segment. Broadcast and unicast traffic within a VLAN is not forwarded to other VLANs. Even if the two computers have the same network segment, but they do not have the same VLAN number, their respective broadcast stream will not be forwarded to each other, thereby helping to control traffic, reduce equipment investment, simplify network management, improve network security. 1. According to the port to divide the VLAN Many VLAN vendors use the switch's ports to divide VLAN members. The ports t

level products. Cisco and 3Com are still the leader in market share, Atrica, Extreme, foundry and Nortel have also introduced technology-leading and performance-friendly products, and Intel and other manufacturers have introduced low-end but superior performance products. Huawei introduced the S8016-type high-end routing switch in 2001, with a back-panel capacity of up to 256Gbps. The products of each section flourish Cisco offers a Catalyst series

turned into a new master without a consistency problem, resulting in replication failure. 2. Interactive Primary server failover You can use only MHA failover instead of monitoring the primary server, and when the primary server fails, manually call MHA to fail. 3. Non-interactive primary failover The primary server is not monitored, but failover is automatically implemented. This feature applies to other software that has been used to monitor the state of the primary server, such as heartbeat

I. Lab Objectives Master the configuration of the switch tag VLAN; Master the basic configuration methods of layer-3 switches; Measure the test taker's knowledge about how to configure VLAN routing for a layer-3 switch; Layer-3 switches are used to implement inter-VLAN communication; Ii. Lab background An enterprise has two main departments: the technical department and the sales

With the development of the times and the development of science and technology, the layer-4 switch technology is also widely used for everyone. It can take corresponding actions based on the observed information, implement the key functions of bandwidth allocation, fault diagnosis, and access control over TCP/IP application data streams. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and

In order to improve the LAN operation and maintenance efficiency, we need to accumulate various switch troubleshooting experience at ordinary times so that the switch can be quickly rectified in case of a fault, this article has contributed several vswitch troubleshooting skills to my friends. I hope these content will help you! 1. Solve the trouble of resetting VLAN When managing and maintaining a LAN, if

Reasonable configuration solves the problem of Switch network loop, in the way of judging switch network loop, this paper makes a preliminary analysis of switch network loop problem from log information and enabled state, then rationally configures the switch and finally solves the

Mirror Port configurationMost switches support mirroring technology, which allows for easy troubleshooting of the switch. We call it "mirroring" or "Spanning". Mirroring is the copying of traffic from one port on the switch to the other (mirror port) for monitoring.CISCO3550 can be configured with 2 mirror portsCase: Mirroring Port 2~5 to Port 61.

Recent projects require that you create a branch on the SVN trunk, use a branch to make bug changes to the program, and develop new features on the trunk. The bugs on the branch are modified and can be merged onto the trunk after publishing. The project program can be switched between the trunk and the branch to achieve simultaneous maintenance of the backbone and the branch.1. Create a branchCreating a branch is actually a copy of the program to the specified branch directory, as shown in:Right

Command suSyntax: su [-] usernameCan be followed with '-' can also not, ordinary users su username is to switch to the root user, of course, the root user can also su to ordinary users. '-' The function of this character is, plus will initialize the current user's various environment variables, about the environment variables this part of the content Amin in the following chapters. The following Amin do a simple experiment to illustrate the differenc

Python itself does not provide a switch syntax, and in order to solve problems like switch branch requirements, we can use dictionaries instead of implementations.Solution Ideas: Handle the default in a switch statement using the fault tolerance of the Get method of the dictionary value Set the Vlaue of the dictionary to the corresponding method name

1 , what is the privileged mode of the switch? There are 6 modes of the switch. 1: The user execution mode (userexecmode). 2 : Privileged Execution Mode ( privilegedexec Mode ). 3 : Global configuration mode ( globalconfiguration Mode ). 4 : Monitor mode ( ROM Monitormode ). 5 : Safe Mode ( Setupmode ). 6 : Boot Mode ( Rxbootmode ). commonly used to have the and the 3.prompt PermissionsUser EXEC Mode "

In Ghost Win7 after a period of time, some users in the use of the system to work, occasionally will find that the input method of ghost Win7 can not be switched, and this switch is not to say that is all no way to use the input method, but maybe we can enter in the Web page, But when you return to the system word, you can't type it. What should I do then? The following small series to introduce you to the next ghost Win7 can not
