the devices connected to the internet have a ground wire. These devices include hosts, workstations, hubs, switches, routers, and MODEM connected To routers. The terminal or PC that configures the router must also use a valid power supply. CISCO synchronous serial interfaces are commonly used. Different interfaces, such as RS232 and V.35, can be obtained through different cables. In addition, the cables of

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

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery

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 can make a basic demonstration. In our example

1. Use the ip verfy unicast reverse-path network interface command This function checks each packet passing through the router. In the router's CEFCisco Express Forwarding) table, if the route entry of the packet to the network interface does not have the source IP address of the packet, the router discards the packet. For example, if the
