What is Cisco Packet tracer?The Cisco Packet Tracer is a powerful network simulation tool for training in Cisco certifications. It gives us a good view of the interfaces of each router and network device, with many options, and we can use unlimited devices in the network just like with physical machines. We can create multiple networks in a single project for spe
There are a lot of users using Cisco routers, global debugging of Cisco routers here today I would like to introduce you, I hope to be useful to you.
The boundaries of global and interface commands are obvious when conducting Cisco router configuration. In this case, we use the global to identify the commands that cannot be used for interface debugging or for sp
Cisco's NAC Framework is an architecture designed to help multiple hardware and software components work together to protect your network from adverse client attacks. This article mainly introduces the NAC Framework architecture.
What is a Cisco NAC Framework component?
Cisco's NAC Framework tries to solve a complicated problem, so it must be a complicated solution. Fully implementing the NAC Framework is not a simple task, because the entire architec
The Cisco simulator runs in a Windows environment and consumes resources. Therefore, Dynamips is installed on an existing CentOS6Linux operating system to simulate Cisco routing and switching. 1. Download: download the required packages [root @ ciscotest] # wgethttp: // www. ipflow. utc. fr...

If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail.
As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has
Compared with Cisco, you should pay attention to setting up a Huawei switch so that you can easily avoid common problems and enjoy a smooth sailing when setting up a Huawei switch. How to Set Up A Huawei switch has become a concern. This article explains in depth the principles, ideas, and test process of the switch.
Compared with Cisco devices. The comparison between the two is actually a comparison betwee
As a leader in the current routing market, Cisco routers have advanced routing technology. Here we mainly analyze the future development of Cisco routers. Cisco routers are the leading enterprises in the routing industry, its market competitiveness is very strong, and Cisco also brings new opportunities to partners. Re
There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology.
Generally, a router is a bridge between a LAN and a wan.
The so-called router's own backup technology is designed to solve a router's own hardware (such as memory, CPU) or software IOS fault or local port fault, network breakdown caused by the failure of the port or line of the connected local area device.

Cisco Fabric Manager is a Web-based, easy-to-use, responsive application that can be used to manage switches and networks in an integrated manner, thus simplifying the storage lan san) management of Cisco MDS 9000 series switches. Cisco Fabric Manager provides network-level management functions for storage administrators, including identification, multi-Switch co
The following describes how to use a Cisco switch and how to operate it. When we debug a switch, the switch displays the details of each port in sequence, this includes port disconnections and explains the accumulated information.
Cisco is the main force in the entire vswitch. Its products are doing very well in the market. The following article will detail some of the usage skills and precautions of
This is an article about the Cisco router IP address, which is very old and should be useful to everyone, so we have selected it from the vast network. Hope you don't sink it down. We will give you a satisfactory response on how to use the IP address of the Cisco router to obtain traffic. When using a cisco router as an Internet Router, cisco's IP packet filterin
This article is intended for CISCO router users. It mainly introduces technical issues related to basic network equipment, regular system upgrades, and use of CISCO routers. I hope this article will help you.
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 in the Network: vswitc
Abstract: This article describes the first time that the author personally contacts the Cisco PIX Firewall and summarizes ten basic configurations of the firewall.
A hardware firewall is a wall between networks to prevent illegal intrusion and filter information. In terms of structure, it is simply a PC-type computer host with Flash) and firewall operating systems. Its hardware is similar to the common control machine, which is suitable for 24 hours
