Method and device for installing hardware table items and network equipment

Abstract

The invention provides a method and device for installing hardware table items and network equipment. The method comprises the following steps of: when an installed multi-exit direction hardware table item of which a valid port has an intersection set with a valid port of a multi-exit direction hardware table item to be installed exists in a hardware table, splitting at least one of the multi-exit direction hardware table item to be installed and the installed multi-exit direction hardware table item, so that the split multi-exit direction hardware table item at least independently acts on all ports in the intersection set; and installing the multi-exit direction hardware table item to be installed in the hardware table according to the splitting result. When multi-exit direction hardware table items are installed according to the technical scheme provided by the invention, the problem that a part of the hardware table items are invalid when multiple hardware table items acting on multiple ports act on a same port at the same time can be solved so that multiple hardware table items can act on a same port at the same time.

Description

Technical field [0001] The invention relates to the field of data communication, and in particular to a method, device and network equipment for installing hardware entries. Background technique [0002] At present, the ASIC switching chip provides a hardware table for access control of messages entering and leaving the port. Among them, for the message that enters the port, the ASIC switching chip will look up the hardware table according to the information in the message (such as header fields or message content, etc.). When the query finds that there is a matching field in the hardware table that is the same as the information in the message In the hardware table entry, the port that the message enters is matched in the port bit map (Port Bit Map; referred to as PBMP) of the hardware table entry. When the port that matches the port the message enters is matched, the hardware The security rules in the entry take effect on the port where the packet enters, that is, the security...
