This ensures that the router writes the newly pushed configuration in memory. Network device configuration using template. With all the routers reachable and accessible through SSH, let us configure a base template that sends the Syslog to a Syslog server and additionally ensures that only information logs are sent to the Syslog server. Explanation: Networking devices operate in two planes: the data plane and the control plane. The control plane maintains Layer 2 and Layer 3 forwarding mechanisms using the CPU. The data plane forwards traffic flows. SDN virtualizes the control plane and moves it to a centralized network controller.
Few things are more important to your machine than a good network connection. Here are three ways to configure the interfaces needed to make this happen.
More Linux resources
Almost any useful work that one would want to do with a Linux system requires a network interface. Want to browse the web, watch YouTube, stream video, audio or files? It’s all done over the network interface. RPM-based Linux distributions using Gnome have several fundamental ways to configure the network interface. I'm describing three ways in this article. All of the configuration methods require the entry of sets of numbers that allow the network interface to operate.
You will need three fundamental pieces of numerical information in order to minimally configure a network interface to work over IPv4 and more if you want to define things like IPv6, hostnames, or DNS servers. This article covers the bare minimum for IPv4. Those three fundamental numerical pieces are:
IP Address: The unique number defining the access point to your network interface. It has the form: xxx.xxx.xxx.xxx, where “xxx” are three, or fewer, numbers between 0 and 255. It’s possible for this number to be purely made up, but normally it takes a form that works with the other three numbers. If you are using a home router with DHCP, which is the typical default configuration, the router will “assign” the IP address to your network interface. You won’t have to enter the number at all.
Gateway: The unique number assigned to the network interface at the 'other end of the wire' that your computer must communicate through. Again, it has the general xxx.xxx.xxx.xxx format and takes a form that also works with the other two numbers. If you are using a home router, your home router generates this number because it is the gateway through which you communicate with the wider world.
Netmask: The non-unique number that defines the network itself. This number can be automatically generated but is sometimes requested by the method you use to configure the interface. It, too, has the format xxx.xxx.xxx.xxx.
Note that I’m not going into the how of these numbers; I’m just telling you they are needed to configure the network interface. I’ll skip that so you can get on into the point of the article: Three ways to configure network interfaces. In each case, the numbers I use will be real numbers applicable to the system I used to write this article. I used CentOS 8 to generate the images, but everything you see here is the same in Fedora and Red Hat Enterprise Linux.
At installation time
The Anaconda installer prompts for network configuration and you can’t complete the installation without providing these numbers to the installer. Here’s the initial screen, using “Network & Host Name” in the rightmost column, third selection down:
Windows usually detects the presence of a network adapter automatically; typically, you don’t have to install device drivers manually for the adapter. When Windows detects a network adapter, Windows automatically creates a network connection and configures it to support basic networking protocols. You may need to change the configuration of a network connection manually, however.
The following steps show you how to configure your network adapter on a Windows 10 system:
1Click the Start icon (or press the Start button on the keyboard), and then tap or click Settings.
The Settings page appears.
2Click Network & Internet.
The Network & Internet page appears. Edgeview 2 842 n.
3Click Ethernet.
Aiseesoft mac video converter ultimate 9 0. The Ethernet settings page appears.
4Click Change Adapter Options.
The Network Connections page appears. This page lists each of your network adapters. Exposure x5 bundle 5 2 1 1974. In this case, only a single wired Ethernet adapter is shown. If the device has more than one adapter, additional adapters will appear on this page.
5Right-click the connection that you want to configure and then choose Properties from the contextual menu that appears.
This action opens the Ethernet Properties dialog box.
6To configure the network adapter card settings, click Configure.
The Properties dialog box for your network adapter appears. This dialog box has seven tabs that let you configure the adapter:
- General: Shows basic information about the adapter, such as the device type and status.
- Advanced: Lets you set a variety of device-specific parameters that affect the operation of the adapter.
- About: Displays information about the device’s patent protection.
- Driver: Displays information about the device driver that’s bound to the NIC and lets you update the driver to a newer version, roll back the driver to a previously working version, or uninstall the driver.
- Details: With this tab, you can inspect various properties of the adapter such as the date and version of the device driver. To view the setting of a particular property, select the property name from the drop-down list.
- Events: Lists recent events that have been logged for the device.
- Power Management: Lets you configure power management options for the device.
When you click OK to dismiss the dialog box, the network connection’s Properties dialog box closes and you’re returned to the Network Connections page. Right-click the network adapter and choose Properties again to continue the procedure.
7Review the list of connection items listed in the Properties dialog box.
- Client for Microsoft Networks: This item is required if you want to access a Microsoft Windows network. It should always be present.
- File and Printer Sharing for Microsoft Networks: This item allows your computer to share its files or printers with other computers on the network.This option is usually used with peer-to-peer networks, but you can use it even if your network has dedicated servers. If you don’t plan to share files or printers on the client computer, however, you should disable this item.
- Internet Protocol Version 4 (TCP/IPv4): This item enables the client computer to communicate by using the version 4 standard TCP/IP protocol.
- Internet Protocol Version 6 (TCP/IPv6): This item enables version 6 of the standard TCP/IP protocol. Typically, both IP4 and IP6 are enabled, even though most networks rely primarily on IP4.
8If a protocol that you need isn’t listed, click the Install button to add the needed protocol.
A dialog box appears, asking whether you want to add a network client, protocol, or service. Click Protocol and then click Add. A list of available protocols appears. Select the one you want to add; then click OK.
9To remove a network item that you don’t need (such as File and Printer Sharing for Microsoft Networks), select the item, and click the Uninstall button.
For security reasons, you should make it a point to remove any clients, protocols, or services that you don’t need.
10To configure TCP/IP settings, click Internet Protocol (TCP/IP); click Properties to display the TCP/IP Properties dialog box; adjust the settings; and then click OK.
The TCP/IP Properties dialog box lets you choose among these options:

- Obtain an IP Address Automatically: Choose this option if your network has a DHCP server that assigns IP addresses automatically. Choosing this option dramatically simplifies administering TCP/IP on your network.
- Use the Following IP Address: If your computer must have a specific IP address, choose this option and then type the computer’s IP address, subnet mask, and default gateway address.
- Obtain DNS Server Address Automatically: The DHCP server can also provide the address of the Domain Name System (DNS) server that the computer should use. Choose this option if your network has a DHCP server.
- Use the Following DNS Server Addresses: Choose this option if a DNS server isn’t available. Then type the IP addresses of the primary and secondary DNS servers.
