Embodiment Construction

[0069] At first the technical terms involved in the present invention are described as follows:

[0070] Ctmark and VLID respectively refer to the upper 4-byte field and the lower 2-byte field of the destination MAC address of the Ethernet frame, see Figure 4 .

[0071] Communication port: refers to the port where the switch performs normal routing and switching.

[0072] Monitoring port: Refers to the port specially used to monitor the message frame of the communication port.

[0073] The multi-monitoring port method of the switch based on VLID monitoring provided in this embodiment, its overall logical block diagram is as follows figure 1 As shown; among them, MAC_1~MAC_M are communication port 1 to communication port M, and Monitor_MAC_1~Monitor_MAC_N monitor port 1 to monitor port N. In order to facilitate the description, the value of N is taken as 4, and the logical block diagram of M communication ports and 4 monitoring ports is used as an example to explain (see ...

Abstract

The invention discloses a switch multi-monitoring-port method based on VLID monitoring, and the method specifically comprises the following steps: 1, building a communication port cache, building a monitoring lookup table, building a monitoring port cache, and configuring a CT flag register according to a communication port; 2, setting a corresponding frame filtering module at each communication port; step 3, reading out and writing the message frame stored in each communication port cache into a monitoring port cache corresponding to the communication port cache; and 4, each monitoring port corresponds to M monitoring port caches, and when the message frames are partially or completely stored in the M monitoring port caches, the stored message frames are read through algorithm polling and then sent to the monitoring ports. According to the method disclosed by the invention, the message quantity, the coverage degree, the accuracy and the time sequence of monitoring are greatly improved.

Description

technical field [0001] The invention belongs to the field of computer networks, and in particular relates to a method for monitoring multiple monitoring ports of a switch based on VLID monitoring. Background technique [0002] The switch in the computer network is a very important part of the network structure. At present, the monitoring of ordinary Ethernet switches has only one monitoring port, and a communication port is temporarily set as the monitoring port, and only the designated single communication port can be monitored. Receive or send messages for monitoring, and without any filtering and filtering functions, it is impossible to monitor the input frames containing specified fields for all communication ports, and it is also impossible to prioritize the monitored message frames. The frame content received by the communication port is the same as There is a large delay in the frame content output by the monitoring port. Therefore, most of the monitoring technologie...
