Abstract
The invention discloses an address resolution protocol configuration method and device for a network management system. The method comprises the following steps: determining a first physical port from member ports contained in a three-layer interface A, recording a first parameter corresponding to the first physical port, acquiring link data through which a first network element is connected with a second network element to generate a corresponding link data parameter, finding out the second parameter of a second physical port butted with the first physical port in the second network element according to the link data parameter and the first parameter, judging whether the second physical port corresponds to a three-layer interface B in the second network element, if so, then acquiring the MAC address of the three-layer interface B according to the second parameter, and creating and saving an ARP (address resolution protocol) clause according to the IP address of the second network element and the MAC address. Through the adoption of the method and the device, provided by the invention, the efficiency of configuring the ARP clause of a user is improved, the error probability caused by manual configuration by a webmaster is effectively eliminated, and the usability of the network management system is improved.
Description
Technical field
The invention belongs to network communications technology field, relate in particular to address resolution protocol collocation method and device under a kind of network management system.
Background technology
When a network equipment sends data to another network equipment, except knowing the IP address of object equipment, also to know the physical address (MAC Address) of object equipment.ARP(Address Resolution Protocol) effect is mapped to physical address by IP address exactly, to guarantee carrying out smoothly of communication.
First source device broadcast is with the ARP request of object IP address of equipment, and all devices on this network all can be received this ARP request.If mate with oneself the IP address in a device discovery request, to source device, send one and comprise replying of MAC Address.Source device replys by this MAC Address that obtains object equipment.
In order to reduce the ARP bag on network, and send faster data, the mapping relations of IP address and MAC Address (arp entry) are buffered in local ARP table.When equipment need to send data, first according to IP address search ARP table, if find the MAC Address of object equipment in ARP table, just do not need to send again ARP request
In present webmaster, three layer interfaces can create based on a variety of logic interfacing or physical port, the arp entry that relies on three layer interfaces of every kind of logic interfacing or physical port establishment can not be asked automatically to generate by dependence equipment transmission ARP again, so need manual configuration.During manual configuration arp entry, because of the difference of the port based on creating, collocation method is also different.Manual configuration process is extremely complicated, configures searching of physical port that an arp entry not only related to opposite equip., three layer interfaces, but also related to the whether same network segment of IP, MAC calculates scheduling algorithm.If unskilled user, in operating process, very easily there is mistake, and investigate while locating and also quite waste time and energy afterwards, even skilled user, there is the phenomenon of inefficient operation in capital, therefore, and for various three layer interfaces, develop a kind of employing button and trigger, the method for automatically calculating arp entry seems particularly important.
