Embodiment Construction

[0024] Aiming at the problems existing in the prior art, an embodiment of the present invention provides a PSE port protection method, which is applied to a PoE system including a PSE and a PD. by figure 2 It is a schematic diagram of the application scenario of the embodiment of the present invention. The P1 port of the PSE is an uplink port, and the P1 port is connected to a data server. The data server is the object of communication with the PD. For example, when the PD is a network security camera, the data server can be The video server, when the PD is an IP phone, the data server may be a SIP (Session Initiation Protocol, Session Initiation Protocol) server).

[0025] The P2 port, P3 port, P4 port, P5 port, and P6 port of the PSE are downlink ports. The P2 port is connected to the network security camera. The P3 port is connected to the network security camera of user A. The P4 port is connected to user B's PC. The P5 port is connected to a PoE switch, and user C uses...

Abstract

The invention discloses a port protection method of power sourcing equipment (PSE) and a PSE. The method comprises: the PSE detects port state information of a port; the PSE uses the port state information to determine a security level of the port; the PSE determines a port protection strategy corresponding to the security level; and the PSE uses the port protection strategy to carry out security protection on the port. According to the embodiment of the invention, the port data can be effectively protected; the port security is enhanced; and a phenomenon that an illegal user obtains legal powered device (PD) data can be prevented.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a PSE port protection method and the PSE. Background technique [0002] Such as figure 1 As shown, a PoE (Power Over Ethernet, active Ethernet) system includes two parts: PSE (Power Sourcing Equipment, power supply device) and PD (Powered Device, power receiving device). Wherein, the PD may be an Ethernet device such as an IP phone, a network security camera, and a wireless AP (Access Point, access point). PoE technology allows power supply through Ethernet cables, and its technical advantages are: improved reliability, centralized power supply, PD does not need an external power supply, only one network cable is required. [0003] In the prior art, since PDs such as IP phones and network security cameras can transmit data in multicast mode, any illegal user can obtain data of other PDs such as IP phones and network security cameras after accessing the PSE, resulting in ...
