The rapid development of the network has created a favorable environment for the popularization of switches. Especially for a developing country like China with a large population and densely populated living environment, broadband entry into the home provides a broad foundation for the development of switches. Campus network, enterprise network and community network are in full swing. With the further popularization of networks and the increase in application demand, there is a lot of room for improvement in the development of switches.
Let’s take a look at the issues that today’s network administrators must pay attention to: How to put critical business data first? How to constrain transmission costs? How to control the transmitted traffic? How to eliminate the bottleneck in transmission rate? Network administrators must find ways to reduce the increasing network operation costs by reducing management burdens and losses from system downtime. Many studies have shown that the expenses involved in operation and management consume more money during the life of a product than the initial purchase of the product. Manageability becomes another key factor in evaluating overall value.
Therefore, the emergence of network managed switches is an inevitable result of the development of switches. The task of a network managed switch is to keep all network resources in a good state.
Network-managed switch products provide various network management methods based on terminal control ports (Console), web pages, and support for Telnet remote login networks. Therefore, network managers can monitor the switch's working status and network operation status locally or remotely, and manage the working status and working modes of all switch ports globally.
SNMP: It consists of a complete set of simple network communication specifications, can complete all basic network management tasks, has a small demand for network resources, and has some security mechanisms. The working mechanism of the SNMP protocol is very simple, mainly through various types of messages, namely PDU (protocol data unit).
Embedded Remote Monitoring (RMON) standard is used to track traffic and sessions, and is very effective in determining bottlenecks and blocking points in the network. The software agent supports 4 RMON groups (history, statistics, alerts and events), thereby enhancing traffic management, monitoring and analysis. Statistics are general network traffic statistics; history is network traffic statistics within a certain time interval; alarms can be alarmed when the preset network parameter limit value is exceeded; time represents management events.
Provides policy-based QoS (Quality of service). A policy refers to the rules that control switch behavior. Network administrators use policies to allocate bandwidth, priority, and control network access to the application flow. The focus is on bandwidth management policies required to meet service level protocols and how to issue policies to the switch.
Multifunctional light emitting diodes (LEDs) used at each port to represent port status, half-duplex/full-duplex and 10BaseT/100BaseT, and switching-stage state LEDs representing system, redundant power supply (RPS), and bandwidth utilization, form a comprehensive and convenient visual management system.
We have reason to believe that as the types of data services become increasingly complex, the application of network managed switches will be more extensive. Article entry: csh Editor in charge: csh
