Connected managed switches ring or unmanaged switch ring, realize data from unmanaged switch to management type
The transmission of the transmission of interchanger or data from unmanaged switch to unmanaged switch.
In addition, managed switches further include fault detection module, failure with unmanaged switch looped network component devices
Detection module is connected with central control module, and in use, fault detection module is used to detect central control module in real time
Whether exception is occurred, also, after detecting that exception occurs in central control module, fault detection module can generate failure letter
Number.By the setting of fault detection module, the working status of central control module can be monitored in time, further, it is possible to look into time
See the exception of central control module, and generate fault-signal.
In addition, managed switches further include fault alarm module with unmanaged switch looped network component devices, the event
Barrier alarm module is connected with above-mentioned fault detection module, and in use, fault alarm module can receive failure letter
Send out alarm signal after number, it is necessary to illustrate, the form of alarm signal include audible alarm, light warning and its
Alarm of his form etc., user can flexibly be chosen according to usage scenario., can be timely by the setting of fault alarm module
Inform related management personnel's guilty culprit, and then improve the ability to extraneous early warning, it is convenient and efficient.
In conclusion managed switches provided in this embodiment include with unmanaged switch looped network component devices:
Central control module, managed switches and unmanaged switch, the connection pass of all parts in the looped network component devices
System is as follows:The managed switches and unmanaged switch that head and the tail sequentially connect form looped network business link, in above-mentioned looped network
In service link, the quantity of managed switches is at least one, in the looped network component devices, central control module and management
Type interchanger is connected, and is that central control module is used to send control data to managed switches first in use, it
It is that managed switches are used to shield the network storm in looped network afterwards, also, managed switches will also control data
Unmanaged switch is sent to, afterwards, unmanaged switch is used to pass through looped network business link, realizes to control data
Transmission, so as to form loop network, is required for configuration CPU mini system unit modules, to realize management in managed switches
Function, can thus increase the use cost of looped network composition, and in the managed switches and unmanaged switch looped network group
Into in device, pass through setting at least one central control module and a managed switches and Duo Tai unmanaged switch
Put, so as to greatly save the cost of loop network composition, reduce service difficulty, it is convenient and efficient.
