This article describes how to enhance the security of a Cisco router by using a Nipper. So how should we use it? The following article gives you a detailed answer. How do I use a Nipper? Since Nipper supports so many devices and is also known to support a wide range of multi-functional options, it is impossible for me to present them in all aspects. However, we c

not encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA.8. We recommend that you use FTP instead of TFTP for iOS upgrade and backup and configuration file backup. For example:Router (config) # ip ftp Username blushinRouter (config) # ip ftp password 4tppa55w0rdRouter # copy startup-config ftp:9. Upgrade

This article describes how to control the BT traffic of a Cisco router through specific operations, and describes the specific operation methods in detail. I hope this article will help you. Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple net

router. PDLM is written by the Packet Description Language Module, which means the data Packet Description Language Module. It is a description of the protocol layer of high-level network applications, such as the protocol type and service port number. Its advantage is to adapt NBAR to many existing network applications, such as http url, DNS, FTP, and VoIP. At the same time, it can also be defined, to enable NBAR to support many emerging network app
