When we think of connectivity in a network, the router is probably the first device that comes to mind, but switches play a vital role in enabling network devices to communicate. You also want to check the physical state of the device and verify that none of the cables are damaged. If for any reason putty is not an option for your setup, you can get similar results with a PuTTY alternative. To start configuration, you want to connect the switch console to PuTTY. You can do this by doing the following:.
You can make the switch easier to locate in the network by assigning a hostname. Enter the following command to assign a hostname:. To assign an administrator password to enter the following command:. The next step is to configure passwords for Telnet and console access.
Configuring passwords for these is important because it makes your switch more secure. If someone without authorization gains telnet access then it puts your network at serious risk. You can configure passwords by entering the following lines See the top paragraph for Telnet and the bottom paragraph for Console access. ACLs ensure that only the administrator can connect to the router through Telnet. Next, you need to configure a network management IP address.
You can do this by entering the following command:. At this stage, you want to assign a default gateway to the switch. The default gateway is essentially the address of the router that the switch will be communicating with. To assign the default gateway, enter the command below change the IP address to that of your router. As a best practice, it is a good idea to disable any unused open ports on the switch.
Cyber-criminals often use unsecured ports as a way to breach a network. Closing these ports down reduces the number of entry points into your network and makes your switch more secure. Saving the configuration will make sure that your settings are the same when you open up your next session.
To save enter the following command:. It is also a good idea to use a network traffic analyzer to monitor network traffic. As a Cisco device, your switch will have the communication protocol NetFlow. However, it must be configured first. You can configure NetFlow by completing the four steps below. Before we begin, enter Global Configuration Mode by executing the following command:.
Completing simple tasks like configuring passwords and creating network access lists controls who can access the switch can enable you to stay secure online.
Incomplete or incorrect configurations are a vulnerability that attackers can exploit. Configuring a Cisco switch is only half the battle, you also have to regularly monitor its status. Any performance issues with your switch can have a substantial impact on your users. Using a network monitoring tool and network analyzer can help you to monitor switches remotely and review performance concerns. Taking the time out of your day to configure a switch and assign strong passwords gives you peace of mind so that you can communicate safely online.

Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. This is a very efficient means of data transmission, instead of broadcasting it on all ports.

This tutorial explains basic switch configuration commands in detail with examples. Configuration and commands explained in this tutorial are essential commands to manage a Cisco switch effectively. Learn how to configure and manage a Cisco Switch step by step with this basic switch commands and configuration guide. To explain basic switch configuration commands, I will use packet tracer network simulator software. You can use any network simulator software or can use a real Cisco switch to follow this guide. There is no difference in output as long as your selected software contains the commands explained in this tutorial. Create a practice lab as shown in following figure or download this pre-created practice lab and load in packet tracer.
У нас есть время, но только если мы поспешим, - сказал Джабба. - Отключение вручную займет минут тридцать. Фонтейн по-прежнему смотрел на ВР, перебирая в уме остающиеся возможности. - Директор! - взорвался Джабба. - Когда эти стены рухнут, вся планета получит высший уровень допуска к нашим секретам.
И направился в сторону люка. - Коммандер. Хейл очень опасен. Он… Но Стратмор растворился в темноте.
У меня есть доказательство! - Сьюзан встала и подошла к терминалам. - Помнишь, как ты отключил Следопыта? - спросила она, подойдя к своему терминалу. - Я снова его запустила. Посмотрим, вернулся ли. Разумеется, на ее экране замигал значок, извещающий о возвращении Следопыта.
Сьюзан удалось протиснуть в щель плечо. Теперь ей стало удобнее толкать. Створки давили на плечо с неимоверной силой.
- Он засмеялся. - Супружеская пара без секретов - это очень скучно. Сьюзан застенчиво улыбнулась. - Если будет еще интереснее, чем этой ночью, я не смогу встать. Дэвид привлек ее к себе, не ощущая тяжести.
Сьюзан не понимала, к чему клонит Стратмор. - В марте я испробовала алгоритм с сегментированным ключом в миллион бит.
