Description
Technical Field
The present invention relates to the field of electronic devices, and in particular, to a method for modifying an ethernet switch configuration and an ethernet switch.
Background
Ethernet (Ethernet) refers to the baseband lan specification created by Xerox corporation and jointly developed by Xerox, Intel and DEC corporation, using the IEEE 802.3 standard, is the most common communication technology used in existing lans today. An Ethernet Switch (Ethernet Switch) is an Ethernet multi-port bridge device, which has multiple ports with different port rates, and can simultaneously perform data communication between multiple source ports and multiple destination ports. An ethernet switch generally includes a Central Processing Unit (CPU), a memory, a Media Access Control (MAC) controller, and a physical layer (PHY) controller, wherein a Random Access Memory (RAM), an Electrically Erasable Programmable Read Only Memory (EEPROM), and a FLASH memory (FLASH) may be used as the memory of the ethernet switch. Part of the ethernet switch chip will integrate the MAC controller and PHY together.
After the ethernet switch is powered on and started, hardware initialization is firstly performed through a bootstrap program, for example, a CPU and a memory are initialized, then a designated running program in the memory is loaded into a RAM through the bootstrap program to run, finally, a configuration file in the memory is read through the designated running program, and the value setting of registers of a MAC controller and a PHY of the switch is performed according to parameters of the configuration file to complete the whole starting process.
And modifying the configuration of the Ethernet switch, namely modifying the value of the MAC controller register of the Ethernet switch. The most common method at present is to read and write the register of the MAC controller according to a specific protocol, such as hypertext transfer protocol (HTTP), TELNET protocol (TELNET), Simple Network Management Protocol (SNMP), or a running program that logs in the RAM of the ethernet switch through a serial interface (SerialInterface).
Ethernet switches are classified into network management type switches and non-network management type switches. Because the RAM space of the network pipe type switch is sufficient, a network management system can be operated generally, a user is allowed to log in the network management system operated in the ethernet switch through various protocols, such as an IOS network management system of cisco, and then the register of the MAC controller is read and written through the network management system to perform device configuration. The non-network management type exchanger can only operate a specific software program on a computer generally because the RAM space is smaller, and the register of the MAC controller is read and written for configuration by accessing the software program which is operated in the RAM space and is matched with the specific software through the serial interface.
According to the current method for modifying the configuration of the Ethernet switch, the configuration is difficult to carry out on occasions lacking computers, for example, the switch is installed in a cell unit distribution room, and if a portable notebook computer is not available, the equipment is difficult to configure so that the equipment works normally. Even if a computer can be used, the device configuration is difficult to be performed under the condition that the specific configuration of the network management program cannot be confirmed, for example, an ethernet switch operating in a network cannot be confirmed or forgotten, if the switch manages an IP or manages a VLAN port, the device network management system cannot be accessed by using a remote login protocol such as HTTP, TELNET, SNMP and the like, so as to configure the device. For the non-network management type switch, a common user cannot obtain a specific software program and cannot modify the configuration, for example, the default configuration of the non-network management type switch is set when the equipment leaves a factory, and if the default configuration is not suitable for the network environment of the user, the common user cannot modify the switch configuration to solve the problem.
To sum up, the current method for modifying the configuration of the ethernet switch cannot be performed without a computer; moreover, for the network management type switch, the specific configuration of the network management program needs to be known; for the network-management-free type switch, an ordinary user has no way to modify the configuration of the switch according to requirements.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, fig. 1 is a flowchart of a method for modifying the configuration of an ethernet switch according to an embodiment of the present invention, including the following steps:
step 101, presetting configuration modification conditions, wherein the configuration modification conditions are corresponding relations of port PHY states, configuration function items and configuration options of the Ethernet switch.
The port PHY state described herein refers to the combination of all port states in the ethernet switch. In the ethernet, the ethernet ports include three network ports of RJ45, BNC and AUI according to different transmission media. Each port state is determined by one or more combinations of its duplex state, operating rate, and enable state, depending on the port. Taking the RJ45 port of a gigabit ethernet as an example, each RJ45 port has three operating rates: 10M, 100M, 1000M; two duplex states: half duplex and full duplex; two enabled states: an enabled (UP) state and a not enabled (DOWN); when the enabling state of the RJ45 port is not enabled, only one DOWN state is available, and when the enabling state of the RJ45 port is enabled, 6 states of 10M/Half duplex (Half), 10M/Full duplex (Full), 100M/Half, 100M/Full, 1000M/Half, and 1000M/Full exist, so that 7 port states are available for each RJ45 port of gigabit Ethernet. Assuming 24 RJ45 ports in an ethernet switch, the ethernet switch has a total port state combination of power 24 of 7. Note that the port according to the present invention is not limited to the RJ45 port.
The configuration function item is also a configurable function item of the ethernet switch, such as a flow control function; for any configuration function item, a specific configuration option corresponding to the configuration function item is required, for example, the configuration options for flow control may be: enable flow control, or disable flow control.
The specific meaning of the corresponding relationship among the port PHY state, the configuration function item and the configuration option of the Ethernet switch is as follows: when the port PHY state of the Ethernet switch is the same as the port PHY state in the corresponding relation, the configuration of the configuration function item in the corresponding relation is modified into the configuration option in the corresponding relation.
And 102, when the configuration of the Ethernet switch needs to be modified, setting the port physical layer (PHY) state of the Ethernet switch according to a preset configuration modification condition.
In this step, after the port PHY state of the ethernet switch is set, the staff needs to wait for at least a preset time to allow the port PHY state of the ethernet switch to be changed, otherwise, it may cause a failure in modifying the configuration of the ethernet switch. Here, the preset time is a time interval for detecting the PHY state of the port of the ethernet.
In this step, the ethernet switch periodically detects the PHY status of its own port, and modifies the configuration of the ethernet switch when the PHY status of its port meets the preset configuration modification condition. Here, the method for determining whether the detected port PHY state satisfies the configuration modification condition includes: and searching the preset configuration modification condition according to the port PHY state, wherein if the port PHY state in one configuration modification condition is the same as the detected port PHY state, the detected port PHY state meets the configuration modification condition.
In addition, before modifying the configuration of the configuration function item in the configuration modification condition, it may be determined whether the current configuration of the configuration function item in the configuration modification condition is the same as the configuration option in the configuration modification condition, if so, the configuration of the configuration function item in the configuration modification condition does not need to be modified, and the current configuration is still maintained, and if not, the configuration of the configuration function item in the configuration modification condition is modified to the configuration option in the configuration modification condition.
In fig. 1, the ethernet switch detects the PHY status of its own port at fixed time intervals, and triggers configuration modification when it is determined that configuration modification is required. In fact, a manner of immediately triggering the ethernet switch to perform configuration modification may also be adopted, for example, a trigger signal is preset, and is manually triggered after the port PHY state is set, and after receiving the trigger signal, the ethernet switch immediately detects its own port PHY state, and performs corresponding configuration modification according to the detection result. However, since the setting of the trigger signal also requires additional software and hardware support, the scheme shown in fig. 1 is mainly further described in the present invention.
In the technical solution of the present invention shown in fig. 1, a configuration switch may be further provided. Before modifying the configuration of the ethernet switch, further comprising: starting a configuration switch to allow the configuration of the Ethernet switch to be modified; before modifying the configuration of the configuration function item in the configuration modification condition, further judging whether a configuration switch is turned on, if so, modifying the configuration of the configuration function item in the configuration modification condition to configure the configuration item in the configuration modification condition, otherwise, still keeping the current configuration of the configuration function item in the configuration modification condition unchanged; after the configuration modification of the ethernet switch is completed, further comprising: and closing the configuration switch and forbidding modifying the configuration of the Ethernet switch. The configuration switch is arranged, so that abnormal change of the configuration of the switch caused by non-active operation of a user can be avoided, and the times of non-forced erasing of the memory can be reduced.
The enabling condition of the configuration switch may be that the port of the ethernet switch is negotiated to a specified PHY state, that is, a corresponding relationship between the opening of the configuration switch and the PHY state of the port of the ethernet switch, and a corresponding relationship between the closing of the configuration switch and the PHY state of the port of the ethernet switch are preset.
The method for turning on the configuration switch comprises the following steps: setting the port PHY state of the Ethernet switch as a port PHY state corresponding to the starting of the configuration switch, and waiting for at least preset time; and when the Ethernet switch detects that the port PHY state is the state that the corresponding port PHY is started by the configuration switch, setting the configuration switch to be in the starting state.
The method for closing the configuration switch comprises the following steps: setting the port PHY state of the Ethernet switch as the port PHY state corresponding to the closing of the configuration switch, and waiting for at least preset time; and when the Ethernet switch detects that the port PHY state is the port PHY state corresponding to the closing of the configuration switch, the configuration switch is set to be in the closing state.
The invention can also preset the configuration validation mode. The configuration validation mode comprises immediate validation and validation after restart. The immediate effect mode is simple and quick, and is suitable for the configuration of the network-administration-free type switch. The effective mode after restarting can avoid the problems of network instantaneous interruption and network topology oscillation caused by configuration modification, and is suitable for the configuration of the network management type switch.
The invention also presets the parameters corresponding to the configuration switch.
In the immediate effect mode, the method for setting the configuration switch to the on state is as follows: setting the parameter corresponding to the configuration switch as a value corresponding to the opening of the configuration switch, for example, the value corresponding to the opening of the configuration switch is 1; the method for setting the configuration switch to be in the closed state comprises the following steps: and setting the parameter corresponding to the configuration switch to a value corresponding to the closing of the configuration switch, for example, the value corresponding to the closing of the configuration switch is 0.
In general, for a non-network management type switch, the value of the MAC register corresponding to each configuration function item can be directly modified. Therefore, in an immediate effect manner, for the network-managed switch, the method for modifying the configuration of the configuration function item in the configuration modification condition to the configuration option in the configuration modification condition in step 102 is as follows: modifying the value of the MAC register corresponding to the configuration function item in the configuration modification condition into the value corresponding to the configuration option in the configuration modification condition, for example, the value corresponding to the configuration modification condition is 1 when the configuration is enabled, and the value corresponding to the configuration modification condition is 0 when the configuration is not enabled; for the network management type switch, it is generally not allowed to directly modify the MAC register value corresponding to each configuration function item. However, since the network management system operating in the network management type switch has configuration parameters corresponding to each configuration function item, the purpose of modifying the configuration of the configuration function item can be indirectly achieved by modifying the parameters corresponding to the configuration function item in the network management system. Therefore, in an immediate effect manner, for the network management type switch, the method for modifying the configuration of the configuration function item in the configuration modification condition to the configuration option in the configuration modification condition in step 102 is as follows: and modifying the configuration parameters in the network management system corresponding to the configuration function items in the configuration modification conditions into values corresponding to the configuration options in the configuration modification conditions. The parameters in the network management system are modified, for example, the technical scheme of the invention is realized in the network management system, and the direct modification of various parameters in the network management system is supported, which belongs to the problem of specific implementation and is not described any more.
If the configuration validation mode is set to be valid after the restart, step 102 sets a port physical layer PHY state of the ethernet switch according to a preset configuration modification condition, and waits for at least a preset time, further includes: restarting the Ethernet switch after power down; the method for modifying the configuration of the configuration function item of the configuration modification condition as the configuration option of the configuration modification condition in step 103 is: and modifying the value of the MAC register in the configuration file stored in the memory space of the Ethernet switch corresponding to the configuration function item of the configuration modification condition into the value corresponding to the configuration option in the configuration modification condition.
In an effective manner after the restart, in a process of starting the configuration switch, setting the port PHY state of the ethernet switch to a port PHY state corresponding to the start of the configuration switch, and waiting for at least a preset time, further comprising: restarting the Ethernet switch after power down; the method for setting the configuration switch to be in the opening state comprises the following steps: modifying the value corresponding to the configuration switch in the configuration file stored in the memory space of the Ethernet switch into the value corresponding to the opening of the configuration switch; in the process of closing the configuration switch, the setting the port PHY state of the ethernet switch to the port PHY state corresponding to the closing of the configuration switch, and waiting for at least a preset time, further includes: restarting the Ethernet switch after power down; the method for setting the configuration switch to be in the closed state by the Ethernet switch comprises the following steps: and modifying the value corresponding to the configuration switch in the configuration file stored in the memory space of the Ethernet switch into the value corresponding to the closing of the configuration switch.
In the effective mode after restarting, the Ethernet switch can realize the purposes of opening and closing the configuration switch, modifying the configuration and the like by reading the updated configuration file in the memory in the power-off restarting process.
The configuration validation mode can be preset by the manufacturer of the Ethernet switch or can be selected by the user. When the user selects the configuration effective mode, the invention also presets the parameter corresponding to the configuration effective mode, and also presets the corresponding relation between the configuration effective mode and the port PHY state, namely the corresponding relation between the port PHY state of the Ethernet switch and the immediate effective mode, and the corresponding relation between the port PHY state of the Ethernet switch and the effective mode after restarting; before the configuration switch is turned on, a configuration validation mode can be further set, and the specific setting method comprises the following steps: and setting the port PHY state of the Ethernet switch as the port PHY state corresponding to the required configuration effective mode, waiting for at least preset time, and setting the parameter corresponding to the configuration effective mode as the value corresponding to the immediate effective mode or the effective mode after restarting when the Ethernet switch detects that the port PHY state corresponds to the immediate effective mode or the effective mode after restarting. Here, the setting configuration validation manner only needs to be set once.
It should be noted that, in the above method for modifying the configuration of the ethernet switch, the waiting time is at least a preset time because: the time interval for detecting the port PHY state of the ethernet switch is the preset time, and if the waiting time is less than the preset time, it is possible that the port PHY state before the change is not detected before the change. For example, after the port PHY state setting configuration switch is turned on, and before the ethernet switch detects the port PHY state, the port PHY state is set to the state corresponding to the enable traffic control, and the configuration switch is not actually turned on at this time.
The following describes the method for modifying the configuration of the ethernet switch by taking the example of modifying the flow control function of the most common ethernet-type switch without network management, which has 24 RJ45 ports. Suppose that the ethernet switch leaves the factory as follows:
1. the default flow control function of the switch is in a closed state, namely, an disabled state; configuring the switch to be in a closed state; the configuration effective mode of the switch is an immediate effective mode;
2. when the P1-P21 ports are in a Down state and the P22-P24 ports are in a 10M/Half state, the specific configuration of the flow control function of the exchanger is modified to enable flow control;
3. the P1-P8 ports are in a 10M/half state, and when other ports are in a Down state, the configuration switch of the switch is modified to be in an open state, so that the configuration of the switch is allowed to be modified;
4. when the P9-P16 port is in a 10M/Half state and other ports are in a Down state, modifying the configuration switch of the switch to be in a closed state, and forbidding modifying the configuration of the switch;
5. when the P17-P24 port is 10M/Half, and other ports are in a Down state, the configuration effective mode of the modified switch is effective after restarting.
If a user wants to modify the configuration validation mode of the switch into validation after restarting, and modify the configuration of the flow control function of the switch into enabling flow control, assuming that the period of detecting the port PHY state by the Ethernet switch is 5 seconds, the specific configuration steps are as follows:
A. connecting P17-P24 ports of the switch with a HUB (HUB) with 8 ports and a working speed of 10M by using a common twisted pair, connecting other ports with no network cable, waiting for at least 5 seconds after the connection is finished, and modifying the configuration effective mode of the switch into effective mode after restarting; and in the waiting time, the Ethernet switch detects the state of the port PHY, and modifies the configuration effective mode into the effective mode after restarting according to the state of the port PHY.
B. Connecting the P1-P8 ports of the switch with a HUB (HUB) with 8 ports and working speed of 10M by using a common twisted pair, not connecting the other ports with a network cable, waiting for at least 5 seconds after the connection is completed, and powering down the switch for restarting. And in the waiting time, the Ethernet switch detects the PHY state of the port, modifies the value corresponding to the configuration switch in the configuration file stored in the storage space of the Ethernet switch into the value corresponding to the open configuration switch according to the PHY state of the port, and takes effect after the switch is restarted. So far, a configuration switch of the switch is turned on, and the configuration of the switch is allowed to be modified;
C. connecting the P22-P24 ports of the switch with a HUB (HUB) with 8 ports and working speed of 10M by using a common twisted pair, not connecting the other ports with a network cable, waiting for at least 5 seconds after the connection is completed, and powering down the switch for restarting. And in the waiting time, the Ethernet switch detects the PHY state of the port, modifies the value corresponding to the flow control function in the configuration file stored in the storage space of the Ethernet switch into the value corresponding to the enabled flow control according to the PHY state of the port, and takes effect after the switch is restarted. At this point, the flow control function of the switch is started, namely enabled;
D. connecting the P9-P16 ports of the switch with a HUB (HUB) with 8 ports and working speed of 10M by using a common twisted pair, not connecting the other ports with a network cable, waiting for at least 5 seconds after the connection is completed, and powering down the switch for restarting. And in the waiting time, the Ethernet switch detects the PHY state of the port, modifies the value corresponding to the configuration switch in the configuration file stored in the storage space of the Ethernet switch into the value corresponding to the closed configuration switch according to the PHY state of the port, and takes effect after the switch is restarted. At this point, the configuration switch of the switch is closed, prohibiting the configuration of the switch from being modified.
Through the A, B, C, D steps, the user can modify the configuration of the flow control function of the Ethernet exchanger without the help of a computer. Because a gigabit ethernet switch with 24 RJ45 ports has 24 port state combinations of power 7, the basic function setting of the switch, the factory default setting restoration, and the like are completely satisfied, and in the case of enough ports, some more complex functions, such as the division of Virtual Local Area Networks (VLANs), and the like, can be theoretically realized by different port PHY state combinations.
