Description
Technical Field
The invention relates to the field of data communication, in particular to a method for remotely managing a non-network management switch and a first switch.
Background
Ethernet is currently the most commonly used local area network technology, and ethernet switches are switches based on ethernet for data transmission. The ethernet switch is structured such that each port is directly connected to a host and typically operates in full duplex mode. The switch can simultaneously connect a plurality of pairs of ports, so that each pair of mutually communicated hosts can transmit data without conflict like exclusive communication media. The Ethernet switch is most commonly applied, has lower price and complete grade. Therefore, the application field is very wide, and the traces of the local area networks can be seen in large and small local area networks. Ethernet switches typically have several to tens of ports, essentially a multi-port bridge. In addition, the port rate can be different, and the operation mode can also be different, for example, 10M or 100M bandwidth can be provided, half-duplex, full-duplex, adaptive operation mode can be provided, and the like.
In a large-scale network, such as an office scene and a monitoring scene of a school, an enterprise, a hotel and a factory, a large number of terminals such as computers, cameras and door control terminals are connected to the network through a switch to perform data communication, a network topology needs to be generated, and the switch can be remotely managed to meet the requirements of batch configuration, fault detection and processing in operation and maintenance.
Taking a typical monitoring network as an example, for the switch, the monitoring network is divided into 3-layer networking, which are an access switch, a convergence switch, and a core switch, respectively. An access switch generally has a plurality of ports connected with a plurality of camera terminals, and one port is used as an uplink port to transmit data to a convergence layer; the convergence switch is mainly connected with the switch of the access layer and transmits data to the core layer, and the core switch transmits the data to the video storage and display equipment.
In the existing technical scheme, the core and aggregation switches are both network-manageable switches, and the access switches are divided into two types, namely network-manageable switches and non-network-manageable switches. The network management-capable switch is provided with a CPU system (comprising a CPU processor, flash and DDR), and can be used for configuring VLAN and various protocols, packaging, analyzing message contents, reporting fault information, receiving remote instructions and executing in addition to the basic switching function. The non-network management switch is not internally provided with a CPU system, only has a switching function, can only forward a standard Ethernet message according to rules, and cannot be managed. Since the number of access switches required is the largest, low cost non-network managed switches are very common in existing networks.
If the access switch is a network-manageable switch, the access switch can store product information such as manufacturer, model, serial number and the like in the CPU system and has the capability of packaging the information into a message. When a network manager needs to generate the network topology, detailed network topology including the model, the quantity and the connection relation can be generated only by reading and analyzing the message packaged with the product information through the network. If the access switch needs to be subjected to operations such as VLAN division, port operation, restarting and the like, only the instruction is issued through the network, thereby greatly facilitating the operation and maintenance of the network.
If the switch is a non-network management switch, the type, the number and the connection relation of the switches of the access layer cannot be identified through the network, remote control cannot be achieved, great difficulty is caused to service debugging and fault location, even if one switch needs to be restarted, the switch can only be manually operated on site, and the reliability and the operation and maintenance efficiency of the network are greatly reduced.

The embodiments of the present invention are further described below with reference to specific application scenarios:
fig. 9 is a design of an uplink interface isolation circuit of a non-network management switch, as shown in fig. 9, an ethernet port transmits differential signals by using 4 pairs of twisted pairs, and is represented by MX1-MX4 in fig. 9. At the step-down (isolation transformer) there is one center tap per pair of differential lines, denoted CT1-CT4 in fig. 9, which connects the bob smith circuit for electromagnetic filtering for a common switch. The embodiment of the invention adds the low-voltage direct-current level signal on the bypass (without influencing the electromagnetic filtering function) of the 4-tap bob smith circuit of the upper connection port of the non-network management switch and carries out information interaction by utilizing a high level state and a low level state. The low-voltage direct current signals added to the taps can be transmitted to the convergence network management switch through the network cable, and because data on the network cable is transmitted by using differential signals, the added direct current signals cannot influence the original data transmission. The purpose of the low voltage signal is to ensure that the voltage on the network line is not a safety hazard, while ensuring the transmission distance.
The dc signal control module in fig. 9 can use a low-cost MCU, a single chip or other programmable devices to cooperate with peripheral circuits to achieve the low-cost advantage of maintaining a non-network managed switch, detect and control high and low changes of dc signals, and perform remote management actions.
Fig. 10 is a design of an aggregation network management switch (i.e., a first switch) isolation circuit, as shown in fig. 10, and the main differences from a non-network management switch are as follows: the convergence network management switch is provided with a CPU system, and the detection and control for increasing the direct current signal are realized by the CPU system, specifically, the convergence network management switch can be realized by a sending module in the CPU system.
An equivalent interconnection diagram of the converged network management switch and the non-network management switch is shown in fig. 11 (an example in which an ethernet port of the converged network management switch is connected to an uplink port of a non-network management switch), and the switching and management processes are described as follows:
step one, acquiring the model of a non-network management switch: after startup and interconnection, the CT1 (transmitting the direct current signal 1) is controlled by the convergence network management switch, and the CT2 (transmitting the direct current signal 2), the CT3 (transmitting the direct current signal 3) and the CT4 (transmitting the direct current signal 4) are controlled by the non-network management switch. The CT1 sends a high level '1', the non-network management switch receives the high level signal and controls the CT2-CT4 to output high and low levels, 8 combinations are available in total and can represent 8 product models, and as shown in the table 1, the convergence network management switch identifies the level state of the CT2-CT4 and compares the combination with the combination stored in the CPU system to know the product model of the connected non-network management switch. Through the first step of interaction, the product model of the non-network management switch can be remotely obtained, and a network management topological graph is generated.
| Combination serial number | CT2 | CT3 | CT4 | Means of |
| 1 | 0 | 0 | 0 | Model 1 |
| 2 | 0 | 0 | 1 | Model 2 |
| 3 | 0 | 1 | 1 | Model 3 |
| 4 | 0 | 1 | 0 | Model 4 |
| 5 | 1 | 0 | 0 | Model 5 |
| 6 | 1 | 0 | 1 | Model 6 |
| 7 | 1 | 1 | 0 | Model 7 |
| 8 | 1 | 1 | 1 | Model 8 |
TABLE 1
Step two, state switching: after the convergence network management switch obtains the product model, the convergence network management switch controls the CT1 to output a low level of 0, informs the non-network management switch that the product model obtaining is finished, and enters a management state of fault reporting and remote configuration. If the product model is to be obtained again, the convergence network management switch controls the CT1 to output a high level 1. After entering the state of fault reporting and remote configuration, CT2 and CT3 are switched to be controlled by the convergence network management switch, and CT4 is still controlled by the non-network management switch.
Step three, remote configuration: in the states of fault reporting and remote configuration, the convergence network management switch can control the CT2 and the CT3 to output 4 combinations of high and low levels to represent 4 common configuration actions, as shown in table 2. The non-network management switch monitors the level combination values of the CT2 and the CT3 to carry out corresponding configuration operation.
| Combination serial number | CT2 | CT3 | Means of |
| 1 | 0 | 0 | Complete machine reset |
| 2 | 0 | 1 | Standard exchange |
| 3 | 1 | 0 | Isolated mode |
| 4 | 1 | 1 | Flow control closure |
TABLE 2
In the state of fault reporting and remote configuration, the CT4 is controlled by a non-network management switch, outputs a low level '0' to indicate that the local computer has no fault, outputs a high level '1' to indicate that the local computer has the fault, and can report a common fault message, such as over-temperature or abnormal fan, to the convergence network management switch. The convergence network management switch monitors the level value of the CT4 in real time to know whether the connected non-network management switch has faults and abnormity.
The embodiment of the invention has the beneficial effects that: under the condition of not increasing a CPU system, the complete network topology can be identified and generated according to the model of the non-network management switch, meanwhile, the non-network management switch can remotely report fault information and can also be remotely configured, the management capability is realized under the condition of keeping the characteristic of low cost, and the reliability and the operation and maintenance convenience of the network are greatly improved.
