Embodiment 1

[0025] Example one, reference Figure 4 Shown: Configure a cross-board LinkAgg service. The Member Ports of LinkAgg are Port7 of line card 1 and Port13 of line card 2. In this scenario, line card 1 is required to configure Port7 (LPP7) and LPP13 as an AGG Group At the same time, Port7 (LPP7) and LPP13 of line card 2 must be configured as an AGG Group.

[0026] If there is a LinkAgg for line cards on line card one and line card two, for example, Port3 and Port13 are a LinkAgg, you need to do the same AGG configuration for line card 1 and line card 2 at the same time, when one of the Member LinkDown, PHY or MAC will Report the interrupt, tell the CPU port LinkDown, the CPU removes the LinkDown member of the AGG Group from the AGG Group.

[0027] The present invention redefines the port mapping relationship of the dual-line card backup, and the present invention reduces the software maintenance cost of the dual-line card backup by configuring the chip of the line card.

Abstract

The invention provides a double-line-card mutual backup configuration method, which comprises a line card 1 and a line card 2. A software development kit runs on the line card 1 and the line card 2. The line card 1 and the line card 2 serve as backups for each other. Correspondence relations of ports of the line card 1 and the line card 2 and high-speed data ports are different. The line card 1 and the line card 2 have an independent data path each. When a message needs to be sent out of a chip, no matter the line card is a master card or a backup card, 16 ports need corresponding external interfaces LPP1-LPP16 in outlet direction in the chip, and actual queue forwarding can be realized; when the line card is a backup card, the 16 ports needs to map 16 extra local physical interfaces LPP 17-32 in the outlet direction, and transparent message transmission is realized; and when the line card is a master card, the 16 ports do not need to map extra local physical interfaces in the outlet direction. Through configuration of the line card chip, double-line-card backup software maintenance cost can be reduced.

Description

Technical field [0001] The invention relates to the technical field of Ethernet, in particular to a configuration method and configuration device for dual-line card intercommunication backup. Background technique [0002] As the core component of the network, the switch must ensure the normal operation of the equipment whether it is the core network layer, the aggregation layer or the access layer. In order to improve the reliability of the network, a variety of active and standby protection schemes are now proposed, but they are basically all There are two approaches. One is to increase the switch to realize the backup of the switch. The other is the backup of the switch itself through multi-power supply and multi-line cards. The above two methods greatly increase the software maintenance cost. Summary of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a dual-line card interworking backup configuration method, w...
