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
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
With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with their stable performance and good scalability.

Recently, a friend asked me how to configure static NAT for a Cisco router to allow Internet users to access the Intranet Web and email servers through a Cisco router. Obviously, this function requires NAT between the public IP address and the Intranet IP address. The following are the specific implementation methods.
The market demand for Cisco routers has been very high. Here we mainly analyze the detailed knowledge of Cisco router configuration and RJ45 console connection, for accessing and configuring I0S on a new router, we must communicate with the Console port.
After connecting a console terminal with the Console port configu

It is very important to know some common knowledge about CISCO routers. Here we mainly explain the CISCO router tutorial, which provides a detailed analysis from configuration to access methods. This document uses Cisco2620 as an example to describe how to configure the vro and remote access, this article discusses how to use the DHCP service function of the inte
Recently changed jobs, the company more than 40 people share a 20M bandwidth wireless network, the router for Cisco R2911. Boss, let me make a cacti to monitor Cisco routed network card traffic.

In general, you can configure your router in 5 ways:
1.Console Port connection terminal or running terminal simulation software of the microcomputer;
2.AUX Port Connect modem, connect with remote terminal or computer running terminal simulation software by telephone line;
3. Via the TFTP server on the Ethernet;
4. Adoption of

Some time ago, someone familiar with me asked me how to set up a bridge on a Cisco router )? At that time, due to the relationship between work, I just briefly talked to him. Today, we set up a Cisco router as a complete configuration command for bridging. Through this instance, you can learn how to use a
address of the TFTP server be entered. After the Server IP address is correctly entered, the router also requires the network administrator to provide the configuration file name to be backed up. Generally, we recommend that you use a file name that is easily remembered by the Administrator. At this time, the router will prompt the Administrator to press YES to confirm the operation.

For enterprise users, multi-device port access control can optimize the network more reasonably. Here we analyze in detail how to configure a Cisco router to implement this function. You only need a CISCO router with an asynchronous module or a router with a built-in asynchr
The importance of vro configuration is self-evident. Here we mainly analyze the Cisco router configuration statements in detail, and share them with you here, hoping to help you.
