Problems solved by technology

[0012] Considering that the SVLAN configuration information is stored on both the main control board and the line card, when the configuration information on the main control board changes, the main control board needs to synchronize all its own configuration information to the line card. is very inefficient
The information transmission mode between the main control board and the line card is asynchronous. Due to the limitation of the size of the asynchronous message capacity and the limitation of the timer, when the data that needs configuration information is large, it is necessary to divide the configuration information into multiple groups. Make sure that every time the synchronization is successful, it can only be synchronized in place after several consecutive cycles. When the synchronization of a certain group fails, it needs to be re-synchronized from the first group. It is conceivable that there are many redundant and cumbersome operation, which will inevitably lead to low configuration efficiency

Abstract

The invention discloses a configuring method of a stacking virtual local area network (SVLAN) of a distributed network device. By adopting a unique synchronization technology, the synchronous process of the SVLAN service based on an access control list (ACL) is realized both in the aspect of responding user instruction configuration and parameter analysis by a master control board and in the aspect of transmitting the configuration information from the master control board to each service board on the distributed network device, configuration release and function validation of each service board are realized, conventional configuration and processing flow are improved, and system resources are optimized, thereby improving operation efficiency and reliability of the system. The invention also discloses a configuring device of the SVLAN of the distributed network device. The invention has simple realization and strong practicability.

Description

technical field [0001] The present invention relates to a configuration technology of a stack virtual local area network (SVLAN, Stack Virtual Local Area Network), in particular to a method and a device for configuring a stack virtual local area network in a distributed network (Distributed Network) device. Background technique [0002] SVLAN is a virtual local area network (VLAN, Virtual Local Area Network) tunneling technology. On the basis of the existing VLAN tag (802.1Q tag protocol), an outer VLAN tag is encapsulated to shield the inner VLAN tag. . The inner VLAN tag identifies the network attributes on the user side, and the outer VLAN tag is provided to the network service provider for deployment. In this way, the inner VLAN tag and other contents of the message are transparently transmitted through the network of the network service provider. The user provides a relatively simple Layer 2 tunnel transmission method. [0003] Access Control List (ACL, Access Contro...
