I. BackgroundCustomers need to use, the demand is so simple. Say it briefly. There are too many network devices, the traditional manual backup network device configuration information workload is more and more large, and difficult to manage. There has to be a simpler way of doing this.Second, backup modeOne, Cisco device comes with kron command +tftp/ftp/httpThis

1. Troubleshooting)Here we will introduce the hardware and software problems that may occur when using vrouters. During the networking process, such as X.25, FR, DDN, DDR, TCP/IP, problems encountered in different network environments such as interconnection with IBM large hosts and solutions .? Troubleshooting tool? What is the Troubleshooting of TCP/IP connection? What is the problem with the serial port connection? What is the Troubleshooting of th

Background: 1. The relationship between the IP address and the MAC address in the ARP table of the layer-3 device. 2. the forwarding bridge table of the L2 device stores the correspondence between MAC and forwarding ports. 3. CDP (Cisco Discovery Protocol) is the link layer protocol for discovering adjacent devices between Cisco devices. 4. The forwarding table in the layer-2 module of a layer-3 swi

Cisco held a network lecture entitled "define your router with 256 or fewer bytes". The subject of this lecture is: "the accuracy and performance improvement of network security products forces hackers to successfully launch attacks in the first 256 bytes of the Code, so that they can easily intrude into the network wi

Hot Backup Routing protocol Hsrp:cisco Private protocolEnsures that when the network edge device or access link fails, the user communication can be quickly and transparently restored to provide redundancy for the IP network, by using the consent virtual IP address and virtual MAC address, two or more routers on the LAN segment can be used as a virtual router for external services.HSRP enables

After three years of work in the network field, I personally think that learning Cisco network is basically equivalent to mastering the network. It is determined that ccna, ccnp, and CCIE (routing and switching) are adopted starting from routing and switching ). First, let's move these three mountains over and look at

Experiment Name: Cisco router network address translation (NAT)Experimental purpose: To achieve all intranet IP to use a small number of public IP network connection to the InternetExperiment Introduction:With the help of NAT technology, when the intranet private address sends packets to the router, the private address is converted to a legitimate public IP addre
