connecting Hubs andSwitches"), you can use the more simple straight-through cable (alsodiscussed in … Please enable Cookies and reload the page. If you're new to the TechRepublic Forums, please read our TechRepublic Forums FAQ. The Hub in a network is a device that has multiple ports in it. He was setting up a bundle of computers in our conference room and he was networking two computers in the board room. Since Ethernet is a base-band technology (meaning only one device can transmit at any given moment) collisions are going to increase rapidly as you add additional devices or interlinked hubs. You may need to download version 2.0 now from the Chrome Web Store. The one thing that swithes do is mac-learning that sets them apart from Hubs. A virtual LAN can be created using a Switch and it can also work as a multi-port bridge Usually comes with 24 to 48 ports Transmits Frames (layer 2 … What does an Ethernet switch do? Depending on the type of networking switch, it can segregate data and send only the data intended for a particular PC to that PC. This will return the associated IP and MAC addresses of all devices on the network. (j/k)As he has NOT told us what the brand and model of the old or new equipment is, it is hard to tell what is going on here.I DID run into this problem last summer. John said he will use a switch for the conference room computers and a hub for the two computers in the board room. D. A switch decreases the number of broadcast domains. If your IP address begins with 192.168. it;s likely that you’re already behind a router, and can simply use a switch or hub. A switch is a control unit that turns the flow of electricity on or off in a circuit. That makes the hub inefficient - in a hub, only one computer can transmit at a time.Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports. The differences between hub, switch and router is a confusing term for users. A switch on the other hand is not a repeater but actually a bridge, which acts upon the content of the Ethernet frame it receives and forwards the frame to the appropriate port on the switch. All the steps as listed complete OK and if I end up with the re-configured HH4 connected to my Mac’s LAN port alone with a regular LAN cable I can access the HH4 on its new IP address (as long as I configure the Mac’s IP address setting manually with the ‘router IP address’ set to the HH4 IP address). would it really be dependent on if there is a downstream hub? Years ago I had a small server backbone network running on a 100Mb hub. A way to map out the network, put the hub back in and get a partner to reach behind a pc, one at a time, and just keep plugging it in, unplugging it until you tell them to stop. Just because your old Wi-Fi router has been replaced by a newer model doesn’t mean it needs to gather dust in the closet. Also the footprint is a lot smaller as well. There are several aspect that differentiate hubs and switches, them from the aspect from speed, performance, research and others. I recently had an issue where i replaced a companies backbone 24 port hub with a 24 port switch 10/100, and the downstream hub could no longer connect. In addition to the possibility of having crossover cables in use, it's also entirely possible that there is a speed conflict. What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN? What Is Hub? The number of ports that can connect to the device is significantly more abundant in switch while it is less in a hub. I have 14 comp on this network and on the HUB they all work fine. • I think its also the crossover cables, if your switch doesn't have auto-mdx on all the ports, but also see if you have any downstream hubs. You connect devices to a hub using Ethernet cable and any signal sent from a device to the hub is simply repeated out on all other ports connected to the hub. Switches break the network into multiple collision domains and hence simplify the expansion rules by avoiding the collision domain restrictions. If they are I would imagine that you are actually seeing packet crashes and this is causing the unmanaged switch to stop working. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. A hub is an obsolete device that you would never want to buy these days. E. A switch decreases the number of collision domains.

Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Just the opposite, a switch imparts some latency between when it receives bits until it transmits them. It is newer in comparison with the hub, and it more common in the modern offices. Hubs and switches have two types of ports: medium dependent interface (MDI)and medium dependent interface crossed (MDI-X). Thank you so much! In the context of a network, a switch is a computer networking device that connects network segments. These are used to extend the maximum distance between nodes. In the picture above, the switch ties a file server, a high-powered PC, a print server, and a hub together for maximum bandwidth. He held a switch and a hub and they looked very similar. I recently had an issue where i replaced a companies backbone 24 port hub with a 24 port switch 10/100, and the downstream hub could no longer connect. A hub in networking allows users to connect more than one PC to a singular network. But in practise I would be looking at testing all the cables to make sure that they are all OK and working properly. © 2021 ZDNET, A RED VENTURES COMPANY. This maximizes security and efficiency of the network. One case is if you need to capture traffic to a host but the host can't run a capture utility itself and the switch it connects to also can't do a capture or span port. Hub and Switch. Each hub that is connected to another hub increases the size of the collision domain. From start to finish: How to host multiple websites on Linux with Apache, Understanding Bash: A guide for Linux administrators, We have 12 assorted cables (CAT3, CAT4, and CAT5) going to an. You then go to the hub and look for the light that is going on and off. Active Hub:- These are the hubs which have their own power supply and can clean, boost, and relay the signal along with the network.It serves both as a repeater as well as wiring centre. A hub generally has 4 to 12 ports. Wifi Constantly Disconnects, Will Mesh Network Help. Now, let’s get more concrete. i.e. The lights on the new hub have been revised and tell me that there are some cables running at 10MB and some at 100MB, and yes there are a few collisions.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. This avoids most collisions and as they came down in price they replaced HUBs in most places. John, the IT Infrastructure Support In-charge in our company, was connecting computers to a LAN. In general, no, there's no reason to use a hub over a switch, but they do still have a purpose in some special cases. All routers have a WAN (wide area network) port that can be attached to an external modem for Internet connectivity. ANS: T PTS: 1 16. As for the effort to install a switch, it’s minimal. ROUTER: Routes maintain lists of networks and tend to separate switches or hubs from each other. A switch operates at a lower, more efficient layer of the OSI model. If you have a downstream hub check that possibility, if not, im an idiot. If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. I think both of you are right. A networking switch is like smart network hub. The hub, in most applications, has been replaced with the switch. Most switches are transparent, which means they learn by themselves. • If the cables are not able to handle the signal, the switch will not establish the connection.What is the distance to the next device? Reply I would also document it as you go along so that the next time that a problem arises some poor fool doesn't need to spend days fault finding.Col. A hub may be based on Firewire, Ethernet, or a USB connection.On the other hand, a switch forms the control unit responsible for keeping the flow of electricity. I was wondering how a hub and a switc… LAN (Local Area Network) is a term used for a group of computers connected to a server in a distinct geographic location, like office etc.To distribute a LAN within a group of end-user devices, we need devices like Hub, Switch and Routers. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Some contain a LAN port that can be used to connect a switch or hub to the router and create a local area network, as the router itself may not contain its own PC ports. Two-thirds of the cables go into the ceiling. Passive Hub :- These are the hubs which collect wiring from nodes and power supply from active hub. As the Ximplies, an MDI-X port’s wiring iscrossed; this is because the transmit wire from the connected device must bewired to the receive line on the other. The lights also say that less than 10% of the bandwidth is being used. I guess I may need to plug each cable into a laptop and use ipconfig to get its ip address? ALL RIGHTS RESERVED. Hubs may be based on Ethernet, Firewire, or USB connections. A hub can have a single collision domain whereas in switch different ports have different collision domain. The switch can support different common network types like 802.11, Ethernet, Fibre and more. Are the devices attached to those cables capable of the speeds offered on the switch ports? IF DHCP, try to go static.My guess is it is the old cables causing your problems though. Hi all Back again with an update to the HUB/Switch swap.
