We&#8217;ll also cover a question that trips up a lot of buyers: when a switch alone doesn&#8217;t cut it, and you need a router as well.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By the end, you should be able to look at your own network and know roughly what you&#8217;re shopping for.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_a_Switch_Does_and_How_It_Differs_From_a_Router\"><\/span><b>What a Switch Does (and How It Differs From a Router)<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A switch is a device within the same LAN (local network) that allows devices (computers, printers, servers, access points, etc.) to communicate directly with one another. It reads the destination address of each piece of data and forwards it straight to the correct device.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A router does a different job. It links one network to another, typically from your local network to the internet. This is the heart of the <\/span><b>switch vs router difference<\/b><span style=\"font-weight: 400;\">: A switch works inside your building to direct traffic; a router works outside your building, directing traffic to your WAN connection or between different buildings.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most small networks will require both, not either\/or. Your switch is sending traffic out from all desks, printers, and access points within the office. Your router then sends anything that&#8217;s meant for the rest of the internet or another site out over your WAN link. We&#8217;ll come back to this later, because there are situations \u2014 particularly for branch offices \u2014 where a router does something a switch simply can&#8217;t.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Key_Factors_to_Consider_Before_Buying\"><\/span><b>Key Factors to Consider Before Buying<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Before you look at a single model number, it helps to answer a few questions about your own setup.

A five-person office and a fifty-desk floor plan will land on very different specs, even if both just want &#8220;a good <\/span><b>gigabit switch<\/b><span style=\"font-weight: 400;\">.&#8221; Treat this list as your shopping brief before you start comparing products.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Managed_vs_Unmanaged_vs_Smart_Switches\"><\/span><b>Managed vs Unmanaged vs Smart Switches<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><b>Managed vs unmanaged switc<\/b><span style=\"font-weight: 400;\">h models are based on control: a managed switch can be configured, monitored, and segmented; an unmanaged switch connects devices for which no settings are to be touched.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The easiest type of switch is an unmanaged switch. It&#8217;s plug-and-play \u2014 no login screen, no configuration, and no ongoing admin. For many small configurations, that&#8217;s the correct answer: a small back office with six desks and a shared printer doesn&#8217;t need a management interface it will never open.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At the other end is a managed switch. You can use VLANs to isolate departments or traffic types, and separately use the switch&#8217;s other managed features to monitor port-level usage, set up link aggregation, and control which devices are allowed to connect.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That&#8217;s when <\/span><b>VLAN configuration<\/b><span style=\"font-weight: 400;\"> can get you the job done, which you might need when you want to keep, say, the data traffic for your guest WiFi separate from the data traffic for your finance team on the same physical switch.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In between is the<\/span><b> smart switch vs. managed switch<\/b><span style=\"font-weight: 400;\"> category, often referred to as &#8220;web-managed. Smart switches, which typically have a more limited feature set, provide a simplified web interface to some of the more commonly managed features \u2014 basic VLANs, monitoring, and port settings \u2014 but do not have the depth or complexity of an enterprise-grade managed switch.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For the real world, the <\/span><b>NetGear GS748T <\/b><span style=\"font-weight: 400;\">is a good example. It&#8217;s a component of NetGear&#8217;s smart\/web-managed range, offering buyers VLAN support and a dashboard that&#8217;s managed by a browser, with none of the enterprise switch operating system learning curve. A smart switch, such as this, is a no-brainer when an SMB wants to do something a bit more with some control \u2014 such as separating VLANs and watching the port activity \u2014 but doesn&#8217;t have a network engineer available.

VLANs are difficult to add after your network has grown to a point that it&#8217;s outgrown the capabilities of an unmanaged switch.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Many_Ports_Do_You_Need\"><\/span><b>How Many Ports Do You Need?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The trick to getting the port count right is to count all the wired devices you have today, then give yourself some realistic growth margin, and then round up, not down, because it&#8217;s much more likely that you will run out of ports than buy a few too many.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is where the old <\/span><b>24-port vs. 48-port switch<\/b><span style=\"font-weight: 400;\"> dilemma enters, and it&#8217;s better to go over the numbers than guess them.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The<\/span><b> Cisco Catalyst WS-C3750G-24TS-S<\/b><span style=\"font-weight: 400;\"> is a 24-port managed switch that is ideal for a single-floor office, a medium-sized server room, or a department that is not planning on expanding and scaling rapidly in the near future. 24 ports cover a reasonable number of desks, a handful of access points, and a few printers or shared devices, with some capacity to spare. The <\/span><a href=\"https:\/\/bulkdevices.co.uk\/ws-c3750g-24ts-s-cisco-catalyst-3750g-24t-s-24-ports-24-x-10-100-1000-managed-1u-rack-mountable-gigabit-ethernet-switch\"><span style=\"font-weight: 400;\">Cisco Catalyst WS-C3750G-24TS-S 24-port switch<\/span><\/a><span style=\"font-weight: 400;\"> is available on our site.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><b>NetGear GS748T<\/b><span style=\"font-weight: 400;\">, on the other hand, has 48 ports\u2014double the density in about the same space. That&#8217;s a better solution for a larger open-plan office, one with several departments using it, or any business with known growth in headcount (and device counts) over the next couple of years.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Neither is inherently better \u2014 they&#8217;re built for different scales of network. Buy too few ports, and you&#8217;ll be shopping for a second switch sooner than planned; buy far more than you need, and you&#8217;re paying for capacity that sits idle. In a 10-desk office, a 48-port switch is just &#8220;overkill&#8221; in terms of rack space and cost.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you need to expand your network of a single switch anytime soon, you should consider a <\/span><b>stackable switch<\/b><span style=\"font-weight: 400;\"> approach, too: Several switches can be connected together and controlled as one logical switch, whereas a single gigantic one can be purchased now with the hope that it will last until you need it to.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The rule of thumb is to add 20-30% to the number of wired devices you currently have, and choose the port count that fits within that amount.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Layer_2_vs_Layer_3_Switching_Explained\"><\/span><b>Layer 2 vs Layer 3 Switching Explained<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The difference between 2- and 3-layer switching is that the 3-layer switch can route traffic between different networks, whereas the 2-layer switch can only route traffic within an individual network.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8211; A Layer 2 switch forwards traffic based on MAC addresses only, which is adequate for most simple office networks where all traffic is on one VLAN, or for some networks where inter-VLAN routing is performed on some other device, e.g., a firewall.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8211; A Layer 3 switch integrates IP-based routing directly into the switch. It will matter when you start to create multiple VLANs, and you need to route traffic between them, such as a workstation on the &#8220;Office&#8221; VLAN wanting to print to a device on the &#8220;Printers&#8221; VLAN, since routing has to be performed by another device if it&#8217;s a pure Layer 2 switch.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To summarize: If you have one flat VLAN, or you already have VLAN routing performed on another router or firewall, then Layer 2 will suffice. If you wish to have inter-VLAN routing done by the switch itself and not require adding another box to the rack, then check for Layer 3 functionality. This choice typically doesn&#8217;t matter until your network is complex enough to have more than one VLAN in the first place.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"PoE_%E2%80%94_Do_You_Need_It\"><\/span><b>PoE \u2014 Do You Need It?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Power over Ethernet (PoE) matters if any device on your network draws its power through the same cable that carries its data, instead of needing a separate power socket.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The most common PoE devices in an office are IP phones, wireless access points, and network cameras. Instead of running a power cable to each ceiling-mounted access point or desk phone, PoE lets a single Ethernet cable do both jobs. That&#8217;s a real saving in cabling cost and installation time, particularly for access points mounted somewhere without a nearby power outlet.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If none of your devices need it, there&#8217;s little reason to pay extra for a PoE-capable switch \u2014 it&#8217;s an added cost for a feature you won&#8217;t use. If you do have PoE devices, or plan to add some (extra access points as you expand Wi-Fi coverage, for instance), check the switch&#8217;s total PoE power budget rather than just the port count. A switch can technically have PoE on every port but not enough total wattage to power them all at once \u2014 this is worth confirming against your specific device list before buying.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Uplink_Expansion_Ports_SFP\"><\/span><b>Uplink &amp; Expansion Ports (SFP)<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><b>SFP<\/b><span style=\"font-weight: 400;\"> stands for Small Form-factor Pluggable \u2014 a slot that accepts interchangeable fibre transceiver modules, most commonly used to connect one switch to another, or a switch to a firewall, using a fibre connection instead of standard copper cabling.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The <\/span><b>SFP uplink ports<\/b><span style=\"font-weight: 400;\"> are important in two situations: first, when the distance requirements of copper cabling are a concern when connecting switches within a building, and second, when a fast, dedicated link is required between the core switch and other network equipment without having to share bandwidth on the same ports.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Fibre uplinks via SFP also future-proof a purchase somewhat \u2014 even if you don&#8217;t need fibre connectivity today, having the option there means you&#8217;re not locked out of it later without buying a new switch. If you&#8217;re planning to connect multiple switches as your network grows, checking SFP availability before you buy is worth the extra few minutes. You can<\/span><a href=\"https:\/\/bulkdevices.co.uk\/networking-devices\/switches\/network-switches\"> <span style=\"font-weight: 400;\">browse our full range of network switches<\/span><\/a><span style=\"font-weight: 400;\"> to compare SFP options across models.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_a_Switch_Alone_Isnt_Enough_Adding_a_Router\"><\/span><b>When a Switch Alone Isn&#8217;t Enough: Adding a Router<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A switch controls traffic within the LAN; it does not know anything about the Internet or a second physical location \u2014 and there are common scenarios where a business requires a router to operate in tandem with its LAN switch instead of in place of it.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The clearest example is branch office connectivity. For a small remote site, whether it is a satellite office, a shop, or a temporary site, you often find that you have a WAN connection that cannot be totally based upon a fixed-line internet connection; either because a fixed line isn&#8217;t available, or because you want a backup if one drops. That&#8217;s where a router such as the <\/span><b>Cisco C887VAG-4G-GA-K9 4G LTE <\/b><span style=\"font-weight: 400;\">router can help: It keeps a site online over the mobile network if the primary WAN link fails, or it can serve as the primary connection where laying a fixed line isn&#8217;t practical.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Again, it is important to understand that this device is not a switch, nor is it a replacement for a switch. There still needs to be a switch at the site to tie its desks, printers, and access points together at the site level. The role of the router is only on the WAN side, to get that local network&#8217;s traffic out to the internet or back to head office, and the 4G is either on the main path or the failover path.
