Abstract

The application provides a method and device for obtaining interface packet loss messages, which are applied to network security equipment. The above network security equipment includes several service boards; the above service boards are connected through cascading interfaces; the above network security equipment maintains the above service The connection relationship between the boards; the method includes determining whether there is a packet loss interface in the above-mentioned cascade interface; if there is a packet loss interface in the above-mentioned cascade interface, determine the above-mentioned packet loss interface as the packet receiving interface based on the connection relationship between the above-mentioned service boards match the destination interface in the packet received by the above packet loss interface with the above outbound interface, and use the packet whose destination interface in the above packet does not match the outbound interface of the above device as a packet loss packet to store.

Description

Technical field [0001] The present application relates to the field of computer technology, and more particularly to a method and apparatus for acquiring interface packet loss. Background technique [0002] Currently, network security equipment typically uses the structure of a number of service boards in the main control board. Users can configure different functional service boards based on demand, reducing the complexity of business deployment, reducing hardware costs. [0003] In the above structure, the main control board can be connected to the service board through a high speed channel; each service board can be connected by a cascading interface. When the packet is entered from the interface, and when the target service board (the inner interface is not belongs to the target service board), the main control board can transmit the above-described packet through the above-described tibble to the target service board. When the above-described message is processed by the targ...
