Cisco routers are widely used in network interconnection. Among them, 2500 series routers are widely used in low-end users. So what if you accidentally forget the superuser password of the 2500 series router? Don't be afraid, as long as you can restore as follows:Preparation: a computer running Terminal simulation program can start a Super Terminal in Windows 95/98), and the microcomputer serial port COM1/C

The Cisco router NAC solves the problem. The so-called NAC is an architecture that allows multiple hardware and software components to work together to protect the user's network from adverse client attacks. 1. It is not easy to fully implement NAC, because the entire architecture contains too many different components from other vendors. For example, the architecture contains the NAC Policy Manager and mul

After decades of development, from the first four-node ARPANET to the ubiquitous Internet, computer networks have penetrated into our lives. With the explosive growth of the computer network scale, as a router to connect devices also become more important. When a company builds a network, how to reasonably configure and manage the router becomes one of the important tasks of the Network Manager. This topic

A Cisco router is detected infected with a secret backdoor. Security company FireEye researchers reported that backdoor programs called SYNful knock were found on 14 Cisco routers in 4 countries. Cisco has confirmed this. The attack does not take advantage of the vulnerability of the product itself, but requires valid

. RPF reverse transmission path forwarding) is an input function activated on a network interface or sub-interface to process packets received by the router. It is very important to enable the CEF function on the vro, because RPF must rely on CEF. Unicast RPF is included in Cisco IOS 12.0 and later versions that support CEF, but does not support Cisco IOS 11.2 or
