<p>The present application discloses a network element access method, a system, and a device. The method includes the following steps: sending, by a network element attempting to access a network, an access data request to a network element that has accessed the network, so that the network element that has accessed the network forwards the access data request to a network management element; receiving, by the network element attempting to access the network, an access data response sent by the network element that has accessed the network, where the access data response is generated by the network management element by performing authentication after the network management element receives the access data request forwarded by the network element that has accessed the network, and the access data response is sent, to the network element attempting to access the network, by the network management element via the network element that has accessed the network; and if the access data response indicates that the network element attempting to access the network is allowed to access the network, accessing the network. Because a secure link has established between the network element that has accessed the network and the network management element, the network element that has accessed the network and that has relatively high security performance can be used, so as to prevent an attack and improve security performance.</p> |
