A router is a commonly used network device. How should we configure VOIP implementation? What are the specific operation steps? The following article will give you a detailed introduction. Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco

It took a few days to write this blog, and the commands for configuring Cisco routers are more clearly written in the tutorials, but many commands remember that they may not be able to be used in the actual network of the enterprise, and I am here to introduce how to log in to the Cisco router using terminal equipment, How to access the configuration network, how

For common users, it is necessary to learn how to back up the Cisco router configuration file to ensure the security of our routers. In recent years, many cities have established urban financial networks. The construction of these networks has promoted the construction of electronic finance in various regions. Vro is a key device of the city financial network and a bridge to the computer network. It can not

Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technology that transmits voice over the Internet. It has grown with the development of Internet technology

In the Cisco router product, we usually need to use restricted access for general users when we initially configure. This is very important for routers, by default, our router is an open system, access control options are turned off, any user can log on to the device for further attack, so we need our network administrator to configure the password to restrict un

Currently, Cisco routers have become a leader in the routing industry. Many people may not understand the configuration steps of Cisco routers. It does not matter.

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

Cisco router security-TCP connections are common attacks on the network. In fact, most attacks are based on TCP connections, and a large amount of request data is sent to cause Server Denial of Service, is a connection attack. Next, I will take a Cisco router as an example to introduce how to intercept illegal TCP conn

There are a lot of users using Cisco routers, So I studied the global debugging of Cisco routers and shared it with you here. I hope it will be useful to you.
