Gateway ID

A gateway ID refers to the ID of an NE serving as a gateway.

Gateway IP

IP address is used for TCP/IP communication between an NE and the NM, which is effective only when it is used for TCP/IP communication. That is, only the gateway NE needs the IP address. IP address cannot be used to identify an NE uniquely. NEs in different TCP/IP networks may have the same IP address. And one NE may have several IP addresses (for example: IP of the dial-up network, IP of the Ethernet port and so on). In essence, the NE ID has nothing to do with the NE IP. Either the NE ID or the IP can be separately set. But IP address is set to be consistent with the ID by default, that is, IP = 0x81000000+NE ID. In other words, if ID is 0x090001, IP is set to "129. 9.0.1" by default. After the IP address is set manually, the change of ID will no longer affect the IP address. When the IP address manually set is canceled, the IP will be changed accordingly.

Gateway NE

Gateway NE refers to the NE that communicates with the NMS via Ethernet or serial port line. The non-gateway NE communicates with the gateway NE via ECC and communicates with the NMS via the gateway NE. The gateway NE is a communication route that the must pass through when managing the entire network. The communication status between the gateway NE and the can be:(1) Normal: The current communication is efficient; (2) Connecting: The destination gateway responds, and the communication is interrupted but is being connected; (3) Disconnected: The destination gateway does not respond (Maybe the network cable is disconnected or not within the same network segment), and the communication is unreachable or the gateway is disabled manually.
