Changing NE IDs and IP addresses

12

ECC protocol identifies NEs by NE ID. The U2000 also identifies NEs by NE ID and uses NE ID as a keyword for search. A unique NE ID must be assigned for each NE during network planning. NE ID conflicts cause ECC route collision, which will result in unreachability of some NEs. In a commissioning or expansion process, you can change NE IDs using the U2000 if required when the original network plan is modified.

Relationship between the IP address and ID of an OTN NE
The ID of an OTN NE is unique in the entire network. When the NE is configured as the gateway NE, the NE uses the IP address for TCP/IP communication with the NMS. For other communications between NEs, the device uses the DCC communication with other devices, and the ID is the only identifier.

Whether the IP address of a WDM NE varies according to the NE ID
If the IP address of an NE is not changed before you change the NE ID, the IP address of the NE varies according to the NE ID. The association between the NE ID and IP address will be automatically released once you manually change the NE IP address. In other words, the NE IP address will not vary according to the NE ID after the NE IP address is manually changed.

Command for changing the IP address of an OSN 1800 NE
To set the IP address of an OSN 1800 NE, run the cm-set-ip command.

Impact of changing the NE ID of OSN 8800
The following functions will be affected if the NE ID is changed for WDM devices: the logical fiber connections (FM), automatic optical power adjustment (OPA), intelligent power adjustment (IPA), automatic level control (ALC), automatic power equilibrium (APE), wavelength locking, optical port protection, OWSP protection, OD, and OD V2.
