Fig. 1 is a schematic diagram of a method for restoring a default configuration of a device according to an embodiment of the present invention, as shown in fig. 1:
the upper computer 110 sends a connection request message to the network device 120 through s1, and after receiving and verifying the connection request message, the network device 120 sends a connection feedback message to the upper computer 110 in s 2.
The upper computer 110 receives the connection feedback message sent by the network device within the preset time interval, and then sends a reset message request message to the network device 120 through s3, the network device 120 receives the verification reset request message, and when the verification is passed, the reset feedback message is sent to the upper computer 110 in s4, and the upper computer 110 receives the reset feedback message within the preset time interval, so that the user is prompted to operate successfully, otherwise, the operation failure is prompted.
And when the upper computer 110 does not receive the connection feedback message or the reset feedback message within the preset time, exiting the current upper computer program, and controlling the upper computer to send a message to the network equipment 120 every certain time in the upper computer program for confirming whether to establish connection with the network equipment or complete reset.
The upper computer is computer equipment capable of directly sending control instructions, such as a Personal Computer (PC), a tablet Personal Computer (PC), an industrial personal computer and the like, instruction information can be sent to the lower computer through a computer program in the upper computer, and the network equipment is a physical entity connected to a network, such as a network bridge, a gateway, a router and the like, and can receive the instruction information sent by the upper computer to perform feedback and execute corresponding operations.
Referring to fig. 2, a flow chart of a method for recovering a default configuration of a device according to an embodiment of the present invention includes:
s201, an upper computer sends a connection request message to network equipment, and if the upper computer receives a connection feedback message sent by the network equipment within a first preset time interval, the upper computer sends a reset request message to the network equipment;
the upper computer can send a network request message to the network equipment every certain time (such as 5 seconds), and within a first preset time interval, if a feedback message of the network equipment is not received, the upper computer repeatedly sends the network request message, and when the first preset time interval is exceeded, the upper computer exits from the current upper computer program.
Specifically, when the upper computer does not receive a connection feedback message sent by the network device within a first preset time interval, exiting from the current upper computer program. The current upper computer program is a program for controlling the upper computer to send a connection request to the network equipment at present, and can also be a program for controlling the network equipment to reset through the upper computer.
Preferably, the network device verifies at least the ethernet type, the message length, the destination physical address, the source physical address, the message subtype and the message identifier of the connection request message.
S202, the upper computer receives the reset feedback message sent by the network equipment in a second preset time interval, and then prompts a user that the operation is successful.
And in a second preset time interval, the network equipment repeatedly sends a reset request message for sending the reset feedback message, and if the reset request message is not received after exceeding the second preset time interval, the current upper computer program is also exited.
Specifically, when the upper computer does not receive the reset feedback message sent by the network device within a second preset time interval, the upper computer prompts that the operation of the user fails.
It is noted that the first predetermined time interval and the second predetermined time interval merely represent differences in the length of the time intervals, and typically the second predetermined time interval is smaller than the first predetermined time interval.
It should be further noted that, in the network device, the message needs to be verified when the connection request message or the reset request message is received, where the message includes an ethernet type of the message, a message length, a destination physical address, a source physical address, a message subtype, a message flag, and the like. In this embodiment, in order to prevent the common packet from having the same content as the connection request packet and the reset request packet, the frame length, the ethernet type, and other fields in the upper computer are distinguished.
Specifically, in the message mutually transmitted by the upper computer and the network device, the length of the byte is set to be 88 bytes, and the first 19 bytes are filled according to a frame format, including an ethernet type, a message length, a destination physical address, a source physical address, a message subtype, a message mark and the like. Random numbers are filled in the 20-88 fields of the message.
Illustratively, the message frame format is:
when the message is verified, the method comprises the following steps:
(1)Ethertype＝0x5566；
(2) whether the length of the message is equal to 88;
(3)Dmac＝02-02-02-02-02-02；
(4) if Smac is 04-04-04-04-04;
(5)Subtype＝0x0C；
(6)Flag＝00-20-A8。
when the above conditions are simultaneously met, the message passes the verification.
By the method provided by the embodiment, the recovery of the default configuration of the equipment can be simply and quickly finished for the network equipment which cannot recover the default configuration of the equipment through hardware reset and the user forgets the user name, the password or the IP address.
