cisco medium business router

A Cisco router is a commonly used routing product in large and medium-sized networks. As a core router, It is the soul of the entire network. If the Administrator is improperly set, the security deployment may be taken over by attackers if it is not in place. In that case, all the networks under it will fall, and the e

Network security is a required course for small and medium-sized enterprise network management. The author has collected the experiences of Qno xianuo in supporting enterprise users across China for your reference. First of all, let's talk about the basic configuration, that is, how to configure the WAN and LAN of the router. The main purpose is to enable the users of small and

Currently, Cisco access routers are widely used, and the features of media verification and encryption are one of the features of Cisco access routers. So I studied how to use the secure RTP media verification and encryption features, I would like to share it with you here and hope it will be useful to you. The media authentication and encryption features provided by the

from the Cisco2600 series, Cisco has adopted modular interfaces, some interface interfaces and network modules) the customer will purchase the product based on their own needs, which makes Cisco router products highly scalable. Cisco's Cisco2600 series routers have enterprise-level versatility, integration, and scalability. With the emergence of new enterprise a

With the development of China's routing industry, its application is also more extensive, especially the application of routers and firewalls. Here we mainly explain the security configuration of NetEye firewall and Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that Cisco routers already exist in the ne

departments, facilitating unified management. Use the IP/MAC binding function to avoid network management difficulties caused by IP address abuse in internal networks. You can also use QoS settings to manage the bandwidth for Intranet users to access the Internet, ensure that enterprise leaders want to ensure smooth connection to the Internet, ensure that the company's important business information is not delayed, and that important application serv

I found some posts about Cisco nav-10 WF configuration port forwarding sent by China Telecom Business pilot online, but it seems that one post said that later China Telecom gave him a newProgram, The Flash is normal. Later, he did not post the program. I found some information about business pilot. If you need to study it in depth, you can go and see:

for Cisco's enterprise-class routers and switch products, regular debugging, familiar with the operation of the product principles and business processes. This will be easy to deal with when you encounter the Internet and data failure. The following small series to you recommend the router debugging simple steps: 1. Use the Cisco
