After we have a detailed understanding of DHCP, we also know that it also has some service settings in the applications of a variety of routers and switches. Here we will focus on the configuration of dhcp relay. This time, we will explain the content of the dhcp server corresponding to the vlan interface configuration. ◆ Dhcp relay Configuration Dhcp relay con

Although the wireless relay mode has a high cost, its advantages are still adopted by many network construction methods. Next, we will introduce the application of the wireless relay mode in the actual network construction of wireless networks. Go to the following link. Establish network connection in wireless relay Mode You can build a

CISCO PT Simulation Experiment (18) router DHCP server and relay configurationExperimental Purpose :Master the configuration method of router DHCP serverMaster the configuration method of DHCP relay AgentMastering the DHCP protocol and the principle and implementation process of the relayExperimental Background : with the expansion of the company's network, more and more office computers in the company, the

For DHCP Relay configuration content, we can analyze and learn through the following networking instance. First, we need to understand the network structure and then describe the configuration. Functional requirements and networking description DHCP relay Configuration "Configure Environment Parameters 』 1. the IP address of the DHCP Server is 192.168.0.10/24. 2. the DHCP Server is connected to port G1/1 o

The structure of the DHCP protocol is a complex part of knowledge. Here we will look at the relevant content in detail. Describes the fields of the DHCP protocol and related knowledge of DHCP Relay. Hope to help you. DHCP fields: When the op field indicates whether the current message is a Client request or when the server responds to 1, it indicates that the Client request is 2 and the server responds. The htype hlen field indicates the network hard

The core switch is still quite common. So I studied how to use the DHCP relay of the core switch to increase security performance. I would like to share it with you here and hope it will be useful to you. In a LAN environment, network virus attacks are always inevitable. Once a workstation is accidentally infected with a network virus, it cannot access the Internet normally. In addition, if you change the IP address at will, IP address conflicts may e

In the networking settings of the DHCP server, we sometimes involve DHCP Relay content. Next, we will explain how to use DHCP Relay to bind IP addresses and MAC addresses. I hope it will be helpful to you. Functional requirements and networking description Use DHCP Relay to bind IP addresses and MAC addresses "Configure Environment Parameters 』 1. the IP address

The relay drive current generally needs to be 20-40ma or larger, the coil resistance is 100-200 ohm, so the drive circuit should be added1. The transistor is used to drive the relay and the transistor's emitter must be grounded. Detailed circuits such as the following:NPN transistor PNP transistor NPN Transistor driver: When the transistor T1 base is input high, the transistor saturation conduction, the co

Article Title: Application of mail relay on a Linux server. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Yesterday I received a help call from the apprentice. He said that he deployed the Sendmail mailbox server on the Linux server. However, we encountered a strange problem. You cannot use the client software to

We have introduced the specific content of the wireless relay mode. I believe everyone knows about it. How can we use the AP and wireless relay in the networking, to achieve the perfect networking effect? Let's take a look at the following to see how different wireless networks are built by different numbers of wireless products. We need to consider the important factor of wireless

The online world is like a huge garden. Any technology is booming. Therefore, we need to pay attention to the basic network relay settings. Here we will introduce them in detail. Of course, not all wireless devices can achieve the purpose of Wireless Network Relay Settings and amplification function, which requires the combination of powerful firmware program, the routing device used by the author has refre

In the previous article, we discussed the principles and configurations of DHCP relay. I don't know what you know. Here we will take a look at the Advanced content about DHCP relay. Use a DHCP server (PC version) across subnets ). To improve network security, a larger LAN is usually divided into multiple subnets. However, the DHCP server can only provide services for the machines in this subnet. configuring

We have learned a lot about the DHCP service and so on. We should also have some knowledge about DHCP relay. We all know that DHCP relay is also a very important part of the content, so for this part of content, we will explain it in detail this time. For more information, see the following. Application Environment of DHCP relay Early DHCP protocols are only appl

In the process of learning the SIP protocol, we need to be clear about a concept, that is, the concept of SIP relay. In order to help you better understand this aspect, we use a comparison between Chinese and English translations to help you understand this aspect. The specific information is as follows: A sip Trunk is a logical connection between an ip pbx and a Service Provider's application servers that allows voice over IP traffic to be exchanged

The speed of network development is amazing. With the application of various network protocols, more and more devices can graft a variety of platforms to complete some of the settings that people need. Here we will discuss the working principles of dhcp relay. With the expansion of the network scale and the improvement of network complexity, the network configuration becomes more and more complex, and frequent computer location changes such as hosts o

When there are a large number of hosts in the LAN, if you set the IP address, default gateway,DNS server address and other network parameters, it is obviously a laborious and may not be pleasing method, then use DHCP to distribute the IP address, The ability to dynamically configure the network address parameters of each client greatly reduces the cost of management and maintenance. The following is an example of installing a DHCP server and a DHCP relay
