Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] see figure 1 As shown, the method for maintaining an optical transmission network based on the remote login protocol provided by the embodiment of the present invention includes the following steps:
[0023] S1. Establish the Ethernet channel between the network element management unit and the single disk, obtain the single disk ID (IDentity, identity identification number) number and generate the single disk MAC (Medium / MediaAccessControl, media access control) address and IP (Internet Protocol, network access control) The mapping table corresponding to the address of the interconnection protocol).
[0024] S2. Send a command on the network element management system to enable the port monitoring and forwarding service of the network element management unit. The network element management unit includes a packet listener, a pac...

The invention discloses a method for maintaining an optical transmission network based on a telnet protocol and relates to the field of communication. The method comprises the following steps: Ethernet channels between an element management unit and single disks are established, and ID (Identity) numbers of the single disks are acquired and a corresponding mapping table between MAC (Medium Access Control) addresses and IP (Internet Protocol) addresses of the single disks is generated; a command is issued on an element management system so as to enable a port monitoring and forwarding service of the element management unit; after the command is received by the element management unit, the element management unit turns on a packet monitor and a packet forwarder, starts up the telnet server side, and responds successful command to the element management system; the element management system starts up the telnet client and is connected with the telnet server side of the element management unit; and a user establishes connection with a specified address and a specified port through the telnet client of the element management system, logs onto a management system of the single disks, and carries out command line debugging. According to the method for maintaining the optical transmission network based on the telnet protocol, a random single disk of a network element can be remotely logged on without on-site debugging, so that the maintenance cost is saved, and the maintenance efficiency is increased.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for maintaining an optical transmission network based on a remote login protocol. Background technique [0002] The optical transmission network is composed of EMS (Element Management System, network element management system) and multiple network elements. Each network element is composed of multiple single disks with different functions and network element management units. The network element management unit is EMS Managed NE objects. Each single disk and the network element management unit run an independent embedded management system, and use the Ethernet interface (Ethernet) in the network element to communicate. The optical transmission channel ECC (Embedded Control Channel, embedded control channel, that is, the embedded control channel for transmitting information of the network element management system) is used for communication between different network elements an...
