Problems solved by technology

When adding 2 service boards (that is, there are 4 service boards in total), the size of the ARP table that the main control card needs to issue is 256K. If one service board cannot meet the 256K capacity of the ARP table, it will As a result, the delivery of the ARP table fails, and Layer 3 services cannot be forwarded; at this time, the service boards that cannot meet the capacity of the ARP table need to be upgraded

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0046] see figure 1 and figure 2 As shown, the ARP table configuration method of the service board in the embodiment of the present invention, all the service boards that need to be used in the method are interconnected by the switch of the FULL MESH architecture, and the method includes the following steps:

[0047] S1: Initialize (clear) the ARP data of all service boards that need to be used, so as to ensure the normal learning of subsequent new ARP tables, and turn to S2.

[0048] S2: The main control card configures the working mode for each service board that needs to be used. The working mode includes NNI (network side) and UNI (user side), that is, all business boards that need to be used can be divided into two categories according to the working mode : NNI service board (hereinafter referred to as NNI board) or UNI service board (...

Abstract

The invention discloses an ARP table configuration method and system of a service board, and relates to the field of ARP configuration. The steps of the method include: the main control card divides all the service boards that need to be used into NNI boards or UNI boards, and configures the NNI ARP table corresponding to each NNI board, and the NNI ARP table corresponding to each UNI board. UNI ARP table; the main control card sends the corresponding NNI ARP table to each NNI board, and sends the corresponding UNI ARP table to each UNI board. Both the NNI board and the UNI board are created according to the received ARP table. Local ARP hardware table. The invention can significantly reduce the capacity of the ARP table on the service board, and further greatly improve the use bottleneck of the service board without increasing the use cost of the service board.

Description

technical field [0001] The invention relates to the field of ARP (Address Resolution Protocol, Address Resolution Protocol) configuration, in particular to a method and system for configuring an ARP table of a service board. Background technique [0002] With the maturity of 40G and 100G Ethernet technologies, high-performance FULL MESH (full mesh) architecture three-layer switches have also developed rapidly. Compared with the traditional distributed three-layer switch, the switch of the FULL MESH architecture breaks through the limitation that the service board must be connected through the switching board, and realizes the distribution of data packets at low cost through the interconnection of multiple business boards. Forwarding enables switches with this architecture to have more service ports, and can be widely used in small and medium-sized data switching networks. [0003] The traditional FULL MESH architecture switch configures the ARP table working mechanism as fo...
