example 1
[0070] Example 1, the proxy device forwards packets from device H to device A, including:
[0071] Step 1, start;
[0072] Step 2, device H sends an ARP request, and the destination IP is device A;
[0073] Step 3: After receiving the ARP request, the proxy device C performs ARP proxy, and returns the MAC of the interface n to the device H;
[0074] Step 4, device H learns the ARP entry of device A, encapsulates the MAC of interface n as the destination MAC and sends the IP packet;
[0075] Step 5: After receiving the IP packet, the proxy device C finds that the outgoing interface is m, and after learning the ARP entry of A normally, forwards the IP packet;
[0076] Step 6, device A receives the IP packet;
[0077] Step 7, end.
example 2
[0078] Example 2, the proxy device forwards packets from device A to device H, including:
[0079] Step 1, start;
[0080] Step 2, device A searches for routes; that is, device A searches for a static route with destination IP h, the outgoing interface is a, and the next one is the IP address of m;
[0081] Step 3, after device A normally learns the ARP entry of m, it sends an IP packet;
[0082] Step 4, after proxy device C learns the ARP entry of h, it forwards the IP message;
[0083] Step 5, device H receives the IP packet;
[0084] Step 6, end.
[0085] To sum up, in this embodiment, by enabling ARP proxy on the layer 3 interface n of device C, the packets sent by interface h whose destination IP is the IP address of device A or B are all sent to the layer 3 interface of device C n, and then forwarded through the layer-3 interface m of device C; by configuring network segment routing on devices A and B, the packets sent to the layer-3 interface h of device H of the ot...

Abstract
The invention discloses a management method of a management plane of ethernet equipment and a system thereof. The method comprises: proxy equipment is selected in new access network equipment as well as a Cm interface where the proxy equipment is connected with other new access network equipment and a Cn interface where the proxy equipment is connected with webmaster access equipment are set; in an adjacent network segment of an IP address of the webmaster access equipment, a mask bit is set so as to configure IP addresses for all the new access network equipment, so that the IP addresses the Cm interface and other new access network equipment are in a sub network segment, the IP address of the Cn interface is the other sub network segment and a broadcast address of the Cn interface is the same as that of the webmaster access equipment; an address parsing protocol ARP proxy is launched at the Cn interface; and when message interaction between the webmaster access equipment and all the new access network equipment is carried out, the proxy equipment carries out message forwarding or message processing according to a destination IP address of the message. According to the invention, problems that security of a traditional networking mode is poor and responsibility is not easy to be defined and the like are solved.
Description
technical field [0001] The invention relates to the technical field of data communication, in particular to a management method and system for an Ethernet device management plane. Background technique [0002] The data communication network can be divided into three planes according to the system structure: transmission plane, control plane, and management plane. The management plane mainly provides management functions for the transmission plane, control plane and the whole system, and is responsible for the coordination and cooperation among all planes. The main functions include performance management, fault management, configuration management, billing management and security management. The security of the management plane is the key to ensuring network stability, and how to ensure the security of the management plane has become a focus of network equipment providers. [0003] The new network equipment is connected to the existing network, and the existing network use...
