Problems solved by technology

[0006] However, the above-mentioned scheme of assigning a dedicated register to each service board in the logic of the main control board to store the port status information reported by the service board has a very large occupancy rate of the logic resources of the main control board.
And when there are more service slots and service board ports, the problem is more obvious

Embodiment Construction

[0030] In the prior art, in order to realize the RRPP function, a dedicated register is allocated to each service board in the main control board logic to save the port status reported by the service board, so that the number of service boards in the system and each service board The more ports there are, the more logic resources on the main control board are occupied to implement the RRPP function. To solve this problem, the main idea of ​​the present invention is: set a shared register in the main control board, and let all service boards dynamically occupy the shared register in time division. In this way, there is no need to allocate a dedicated register for each service board in the main control board, thereby greatly reducing the occupation of logic resources of the main control board.

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to ...

Abstract

The present invention discloses an interrupting report method which includes: every service plate reports self terminal port status messages to master control board when self terminal port condition changes; the main control logical of master control board enquires the each service plate, judging whether or not the service plate has terminal port status messages reporting, if service plate has, then receiving the reporting terminal port status messages, and storing identification information of present service plate and received terminal port status messages in communion register of master control board, reporting middle break to CPU of master control board. The present invention also discloses a network appliance. Technical project of the invention can save logical resource of network appliance master control board when implementing middle break reporting function.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an interrupt reporting method and a network device. Background technique [0002] The Rapid Ring Protection Protocol (RRPP, Rapid Ring Protection Protocol) is a link layer protocol specially applied to the Ethernet ring. The RRPP protocol can prevent the broadcast storm caused by the data loop when the Ethernet ring is complete, and can quickly restore the communication path between the nodes on the ring network when a link on the Ethernet ring is disconnected. [0003] In order to realize the above functions of the RRPP protocol, it is necessary to quickly know which links on the Ethernet ring are disconnected or restored in the network system. In particular, in order to meet the needs of quickly restoring the communication path between the nodes on the ring network when a link on the Ethernet ring is disconnected, the network device is required to complete the de...
