Switch device

Abstract

The invention discloses a switch device, and relates to the technical field of switches. The switch device comprises a configuration management module, a state retrieval module and a dynamic tree protocol module; the configuration management module is used for sending state configuration information and state retrieval information; the state retrieval module is used for broadcasting the received state retrieval information; and the dynamic tree protocol module is used for receiving the state configuration information and returning running state information to the state retrieval module according to the state retrieval information. The configuration management module sends state configuration information and state retrieval information; the dynamic tree protocol module receives the state configuration information and returns running state information to the state retrieval module according to the state retrieval information; any switch can independently run a dynamic protocol, and can also independently process and forward messages without being processed by a single special switch, so that the service load of the switch is reduced, the system cost is reduced, and the information processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of switches, in particular to a switch device. Background technique [0002] Switch stacking technology is used to expand ports on Ethernet switches. The stacking mode is determined by each manufacturer; it does not support topology and manages a group of switches as one object; the existing switch stacking is called daisy chain stacking, which is A stacking technology based on cascading structure, constructing a cascading structure of multiple switches, through loops, redundancy can be achieved to a certain extent. [0003] Existing packet processing and protocol calculation must be performed entirely on the main switch; after the switches are stacked, the number of interfaces of multiple switches is very large; the messages on these interfaces and the running MSTP protocol are all processed on the main switch, making the main switch The load is very heavy, the CPU usage is high, the failure rate is high, ...
