Embodiment 1
[0060] The interface topology control method in the communication device provided by Embodiment 1 of the present invention specifically describes the implementation process of the interface topology control on the main control card, and its flow is as follows Figure 4 shown, including the following steps:
[0061] Step S101: The main control card is started, and an interface table of the main control card is created.
[0062] After the main control card is started, it completes the creation of the main control card interface table maintained by itself, and prepares to receive the synchronization signal sent by the line card to synchronize the interface information of the line card.
[0063] Step S102: the main control card assigns a global identifier to its own main control card interface, and writes its own main control card interface information and the assigned global identifier into the main control card interface table.
[0064] When the main control card writes its own...
Embodiment 2
[0083] The interface topology control method in the communication device provided by the second embodiment of the present invention specifically describes the implementation process of the interface topology control on the line card, and its flow is as follows Figure 5 shown, including the following steps:
[0084] Step S201: the line card is started, and a line card interface table is created.
[0085] After the line card is started, it completes the creation of the line card interface table maintained by itself, and prepares to receive the synchronization signal sent by the main control card to synchronize the interface information of the main control card and the interface information of the line card.
[0086] Step S202: the line card assigns a local identifier to its own line card interface, and writes its own line card interface information into the line card interface table.
[0087] When the line card writes its own line card interface information into the line card ...

Abstract
The invention discloses an interface topology control method, an interface topology control system and an interface topology control device for communication equipment. The method comprises that: when receiving line card interface information from line cards, a master control card allocates global identifiers to line card interfaces corresponding to the received line card interface information, and adds the received line card interface information and the corresponding global identifiers into a pre-established master control card interface table; the master control card synchronizes the received line card interface information and the corresponding global identifiers to all the line cards in the communication equipment; and when receiving the line card interface information and the corresponding global identifiers synchronized by the master control card, the line cards update local line card interface tables according to the received line card interface information and the corresponding global identifiers. In the method, the system and the device, the interface information between the master control card and the line cards is maintained and synchronized by the interface tables, interface topology management control is realized conveniently and highly efficiently, and the reliability of the communication equipment is improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to an interface topology control method, system and device in communication equipment. Background technique [0002] Communication devices in the network include routers, switches, bridges, firewalls, etc., for example: figure 1 Shown is a schematic diagram of the architecture composition of the existing network equipment. The network equipment includes a backplane installed in the chassis, a main control card and a service board that can be plugged into the backplane. The service board can include multiple, such as figure 1 The service board A and service board B are shown. The structure of the service board is as follows: figure 2 As shown, multiple line cards can be inserted into each service board, so there can be multiple interfaces. [0003] Since the communication equipment needs to be connected with various communication equipment, its interfaces must also be varie...
