Five precautions for re-planning the LAN

This article provides a detailed description of 10 Gigabit, deployment of PoE, redundancy, standards and maintenance, and network management tools, I hope you will have a clearer understanding of LAN planning after reading this article.

Is the LAN planning 10 Gb higher?

Today, 10 gbabit Ethernet and higher-speed Ethernet are beckoning to enterprises, but this does not mean that enterprises need to use this high-speed port in all LAN. In this case, enterprises often purchase the fastest device they think they really need, but their original 5% Mbps network only delivers performance. Although ensuring that the core switch can support a higher speed can truly reflect a cautious attitude, if the engineer tells the company that 10 Gigabit Switches are needed everywhere, it is suggested that enterprises waste money.

Do I need to deploy PoE in LAN planning?

More and more enterprises are using wireless LAN and IP phone technology. When PoE is available, wireless LAN access points are easy to install. An IP phone can be used to connect to a LAN and use power. The days of traditional PBX systems have been very limited; now there are a large number of more and more vendors are rolling in to ip pbx systems and handheld devices. Enterprises may not use wireless networks, but may say they do not use IP phone technology. However, if engineers can persuade enterprises to buy PoE switches, they should provide better services for enterprises. In addition, when the CIO decides to switch to WLAN or IP phone technology, the company does not have to replace these non-PoE switches.

Local Area Network Planning-Redundancy

The normal running time of the network is becoming increasingly critical to enterprises. Designers should plan network design to Facilitate network redundancy from both physical and logical perspectives. For example, a cable connection from a junction box to a core switch can use dual-optical fiber transmission. The rack-based core switch must have a dual-CPU expansion card. Enterprises should consider some components, such as gateway redundancy. However, if the enterprise does not correctly configure components to provide redundancy for the default gateway of the layer-3 IP address, the enterprise network will be suspended in the event of a fault, and even cause immeasurable losses.

Lan Planning Standards and Maintenance

When designing a company network, we should try our best to standardize different types of equipment, rather than using different types of switches in each wiring rack, even if all the devices come from the same manufacturer. Standardizing different types of hardware simplifies the configuration and fault diagnosis process.

Network management tools for LAN Planning

Although the network management tool may not be reflected in the enterprise's order form, it can play an immeasurable role in providing the maximum normal network running time. Software that regularly backs up all device configuration information to network sharing is simple but extremely useful. In addition, enterprises can consider the following situation: two switches on the Enterprise Network provide redundancy of the default IP gateway. If one of them fails, you don't realize it because the network is redundant. However, when another vswitch fails, enterprises will suffer from full network paralysis. How can this problem be solved? Enterprises can use a simple tool to ping all network devices and report their status, so as to easily avoid such faults.
