Some time ago, my colleague asked me a question about the DHCP configuration of the Cisco router. At that time, I did not give a positive answer, because this was my first time. In the following days, I have consulted relevant materials and are satisfied with the following answers. Share it with you now! In addition, most people do not know about the computer and do not operate these operations. Therefore, the customer asked us to allow any computer t

, You can provide additional protection for your Cisco router. These new enhanced login functions provide the following advantages: a login delay is created after consecutive login attempts are found. If too many login attempts fail, login is no longer allowed. Create the corresponding login information in the system log or send an SNMP trap to warn and record additional information about failures and disallow login. How do you know if your

As a leader in the current routing market, Cisco routers have advanced routing technology. Here we mainly analyze the future development of Cisco routers. Cisco routers are the leading enterprises in the routing industry, its market competitiveness is very strong, and Cisco also brings new opportunities to partners. Re

main line, and restore the backup line to the backup state.　　You can configure a route for a backup line in any way, but the bandwidth of the backup line is generally lower than that of the primary route, and there will be additional costs for dynamic routing. Therefore, Static Routing is generally used on the backup line. In Global Setting ModeIp route subnet address subnet mask adjacent router port addressIn principle, the backup line can be any li

Here we will give a brief explanation of the problem of Cisco Route DHCP configuration. Some friends may not know much about it, and most people do not know about the computer, so the customer asked us to allow any computer to access the LAN to access the Internet, so there is a process of configuring DHCP 2600. 2600 router we identify as: Cisco enters global mod

transmission rate does not exceed the target receiving rate. It is achieved by setting a window size for transmission; Error Control: ensure that the received data is continuous and there is no error. If there is a lost or lost PDU, no ACK packet is sent. Connection-oriented protocols include ATM, TCP, Novell SPX, and Apple Talk ATP; 2. Non-connection protocols Connection settings and termination are not included, and no throttling or error control is available. Non-connection protocols include

Configuration mode for Cisco routers Configuration mode Prompt Enter command Description User mode Route> User mode is the default mode when the router starts, provides limited access to the router, allows for non-destructive operations such as viewing the configuration parameters of the router, testing the connectivity of the router, etc., but cannot make any changes to the router configurati

The default value is 300 s, you can modify the global timeout value through ip reflexive-list timeout in global mode or set the timeout value in the corresponding application line, which takes precedence over the global setting value ). The basic format of the anti-list is: Ip access-list extended xxx Permit

to have a set of passwords at this level. To switch from user mode to privileged mode, the administrator needs to enter the enabel command and press the Enter key: Global Configuration Mode In privileged mode, we can now access global configuration mode. Here, we can make changes that affect the operation of the entire router. These changes include, of course, configuration changes. As an administrator, w

A reflexive Access table is actually an additional feature or feature that extends the I p named Access table. You can create an extension I p named Access table for all protocols that want to create a reverse table entry, using a P e r m i t statement. Also use the r E F l e c t keyword in each p e r m i t statement to indicate that the Access table needs to use a reverse opening table entry. In addition to the need to use the R E F l e c t keyword in one or more P e r m t statements, you must

With the development of China's routing industry, its market demand is also increasing. As a leader in the routing industry, Cisco routers have a very high market share. Telnet to the Cisco router for remote management is the choice of many network management, but the data transmitted through Telnet is in plain text, so this login method has a great security risk. 1.

Some of the comrades may not be very clear about the DHCP configuration of Cisco routers, and most people do not know about the computer, so, the customer asked us to allow any computer to access the LAN to access the Internet, so we had to configure DHCP 2600. 2600 router we identify as: Cisco enters global mode.
