Embodiment Construction

[0050]Aiming at the problems existing in the prior art that the port mirroring function across switch cards cannot be realized in the network equipment, which affects the network monitoring of the network equipment during operation and troubleshooting after a failure occurs, the embodiment of the present invention provides a network equipment based In the port mirroring implementation method, the network device includes at least three switching cards. It should be noted that network equipment can be divided into distributed network equipment and centralized network equipment. Since at least three switch cards in the network equipment in the embodiment of the present invention are connected in cascaded form, at least three switch cards are included. The network equipment of the card is a centralized network equipment. The procedure of this method is as follows figure 1 As shown, the execution steps are as follows:

Abstract

The invention discloses a method and device for implementing port mirroring based on network equipment. The method includes: acquiring the port mirroring source port and the port mirroring destination port of the network device; Whether the first switch card to which the port mirroring source port belongs is the same as the second switch card to which the port mirroring destination port of the network device belongs; if the first switch card is different from the second switch card, then according to the port and the switch card mapping table to determine the cascaded switch card between the first switch card and the second switch card; configure the ports of the first switch card, the second switch card, and the cascaded switch card Mirror source port and port mirror destination port. This solution can realize the port mirroring function across switching cards.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for implementing port mirroring based on network equipment. Background technique [0002] Port mirroring, also known as Local Switched Port Analyzer (SPAN), users can use this function to copy packets from a specified port to another local port connected to a network monitoring device for network monitoring and troubleshooting. [0003] Remote port mirroring, also known as remote (Remote Local Switched Port Analyzer, SPANRSPAN), is an extension of port mirroring. Remote port mirroring breaks through the restriction that the source port and destination port must be on the same network device, making the source port and destination port It can span multiple network devices, and users can observe the data packets of the remote mirror port through the analyzer in the central computer room. [0004] At present, in order to expand the port capacity of network...
