Yamaha's "SWX2200" that realizes a problem -resistant network

In the small business network without a full -time manager, it is important that the disability is not occurring and the one can respond quickly to the disability.If you want to build a network that is resistant to such troubles, the combination of Yamaha's router and the switch "SWX2200 Series" is the strongest.

Many of the causes of network troubles are "I don't know, but it's troublesome"

　In Japan, the cost of broadband services is cheaper than in other countries, especially the Internet connection of optical fiber can be used at a very low price.For this reason, even in small business sites where there are few employees, they should be fully utilizing the Internet with peace of mind.Conversely, if an internal network (LAN) has a failure, the work will have a major impact.Network disorders are phenomena that the Internet cannot be used or communication is slow, but the causes and effects are diverse.

　According to Yamaha's survey, which has been handling network equipment for a long time, the main troubles of LAN are as follows.In fact, 35 % of the total is a LAN loan that connects the same switches to double each other.If a loop is made between the switches, the same packet will continue to spin around without any destination on different routes.As a result, the transmission of the looped packet expands as a violent traffic like a storm, and communication is not possible (broad casttom).Subsequently, "unintended power sources", "cables omission", and "device failure" are listed, and the remaining 27 % are "other causes".

LAN's main trouble causes

　If you look at this, it is honestly the cause of "unstable", but if the network straddles multiple floors and bases, it is extremely difficult to identify the cause of the trouble.It would not be realistic for administrators to go to the site and check out the cables and power out of power.

The power of visualization realized with Yamaha routers and switches

　In order to quickly detect and deal with these disabilities, "visualization of the network" is essential.If you can understand which port the router or switch is connected, and how it is connected, you can quickly detect the obstacle.Furthermore, if the disability point is quickly identified by the management tool, the recovery can be performed quickly.Of course, not only visualization, but also "high impairment" is important.For example, if you can use another link even if the cable is missing, or if a LAN loop is prepared to suppress the broad casttom, this problem will not fall.

　The Yamaha switch "SWX2200 Series" realizes such "visualization of the network" and "high disability" and realizes a network that is resistant to trouble.

Yamaha's Gigabit Switch "SWX2200 Series"

　The SWX2200 is Yamaha's first LAN switch, which has been working as a router for a long time, with 8 ports and 24 ports models.Looking at the appearance alone, it looks only as a general switch, but it has the only characteristic that you can set and manage it from the latest yama Haruta *.With one Yama Haruta, up to 32 SWX2200 connected to the subordinate can be controlled by up to 32 units, so one router is used.In other words, despite the physically different housing, it can be treated as if the LAN port of the router has increased.

^{* The corresponding routers are "RTX1200", "RTX810", "NVR500", and "FWX120" (as of March 2013)}

　What is nice for the user is the function that automatically detects the connection status (topology) of routers and switches.When you open the menu from the Yamaharuta GUI tool, the latest network status is displayed in real time with icons of equipment such as the front port of the switch and SWX2200.Even if the switch is added later, the topology will be displayed according to the connection status.

You can check the switch connection status from the router GUI

　How to use is easy.After completing the router and the switch, turned on the power, and accessed the router GUI with a web browser.In the top menu, select the basic settings in "Switch control", and turn on "Use" the switch control function for "LAN interface".This enables control of SWX2200, so click the "Run" button on the connected LAN interface.A list of switch links connected to LAN1 are listed.In addition to the icon display that is easy to grasp the topology, you can also select a detailed display that can be checked up to the connection state.Just mouse over to the colored port, the pop -up is displayed to the link status and frame counter.

It will be easier to grasp the connection status with detailed display

　It is also possible to list the PC connected to the switch.If you find an illegal terminal, you can manually close the port itself and block communication.If you use the function of the router, you can refuse connections other than registered PCs by registering the MAC address of the connection terminal in advance.In terms of security, SWX2200 is full of useful functions.

　Switch settings can also be easily performed from Yama Haruta's GUI.For example, VLANs that make up different LANs in port units are essential functions for companies from the viewpoint of security, but it is surprisingly troublesome to set which ports belong to which VLAN.In addition, the method of setting differs depending on the type of VLAN, such as multiple VLANs to which one port belongs to multiple VLANs, and tag VLANs that give their VLAN ID to the frame.In that regard, SWX2200 can be intuitively operated from Yamahalter's GUI.

　SWX2200 has excellent disability.Regarding the LAN loop that was the most common cause of the LAN main troubles mentioned above, the loop state is displayed in the GUI.In addition to posting an alert on the loop detected port, the target port can be automatically shut down.It is also possible to search for the connection location of the terminal that causes a disability with a MAC address, IP address, host name, etc.

　Also, even if the switch is broken, the user is automatically injected from the router if the user replaces the broken device with an alternative.Since the switch setting information is held by the yama harter, there is no need to set it manually.

If you replace the failed SWX2200 with a substitute, the setting will be automatically applied from the router.
