The present invention provides a port mirroring method and device of an OLT device, wherein the method part includes: determining the target VLAN, the target VLAN is a VLAN not occupied by other services; Or the data flow on the incoming direction is copied, obtains the data packet of mirror image, adds described VLAN as outer layer label for the data packet of described mirror image; Control board according to the outer layer label of the data packet of described mirror image, The data packets are redirected to the specified monitoring port. The invention can perform single-port mirroring, and has positive effects of cost saving and accuracy.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a port mirroring method and device of an OLT device. Background technique [0002] Port mirroring is a must-have feature for most routers, switches, and OLT (optical line terminal) equipment. Especially in scenarios with high data security requirements, it is required to use the port mirroring function to monitor equipment access and exit. Direction data real-time monitoring. [0003] For OLT access network equipment, it is not only required to monitor the incoming and outgoing direction of the equipment, but also needs to monitor the incoming and outgoing direction data of a single PON port in specific camera monitoring and other occasions. [0004] In the prior art, with the development of PON technology and the improvement of integration, the PON single-board port and the uplink single-board mirroring port of the OLT large-scale equipment are not on the same bo...
