The function and application of router LAN port

With the popularization of computer applications, millions of people in entertainment, communication, learning, work and other aspects of the realization of unprecedented information, greatly improve the quality of life and work. However, in the computer to bring people a lot of convenience at the same time, do you feel it also brings you a lot of "unsafe" negative factors? The management of routers on the port becomes the most important part of network management.

The Flying Fish Star volans-4150+ Router realizes the port based VLAN, can realize the port flow control, the data security shunt, but also has the unique data monitoring, the net information may through the Public Security Department supervision, strengthens the network management. Flying Fish Star is not only a powerful router, but also a network management switch. The biggest difference with other routers is that now 99% of the broadband router LAN port is an uncontrollable exchange structure, which is very useful for users to do intranet construction, and can support the Public Security Bureau required mirror monitoring port to match the special software access to the network monitoring.

One, Port based VLAN

A port based VLAN is the simplest and most efficient way to partition a virtual LAN, which is actually a collection of some exchange ports, and the network administrator only needs to manage and configure the switching ports, regardless of what device the switch port is connected to.


Flying Fish Star provides four LAN ports, these four LAN ports have the function of VLAN partitioning, so that different teams can be divided into different VLANs, different VLANs are not mutually accessible, ensuring security between the team.

There are separate working groups in an Internet café, for example, Internet Group, network Game Group, movie group and so on, different workgroup we can put them all different VLAN up, and then the VALN relative LAN port for traffic control, so as to ensure that the network game group has enough bandwidth, limit the download group traffic, Also does not affect the other user's bandwidth use, causes the network stable reliable not to drop the line, the management is also more convenient.

Second, the unique monitoring mode

The recent regular Internet cafes have to accept the relevant departments to monitor the requirements, flying fish technology to give full play to the advantages of independent research and Development, launched a series of high-performance enterprise-wide broadband router to support the port mirroring function, can easily realize the Internet bar monitoring, whether it is a new Internet café network or existing Internet cafes upgrade, Flying Fish star Volans must have a suitable for your products.

So-called port mirroring is the transfer data of one or more ports can be copied to the specified monitoring port to analyze and save as required. Each port of the switch is exclusive bandwidth, the use of a port-mirrored switch/router grab packet does not affect the speed, but also can be set according to the need for different grasp rules to achieve the best bag effect. Therefore, the use of ports mirroring the function of the switch or router to achieve the Internet café monitoring is the most convenient and most economical solution, but also the trend of Internet cafes network.

There are a lot of internet cafes in the network and did not consider the Internet café monitoring, so there is no choice with the port mirroring function of the equipment, the face of the requirements of Internet cafes monitoring can only be helpless? Don't worry, flying Fish star Volans has a complete set of solutions for you.

You can choose a flying Fish star VOLANS-4000 series with port mirroring capabilities of the enterprise broadband router. Flying Fish star Volans high-performance Enterprise-class broadband router using the Intel IXP network dedicated processor, 4 CPU distributed processing, the main frequency up to 533MHz, processing power, performance far more than common variety of broadband routers, good stability, support port mirroring, VLAN, Bandwidth control, such as specially tailored for the Internet café function, not only can easily achieve the Internet bar monitoring, but also to create efficient Internet cafes to provide strong support. In addition to provide free online software upgrades, to protect the future requirements for a higher level of application, flying fish Star characteristics of the online diagnosis of intimate services, but also to protect your Internet cafes for a long period of stable operation, complete lifting worries.

Flying Fish star volans4150+ can be set one of the LAN port as a mirror port, as a monitoring port, you can connect to the Ministry of Public Security monitoring machine, will not affect network performance, and no need to buy a webmaster switch.

Specific installation of the following figure:

In the Enterprise/Internet café with port mirroring function, can be very good for the internal network data monitoring and management, in the network failure, you can do a good fault location. Based on information security and the need to protect company secrets, there is also an urgent need for a port in the network to provide this real-time monitoring function.


Set up listening mode

1, volans-4150+ hardware to implement the port mirroring function, open this function does not affect the router forwarding capability.

2, network design and parameter configuration is simple. Only the listening host needs to be connected to the listening port.
