Problems solved by technology

[0008] For multi-board communication equipment, if multiple management control ports are set, the cost and space will increase; if one management control port is set, the network address cannot be obtained for the board module without the management control port, which increases the burden of multi-board address management. difficulty

Embodiment Construction

[0025] Figure 1 is a schematic diagram of multi-board communication equipment; the switching chip on the switching board is connected to the CPU on other boards, the switching chip is connected to the service interface, and the CPU of the other board is connected to the service interface. Other boards can be one or more boards, and can be switching boards or serial port boards.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] In this embodiment, a multi-board communication device composed of a serial port server board and an Ethernet switching board is taken as an example, and the IP address and MAC address of the serial port server are sent to the management CPU of the switching board. Obtain the management address of the serial server.

[0028] Figure 2 indicates a multi-board communication device; the multi-board is composed of a serial server part and an Ethernet switching part;...

Abstract

The invention discloses a multi-board communications equipment address query method, the key points of the technical scheme are as follows: comprising at least board modules and querying the address information of another board module or several board modules by an LLDP protocol, which are that: A1. a board module needing to query sends an LLDP message to an MAC address, and repeatedly sends the message at interval: A2. a receiving board module manages a CPU to receive the LLDP message, and upgrades and storage the message in real time; and A3. when needing to query the board module to log in, a user is free from remembering the address of the board module needing to query, the log can be realized by the address stored in the interior of a system. The invention has the purposes that by the invention, the user can obtain the management address of another board through a board CPU, the problem that a network address can not obtained when other boards have no debug serial port can be solved, the difficulty of the multi-bard address management can be reduced, the cooperation capability of the system can be improved, and the use is very convenient.

Description

technical field [0001] The invention relates to the field of communication, more specifically, to an address query method between boards in the field of Ethernet communication, the field of serial port communication, and the field of conversion and transmission between serial port and Ethernet. Background technique [0002] Link Layer Discovery Protocol (Link Layer Discovery Protocol, LLDP) is a new protocol defined in 802.1ab, which enables neighboring devices to notify other devices of their status information, and each port of all devices stores a definition of their own If necessary, they can also send updated information to their directly connected neighbors. The neighbors will store the information in standard SNMP MIBs. The network management system can query the current connection status of the second layer from the MIB. LLDP neither configures nor controls network elements or traffic, it just reports the Layer 2 configuration. Another content in 802.1ab is to make...
