The Cisco Router performs very well in the market. Here we will mainly focus on Cisco routers and explain in detail the detailed steps of Cisco router configuration. Cisco routers are the core devices for network communication, currently, it has been widely used. I will introduce my experience in practice as follows. C

Figure Cisco Catalyst 3550 series smart Ethernet switches are a new type of enterprise-class stackable multi-layer switch that provides high availability, high scalability, and high security, and improves the management capabilities of network operations. With a series of Fast Ethernet and Gigabit Ethernet configurations, the Catalyst 3550 series can serve as a powerful access layer switch for medium-sized enterprise cabling rooms and backbone n

This article describes in detail how to understand the technology of Cisco routers in terms of basic network equipment issues, regular system upgrades, and the use of Cisco routers. I believe you will be helpful after reading it. These two tools enable communication between devices connected to the network and other networks. Although vrouters and vswitches look very similar, they have different functions i

Introduction of Cisco router command modes knowledge about Cisco router command modes is very helpful for network security management. network security management involves many aspects, but throughout many security events, we can draw a basic conclusion that the harm is caused by ignoring the basic security measures. This article will discuss the importance of maintaining the

Cisco's Internet Operating system (IOS) is a complex operating system optimized for interconnection-similar to a local-area operating system (NOS), such as Novell's NetWare, for LANs. iOS provides a uniform rule for a long period of time to maintain an Internet economy effectively. In short, it is a hardware-separated software architecture that can be dynamically upgraded to adapt to changing technologies (hardware and software) as network technology continues to evolve. iOS can be viewed as an

It is very important for Cisco router users to learn about commands for password recovery of Cisco routers. For many beginners, the ROM Monitor of Cisco routers is often unfamiliar or even daunting for a simple reason, first, we do not often use this mode and are not familiar with its related operations; second, Operation errors in ROM Monitor mode, it often caus

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. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The company is headquartered in Beijing and has three branches nationwide. It is required that data in four locations be queried i

In addition to address binding, ARP configurations of Cisco routers are getting more and more attention. Therefore, we will discuss two aspects here. It seems a bit messy, but I hope it will help you. I know that the command for binding the IP address of the cisco router to the mac address is arp IP address, mac address, arpa, but I think there should be a command that shows the start binding command. for e

Single-user Cisco ProductsSome products of the SOHO series use dial-up technology, such as ISDN Integrated Service data network, which allows users to roam from one place to another, or dial to the central site.The Cisco200 series for ISDN has gradually withdrawn from the market. We recommend that you upgrade it to the 700 series. The 600 series can be used with digital user line DSL) interfaces. The 800 Series features more than the 700 series, espec

There are many knowledge about Cisco routers. Here we mainly analyze the specific methods for Cisco router configuration. Have you ever encountered this problem in daily network management and maintenance: You have been forcibly rejected by a vro or vswitch, a former "friend", because you forgot your password, parameter resetting and information statistics are not allowed. The following describes how to cle

Subnet Mask hardware basic Ethernet protocol Network Management A router is a bridge of a computer network and a core device connecting to an IP network. It can connect different networks, select data transmission routes, and block unauthorized access. Router configuration is not easy for beginners. Take the Cisco router as an example to introduce the general knowledge and configuration of the router for your reference When configuring the ro

In the real world or laboratory environment, Cisco IOS test commands are very useful and powerful commands. Learn the basic usage of this command and learn a few useful sub-commands. This is not surprising if you have never used the Cisco IOS test command. I have met many network administrators who have never heard of this command. Based on my experience, this test is a very useful and powerful command in b

This article describes in detail how to improve OSPF security for Cisco routers. This article describes how to improve network security in terms of protocol analysis and router authentication solutions. OSPF is also an open version of The Link Status Protocol. In practice, OSPF is often used in some large and hybrid networks. In the previous article, I talked about the defects of the RIP Protocol. The reason why network experts develop the OSPF protoc

Hello everyone, the recent development of Huawei is very good, especially in the domestic to Cisco's strategy, many friends will ask me a question, I should go to learn Cisco or to learn Huawei?Let me take this opportunity to discuss with you.Just from the direction of the routing switch (Cisco is called Rs direction, Huawei called the digital direction), technically speaking, the difference is not very lar
