Embodiment Construction
[0037] While the invention may be embodied in various forms, some exemplary and non-limiting embodiments are shown in the drawings and will be described below, it should be understood that the disclosure is to be considered as an example of the invention and not It is intended that the invention be limited to the specific embodiments described.
[0038] figure 1 A schematic block diagram of an embodiment of a method for configuring a forwarding table of a data center switch according to the present invention is shown. in such as figure 1 In the illustrated embodiment, the method at least includes the following steps:
[0039] S1: Monitor the DHCP response message transmitted on the link in real time, and copy the detected DHCP response message and its interface information to the buffer area;
[0040] S2: Extract the DHCP response message in the cache area, and parse the DHCP response message to obtain the IP address;
[0041] S3: Send a Ping to the IP address, and monitor...

The present invention relates to a configuration method and device for a forwarding table of a data center switch, wherein the method includes executing based on the data center switch: monitoring the DHCP response message transmitted on the link in real time, and combining the detected DHCP response message and its Copy the interface information to the buffer area; extract the DHCP response message in the buffer area, and parse the DHCP response message to obtain the IP address; send a Ping to the IP address, and monitor the feedback of the IP address to the Ping; respond to the detected IP address pair Ping feedback, extract the corresponding interface information in the cache area, and record the IP address and the extracted interface information in the forwarding table item. Utilizing the embodiment of the present invention improves the utilization efficiency of the network, expands the sources of forwarding entries, improves the flexibility and accuracy of forwarding entry generation, and the entire operation is automatically completed without manual intervention, and the added ping is connected at the same time. The security detection can obtain the first-hand information in the network environment in time, which improves the reliability and timeliness of the added forwarding entries.
Description
technical field [0001] The invention relates to the technical field of switches. The present invention further relates to a configuration method and device for a data center switch forwarding table. Background technique [0002] Currently, the forwarding table entries of data center switches mainly come from manual configuration of static addresses and common dynamic forwarding table protocols. Data center switches can perform routing and forwarding according to configuration or generated forwarding table entries. However, there are still some deficiencies in the above static or dynamic configuration methods, for example, the flexibility of the static configuration is poor, while the accuracy of the dynamic configuration is not high enough due to the use of second-hand information and the like. [0003] In addition, in practical applications, data center switches often need to provide DHCP relay services for DHCP servers and clients that are not on the same network segment...
