In the network, each network device periodically sends LLDP messages to neighbor devices. And if the local configuration of the equipment is changed, immediately sending the LLDP message. And when the device receives the LLDP message, the validity of the LLDP message is checked, and the neighbor information is updated after the LLDP message passes the validity check.
In practical application, when the network management IP address of the network equipment needs to be modified, the network management IP address of the network equipment is modified by logging in through a serial port line.
The method provided by the invention does not need to log in and modify the network management IP address of the network equipment through the serial port line, but dynamically modifies the network management IP address of the network equipment. In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In this step 101, the network device determines that the network management IP address of the peer device needs to be modified according to actual requirements, and the modified network management IP address is recorded as a second network management IP address. That is to say, when it is determined that the network management IP address of the peer device needs to be modified from the first network management IP address to the second network management IP address, the network device sends an IP address modification packet to the peer device, and the IP address modification packet sent to the peer device carries the second network management IP address.
After the peer device receives the IP address modification packet, it modifies the network management IP address of the peer device into the network management IP address specified by the received IP address modification packet, i.e. the second network management IP address, if the peer device receives the IP address modification packet in step 102, and returns an IP address modification success response packet to the source MAC address of the received IP address modification packet.
In the above description, the IP address modification packet and the IP address modification success response packet are packets defined at the link layer to implement the present application, and belong to link layer packets.
As can be seen from the flow shown in fig. 1, in the present application, network management IP addresses can be dynamically modified mutually between network devices through link layer messages.
In a disclosed embodiment, before the process shown in fig. 1, the network device may further dynamically acquire the network management IP address of the peer device, where the acquired network management IP address is the first network management IP address. In another disclosed embodiment, the network device may further pre-configure a network management IP address of the peer device, that is, the first network management IP address, and the network device may obtain the network management IP address of the peer device, that is, the first network management IP address, based on the configuration. The following only describes that the network device dynamically acquires the network management IP address of the peer device as an example.
As an embodiment, the dynamically acquiring, by the network device, the network management IP address of the peer device may include:

In a disclosed embodiment, the network device may further receive an IP address modification packet, modify the network management IP address of the network device to the network management IP address specified by the received IP address modification packet, and return an IP address modification success response packet to the source MAC address of the received IP address modification packet. As an embodiment, modifying the network management IP address of the device to the network management IP address specified by the received IP address modification packet includes:
and judging whether the network management IP address specified by the received IP address modification message meets the IP address modification condition of the equipment, if so, modifying the network management IP address of the equipment into the network management IP address specified by the received IP address modification message.

As an embodiment, in the present invention, before modifying the network management IP address of the network device to the network management IP address specified by the received IP address modification packet, the network device further includes: judging whether the state of the equipment is an IP address modification state, if not, setting the state of the equipment as the IP address modification state, and continuously executing the operation of modifying the network management IP address of the equipment into the network management IP address specified by the received IP address modification message; if yes, returning the message that the IP address is modifying to the source MAC address of the received message that the IP address is modifying.
Further, after modifying the network management IP address of the network device to the network management IP address specified by the received IP address modification packet, the network device further includes: and deleting the setting of the state of the equipment as the IP address modification state. Here, as an embodiment, the setting of the state of the device as the IP address modification state is exemplified by setting the state of the device to a first setting value such as 1. Correspondingly, the setting for deleting the state of the device into the IP address modification state is to set the state of the device to a second set value, such as 0.
Further, in a disclosed embodiment, the network device may further return to the step of sending the IP address modification packet to the peer device when waiting for more than one set listening period to arrive when receiving that the peer device is modifying the packet for the IP address returned to the device by the IP address modification packet sent by the device in the set listening period.
The method provided by the invention is described below by way of example based on the above description:
referring to fig. 2, fig. 2 is a schematic diagram of an embodiment provided in the present application. Before describing the embodiment shown in fig. 2, a structure of a packet related to this embodiment is described:
in the embodiment shown in fig. 2, all packets use Ethernet (Ethernet) II format. Fig. 3 shows a structure of an Ethernet (Ethernet) II format, mainly including:
a Destination MAC address field (Destination MAC address), a Source MAC address field (Source MAC address), a message Type field (Type), a Data field (Data) and a check Field (FCS).
The message Type field (Type) specifically indicates whether the message is a request (Req) message or a response (ACK) message, and when the message is a request message, the message Type field is a Type value used for indicating the request message, such as 1, and when the message is a response message, the message Type field is a Type value used for indicating the response message, such as 0.
Wherein, the data field mainly consists of data units (PDUs), and the PDUs consist of TLVs, and table 2 shows, by way of example, each TLV:
TABLE 2
In the embodiment shown in fig. 2, the device 1, the device 2, and the device 3 exist in the network as an example.
In fig. 2, taking the example that the device 1 dynamically acquires the network management IP addresses of the devices 2 and 3 as the opposite devices, then,
the device 1 broadcasts an IP address request message within the network. Based on the message structure shown in fig. 3, the destination MAC address field of the IP address request message is a MAC address set to indicate broadcasting, such as FFFF; the source MAC address field of the IP address request packet is the MAC address (denoted as MAC1) of the device 1, and the packet type field of the IP address request packet is a type value such as 1 used to represent the request packet; the TLV of the data field of the IP address request packet is the MAC TLV and the IPv4TLV in table 1. Specifically, the MAC TLV is a TLV corresponding to the MAC address of the device 1, and the IPv4TLV is a TLV corresponding to the network management IP address (denoted as IP1) of the device 1.
After the device 1 broadcasts the IP address request message in the network, both the devices 2 and 3 in the network receive the IP address request message broadcasted by the device 1.
When the device 2 receives the IP address request message broadcasted by the device 1, and analyzes that the MAC address carried by the received IP address request message is MAC1, an IP address response message is returned to the MAC 1. Based on the message structure shown in fig. 3, the destination MAC address field of the IP address response message is the MAC address of device 1, i.e., MAC1, the source MAC address field of the IP address response message is the MAC address of device 2 (denoted as MAC2), the message type field of the IP address response message is a type value used for indicating a response message, such as 0, and the TLV of the data field of the IP address response message is exemplified as shown in table 3.
TABLE 3
In this embodiment, the IP address response packet returned by the Device 2 carries a Device Type TLV and a Device SN TLV, which is convenient for the Device 1 to determine to which Device the network management IP address of the Device 2 carried in the received IP address response packet corresponds.
When the device 3 receives the IP address request message broadcast by the device 1, and analyzes that the MAC address carried in the received IP address request message is MAC1, an IP address response message is returned to the MAC 1. Based on the message structure shown in fig. 3, the destination MAC address field of the IP address response message is the MAC address of the device 1, i.e., MAC1, the source MAC address field of the IP address response message is the MAC address of the device 3 (denoted as MAC3), the message type field of the IP address response message is a type value used for indicating a response message, such as 0, and the TLV of the data field of the IP address response message is exemplified as shown in table 4.
TABLE 4
In this embodiment, the IP address response packet returned by the Device 3 carries a Device Type TLV and a Device SN TLV, which is convenient for the Device 1 to determine to which Device the network management IP address of the Device 3 carried in the received IP address response packet corresponds. .
The device 1 monitors an IP address response message in a set request period after broadcasting the IP address request message, where the set request period is configured in advance.
When the device 1 monitors the IP address response packet from the device 2 in the set request period, the IP address response packet is analyzed to obtain the network management IP address of the device 2 carried by the IP address response packet. Similarly, when the device 1 monitors the IP address response packet from the device 3 in the set request period, the IP address response packet is analyzed to obtain the network management IP address of the device 3 carried in the IP address response packet.
It should be noted that, after the set request period is ended, if the device 1 monitors the IP address response packet from the device 2 or the device 3, the monitored IP address response packet is discarded. It should be further noted that, based on the asynchronous communication between the sending of the IP address request packet and the sending of the IP address response packet, the device 1 may monitor multiple IP address response packets returned by the same device, such as the device 2, in a set request period, and for this situation, the device 1 may perform repeated packet filtering according to the source MAC address, which is similar to the existing repeated packet filtering and is not described again.
The above description has been made on the device 1 dynamically acquiring the network management IP addresses of the device 2 and the device 3.
After acquiring the network management IP address of the device 2 and the network management IP address of the device 3, the device 1 finds that the device types and the device serial numbers of the device 2 and the device 3 are different, but the network management IP addresses are the same and are both IP 2. For this case, the device 1 determines to modify the network management IP address of the device 3. It should be noted that this case is only one embodiment in which the device 1 determines to modify the network management IP address of the device 3, and other cases, such as adjusting the network management IP address of the device 3 based on the service plan of the device 3, or modifying the network management IP address of the device 3 based on the user configuration, etc., are not specifically limited in this embodiment.
Suppose the modified network management IP address of the device 3 is IP 3. The IP3 is different from the IP1, which is the network management IP address of the device 1, and the network management IP address of any other device acquired by the device 1. As one embodiment, the network segment to which IP3 belongs is the same as the network segment to which device 1's administrative IP address, IP1, belongs.
Device 1 sends an IP address modification message to device 3. Based on the message structure shown in fig. 3, the destination MAC address field of the IP address modification message is the MAC address of the device 3, i.e., MAC3, the source MAC address field of the IP address modification message is the MAC address of the device 1, i.e., MAC1, the message type field of the IP address modification message is a type value for indicating a request message, such as 1, and TLVs of the data field of the IP address modification message are exemplified as shown in table 5.
TABLE 5
The device 3 receives the IP address modification message sent by the device 1 and judges whether the state of the device is the IP address modification state or not;
if the device 3 judges that the state of the device is not the IP address modification state, the state of the device 3 is set to be the IP address modification state; then, the device 3 determines whether the IP3 carried in the IP address modification message satisfies the IP address modification condition of the device 3. The IP address modification conditions here are, for example: the network segment to which the IP3 belongs is the same as the current network management IP address of the device 3, that is, the network segment to which the IP2 belongs. When the device 3 determines that the IP3 carried in the IP address modification packet satisfies the IP address modification condition of the device 3, the network management IP address of the device 3 is modified to IP3, the setting that the state of the device is the IP address modification state is deleted, for example, the state of the device is updated from the IP address modification state to the non-IP address modification state, and then a response packet indicating that the IP address modification is successful is returned to the device 1. Based on the message structure shown in fig. 3, the destination MAC address field of the successful response message for IP address modification is the MAC address of device 1, i.e., MAC1, the source MAC address field of the successful response message for IP address modification is the MAC address of device 3, i.e., MAC3, the message type field of the successful response message for IP address modification is the type value used for indicating the response message, e.g., 0, and an example TLV of the data field of the successful response message for IP address modification is shown in table 6.
TABLE 6
As an embodiment, when the device 3 determines that the IP3 carried in the IP address modification message does not satisfy the IP address modification condition of the device 3, the device deletes the setting that the state of the device is the IP address modification state, for example, updates the state of the device from the IP address modification state to the non-IP address modification state, and then returns an IP address modification failure response message to the device 1. Based on the message structure shown in fig. 3, the destination MAC address field of the IP address modification failure response message is the MAC address of the device 1, i.e., MAC1, the source MAC address field of the IP address modification failure response message is the MAC address of the device 3, i.e., MAC3, the message type field of the IP address modification failure response message is a type value used for indicating a response message, e.g., 0, and TLV of the data field of the IP address modification failure response message is exemplified as shown in table 7.
TABLE 7
When the device 3 judges that the state of the device is the IP address modification state, the device 3 returns a message that the IP address is being modified to the device 1. Based on the message structure shown in fig. 3, the destination MAC address field of the message being modified by the IP address is the MAC address of device 1, i.e., MAC1, the source MAC address field of the message being modified by the IP address is the MAC address of device 3, i.e., MAC3, the message type field of the message being modified by the IP address is a type value for indicating a response message, e.g., 0, and TLV of the data field of the message being modified by the IP address is exemplified as shown in table 8.
TABLE 8
The device 1 monitors the message returned by the device 3 in the set monitoring period, wherein when the device 1 monitors the IP address modification success response message sent by the device 3 in the set monitoring period, it is determined that the device 3 has successfully modified the network management IP address from IP2 to IP 3. When the device 1 does not monitor any message returned to the device by the device 3 for the IP address modification message in the set monitoring period, the step of sending the IP address modification message to the opposite terminal device is continued. When the device 1 receives the message that the device 3 returns to the device for modifying the IP address in the set monitoring period, the device 1 returns to the step of sending the IP address modification message to the opposite terminal device when waiting for more than one set monitoring period. And when the device 1 monitors the IP address modification failure response message sent by the device 3 in the set monitoring period, it determines a new modified network management IP address for the device 3 again, and records the new modified network management IP address as IP4, and executes the operation of sending the IP address modification message to the device 3 according to the above-mentioned description, which is not repeated.
