Some time ago, my colleague asked me a question about the DHCP configuration of the Cisco router. At that time, I did not give a positive answer, because this was my first time. In the following days, I have consulted relevant materials and are satisfied with the following answers. Share it with you now! In addition, most people do not know about the computer and do not operate these operations. Therefore, the customer asked us to allow any computer t
In the network industry, Cisco System Inc. is unknown. With its IOS (Internet Operating System), Cisco is an absolute leader in the multi-protocol router market. Currently, nearly 80% of routers on the Internet come from Cisco. In fact, Cisco also has a full range of network devices, including hubs, switches, access se
There are many users of Cisco routers. Here we mainly introduce how to keep Cisco routers away from DoS attacks. DoS Dictionary Attacks against routers allow attackers to gain access to Cisco routers or prevent users from using the routers. In this article, you can find out how to use the enhanced login function of the Cisco
With the development of China's routing industry, its market demand is also increasing. As a leader in the routing industry, Cisco routers have a very high market share. Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk.
