Embodiment 1
[0095] In this embodiment, the agent device adopts the first method to acquire information about address changes, that is, when a device with a dynamic address changes in address, the device notifies the agent device of information about address changes.
[0096] Figure 5 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 1 of the present invention. Such as Figure 5 As shown, the method includes:
[0097] Step 501, pre-setting a device identifier for a device with a dynamic address.
[0098] In this step, the device identifier set for the device with a dynamic address is a unique fixed identifier on the entire network within the management life cycle, which can be specifically: the host name of the device, the domain name assigned to the device by DNS, the MAC address corresponding to the management address, The lowest sorted MAC address or newly defined identification information on the device.
[0099] Assuming that the address...
Embodiment 2
[0133] In this embodiment, the second approach is adopted to acquire information related to address changes, that is, when the DHCP server allocates an address for a device with a dynamic address, it sends the allocated address information to the agent device.
[0134] Figure 8 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 2 of the present invention. Such as Figure 8 As shown, the method includes:
[0135] Step 801, pre-setting a device identifier for a device with a dynamic address.
[0136] This step is the same as step 501 in the first embodiment, and will not be repeated here.
[0137] Assume that the original IP address of device A with a dynamic address is IP1, and the DHCP server reassigns IP address IP2 to device A, and the identifier of the device with a dynamic address is ID1, then perform the following steps:
[0138] In step 802, the DHCP server sends the device identifier and the assigned address of the dynamic ...
Embodiment 3
[0176] In this embodiment, the agent device adopts a third way to obtain information about address changes, that is, the agent device actively inquires about address changes of the dynamic address device.
[0177] Figure 11 It is a specific flow chart of the method for managing dynamic address devices in Embodiment 3 of the present invention. Such as Figure 11 As shown, the method includes:
[0178] Step 1101, pre-setting an identifier for a dynamic address device.
[0179] This step is the same as step 501 in the first embodiment, and will not be repeated here.
[0180] Assuming that the address of the dynamic address device A changes, its IP address changes from the original IP1 to IP2, and the identifier of the dynamic address device is ID1, then perform the following steps:
[0181] In step 1102, the agent device actively detects whether the device identifiers corresponding to the stored IP addresses have changed, and if there is a change, execute step 1103; otherwis...
