IP address management is the foundation of a successful logical design. This section describes how to develop a Scalable IP address management plan that supports Network resizing at any time. This section also describes the use and importance of key tools such as variable length subnet masks and route aggregation. It is equally important to select an appropriate
This chapter is dedicated to talk about network security, of course, it is relatively general to talk about the characteristics of network security, common network security vulnerabilities, and network security control methods. In the process of reference should be combined with information security
The concept of management is very important to all walks of life. If an enterprise cannot effectively manage it, the cohesion of the Enterprise will be very weak and the development of the Enterprise will be severely hindered; if an army is not managed, it will become a sandbox with no fighting power. If a network cannot be effectively managed, the use of such network
version 3rd (SNMP v3), Secure Shell Protocol (SSH), and role-based access control (RBAC) to prevent unauthorized management access. Equipment identification Cisco Fabric Manager uses standards-based protocols to automatically identify all devices and connect one or more networks to each other. All available switches, host bus adapters (HBAs), and storage devices can be identified. Identifying information
downloader periodically registers with the tracker, allowing the tracker to understand their progress, uploading and downloading data between the downloader via a direct connection, which uses the BitTorrent Peer-to-peer protocol, which is based on TCP. Therefore, the network administrator can control the maximum number of TCP connections to control the bandwidth consumption of BT network. filtering
In network protocols, we usually use SNMP Simple Network Management Protocol. Let's briefly discuss some basic information about this protocol. First, we will introduce the basic overview of this Protocol. The predecessor of SNMP (Simple Network

not only has the routing function, but also can switch between two different protocol sets.

btsoftware, the downloader periodically registers with the tracker so that the tracker can understand their progress. The downloader can directly upload and download data through a connection, this connection uses the BitTorrent peer protocol, which is based on TCP. Therefore, the network administrator can control the maximum number of TCP connections based on these characteristics to control the usage of network
whether a route involves OSPF, OSPF, RIP, and other routing protocols ). Multi-layer switching hardware-based layer-3 switching technology can free the router from the increased workload of forwarding "Single Point transfer IP" packets in the shared media network technology. Whenever there is a partial or complete switch path between two hosts, data packets are forwarded by the layer-3 switch function. Ho
NICs, hubs, or connections), you need to further check. In Figure 3 of www.2cto.com, Lao Zhang's "problem" is solved. I also want to say a few more words. When setting up a LAN, the network communication protocol depends on the network size, network compatibility, and network mana
Several router problems that the network management has to master (1) When do I use the multi-route protocol? When two different routing protocols need to exchange routing information, they need to use multiple routing protocols. Of course, route redistribution can also exchange route information. Multi-route protoco

Network management must read-common web commands If you've ever played with a router, you know the funny command abbreviations in the router.For example, "sh int" means "show interface". Now Windows 2000 also has a tool like the interface, called Netsh. We are under Windows 2000 cmd shell, enter Netsh to come out:netsh> prompt, enter int IP to display: interface ip> then enter dump, we can see the

, change "automatically obtain IP Address" to "specify IP Address". In this case, you can specify the IP address and subnet mask that cannot be filled in gray. 2. DHCP allocation To make TCP/IP protocols easier to manage, Microsoft and several vendors have jointly established an Internet standard-Dynamic Host configuration Protocol (DHCP ), it provides automatic TCP/IP configuration. The DHCP server provides clients with various configurations, such a

It contains protocols that design the logical transmission of packets over the entire network.There are three main protocols in this layer: Internet
Applications such as Firefox and OpenOffice are all shining, because they can be seen and touched, and are the cornerstone applications of a free desktop.
