and a switch are connected with the console lineHow it works: Switch password recovery fundamentals: Change the Config.text file name in the switch to a different file name, and then enter the configuration mode to change the password, and finally restore the Config.text file nameSteps:1. Power off first2. Power off while holding down the mode key on the switch until the display light on the switch is no longer flashing (5~10s), then release3. At this point, enterSwitch:flash_init (Initialize F

CISCO PT Simulation Experiment (12) configuration of router static routesExperimental Purpose : Master the configuration method and application of static routeMastering Route descriptions in the routing tableFamiliar with the principle and process of Routing and Packet forwardingExperimental Background :In addition to the headquarters of a company, there is another branch, and there is a separate LAN, in o

For common users, it is necessary to learn how to back up the Cisco router configuration file to ensure the security of our routers. In recent years, many cities have established urban financial networks. The construction of these networks has promoted the construction of electronic finance in various regions. Vro is a key device of the city financial network and a bridge to the computer network. It can not

Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technology that transmits voice over the Internet. It has grown with the development of Internet technology

Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing t

Cisco router has become a commonly used network device, but we are not very clear about its storage classification. Here we will introduce it in detail. Memory category: 1: RAM: Random Access to memory, equivalent to computer memory 2: ROM: read-only memory. Some microcodes used to start and maintain the router are resident in the ROM. 3: FLASH Memory, equiva

: single two-way authentication: www.2cto.com 2.2, CHAP authentication: CHAP: Challenge Handshake Authentication Protocol, full name: challenge Handshake Authentication Protocol. CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified after the link is established. CHAP is safer than PAP because CHAP does not send plain text online, but instead sends a random number s

Router Access ADSL configuration detailed 1, Cisco router connection to the ADSL modem configuration: Note: The case for Beijing Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2500 router (dual Ethernet port), IOS 12.2 (T), Be able to realize LAN sha

This article uses VPN technology to achieve interconnection between two parts of the network, simulate ISP, close to practicality, the article mainly shows us the specific operation steps, mainly the input of basic commands. In this experiment, we use the Cisco 2600 router and VPN technology to achieve the network interconnection between one branch and two parts. To stay close to practicality, we still use

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

Cisco router security-TCP connections are common attacks on the network. In fact, most attacks are based on TCP connections, and a large amount of request data is sent to cause Server Denial of Service, is a connection attack. Next, I will take a Cisco router as an example to introduce how to intercept illegal TCP conn
