托管与非托管交换机的区别(中英文)
当在同一位置连接多个以太网设备时,以太网交换机是最佳选择。它可能看起来很简单,就像插入插座板一样,但用户必须考虑一些重要的因素才能确保网络状态稳定。除了价格之外,托管和非托管交换机之间还有什么区别?
When connecting more than one Ethernet device in the same location, an Ethernet Switch is the way to go. It may seem simple, like plugging into an outlet strip, but there are significant considerations one must take to ensure your network is rock solid. What is the difference between managed and unmanaged switches besides price?
■托管型和非托管型交换机的区别
/The Difference Between Managed and Unmanaged Switches
首先是非托管以太网交换机,简单,易于使用,连接以太网设备就可以进行通信。这确实是以太网非管理型交换机的工作方式。它应该可以正常工作……但如果没有呢?非管理型交换机不提供任何类型的监控、警报或警报。它们只是接收数据并将其发回。使用非管理型交换机很像驾驶没有仪表板的汽车,可能会到达目的地,但还剩多少汽油,发动机是否过热,要走多快......?在有几个以太网设备和一到三个交换机的简单应用中,非管理型交换机通常是最佳选择,也是最经济的。一般是,如果拥有 3 个以上的以太网交换机,则应考虑管理型交换机。
Let's first consider Unmanaged Ethernet Switches, simple, easy to use, connect your ethernet devices and magically everything communicates. This is indeed how an Ethernet Unmanaged Switch is supposed to operate. It should just work... but what if it doesn't? Unmanaged switches do not provide any sort of monitoring, alerts or alarms. They just take data in and send it back out. Using an unmanaged switch is much like driving a car without a dashboard. You will probably get to your destination, but how much gas do you have left, is your engine overheating, how fast are you going...? In simple applications where there are a few ethernet devices and one to three switches TOTAL, unmanaged switches are often the best choice and will be the most economical. A general rule is if you have more than 3 Ethernet switches, you should consider Managed switches.
托管型交换机在网络中提供了很多价值。首先,可以了解网络状态。如果存在不正确的情况,托管型交换机会发送消息告知。这包括诸如带宽消耗高、有人刚刚插入端口甚至电源故障之类的事情。此外,托管型交换机可以实现冗余,如果以太网电缆被切断、拔下或插入错误的端口,或者即使交换机本身断电,这也可能是至关重要的。托管交换机足够智能,可以找到到达目的地的另一条路径,甚至可以阻止不应在特定端口上发生的通信,从而防止出现严重的网络问题。
Managed switches provide a lot of value in a network. First, they can let you know the status of the network. If there is a condition that isn't right, a managed switch can send you a message telling you so. This includes things like bandwidth consumption is high, someone just plugged into a port and even power supply failure. Additionally, a Managed switch can implement redundancy. This can be critical if an Ethernet cable gets cut, unplugged, or plugged into the wrong port or even if the switch itself powers down. Managed switches are intelligent enough to find another path to the destination, or even block communications that should not be occurring on a specific port preventing serious network issues.
■实际应用 / Real-World Applications
一些托管型交换机具有具有实际价值的额外功能。一个例子是PoE(以太网供电)监控。如果正在使用 PoE 相机或其他 PoE 设备,托管型交换机可以监控它们以确保它们正常工作,如果没有,托管型交换机可以自动重置该端口的电源并重新启动设备,从而节省服务呼叫。
Some Managed switches have extra features that have real-world value. One example is PoE (Power over Ethernet) monitoring. If you are using PoE Cameras or other PoE devices, a Managed switch can monitor them to ensure they're functioning, and if not, a managed switch can automatically reset the power on that port and reboot the device, thus saving a service call.
