Second, the boot sequence of the routerWhen the router starts, it needs to perform a series of operations, the so-called Boot sequence (boot sequence), which is designed to testHardware and load the required software. The boot sequence includes the following steps.(1) The router performs post (POST) 0 post will check the hardware to verify that all compone

During running, RAM contains route table items, ARP buffer items, log items, and groups waiting for sending in queue. In addition, it also includes Running configuration files (Running-config), Code being executed, IOS operating system programs, and some temporary data information. The reading method o

This article describes how to quickly install and maintain a vro from the aspects of control port interface connection, initialization and installation, and troubleshooting and detection of common routing faults. See the detailed description below. A terminal or PC configured with a Cisco router must also use a valid power supply. Cisco synchronous serial interfa

The Cisco Router performs very well in the market. Here we will mainly focus on Cisco routers and explain in detail the detailed steps of Cisco router configuration. Cisco routers are the core devices for network communication, cu

Network is inseparable from the password, as a network administrator to remember more than one router password, if the router password forgotten, we need to set up a router to restore the password. Router password recovery has a common, that is, let the router start to skip

network segments can be routed for communication. Firewalls are produced by people's security requirements. Whether data packets can be correctly arrived, the arrival time, and the direction are not the focus of the firewall. The focus is on this series.) whether data packets should pass through and whether they will cause harm to the network. 2. Different fundamental purposes　 The fundamental goal of a vro is to keep the network and data accessible

There are a lot of users using Cisco routers, So I studied the global debugging of Cisco routers and shared it with you here. I hope it will be useful to you. 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

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

Time Protocol (NTP), a protocol designed to synchronize the clocks of computers over a network, for policyears. NTP Version 3 is a standard protocol ormalized in RFC 1305 protocol hat uses the user datateprotocol (UDP) and Port 123. Unlike PCs or servers, Cisco network devices specifically need to run NTP to synchronize the time and date. That's because most Cisco devices don't have an internal clock. For

This article describes in detail how to set the default settings for Cisco routers in terms of security analysis, specific measures, and default settings. I believe this article will help you. Security Analysis Readers who have experience configuring routers should know that network administrators often set access control lists on routers or switches to prevent viruses and hackers. By default, the "deny any" statement is added to the access control li
