Embodiment Construction

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

Abstract

The invention discloses a port mirroring realization method and device based on network equipment. The method comprises the following steps: acquiring a port mirroring source port and a port mirroring target port of the network equipment; determining whether a first switch card corresponding to the port mirroring source port of the network equipment is same as a second switch card corresponding to the port mirroring target port of the network equipment according to a port and switch card mapping table; if the first switch card is different from the second switch card, determining a cascading switch card between the first switch card and the second switch card according to the port and switch card mapping table; configuring the port mirroring source port and the port mirroring target port of each of the first switch card, the second switch card and the cascading switch card. A port mirroring function crossing the switch cards can be realized by use of the scheme disclosed by the invention.

Description

Technical field [0001] The invention relates to the field of communication technology, 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 the message of 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 Local Switched Port Analyzer (SPANRSPAN), is an extension of port mirroring. Remote port mirroring breaks through the restriction that the source port and the destination port must be on the same network device, making the source port and the destination port It can span multiple network devices, and the user can observe the data packets of the remote mirror port through the analyzer in the central computer room. [0004] At present, the multi-switch card cascading design used to exp...
