Hello,
Today, I would like to share with you this topic which Introduce the relationship between network element ID and IP for the OSN equipment.
ECC communication between network elements is carried out through ID address identification, so each network element must have an independent identifier ID. In addition, the network management also uses the network element ID when identifying different network elements in the interface / database as the searched keyword to mark each network element in the network. ID consists of two parts: basic ID and extended ID. If the extension IDs of two network elements with the same basic ID are different, the IDs of the two network elements are also different.
In the OptiX device, we stipulate that the network element ID is a 24-bit binary number, that is, three bytes. The lower 16 bits of the ID are the base ID, and the upper 8 bits of the ID are the extended ID (default is 9), also known as a subnet number (subnet), which can be used to identify different subnets. The complete ID is composed as follows:
0x xx xx xx
Hexadecimal 09 A B
Extended ID Base ID
When extended ID = 9, we often say ID = base ID (decimal) = A × 256 + B;
When the extended ID ≠ 9, if the extended ID = 8, the corresponding ID = 8 × 256 × 256 + A × 256 + B;
Essentially, ID has nothing to do with IP, and ID and IP can be set independently. However, the IP address is set to be consistent with the ID by default, that is, IP = 0x81000000 + ID, that is, if the ID is 0x090001, the IP is 129.9.0.1 by default. If the IP address is manually set, the ID change will no longer affect the IP address. If you cancel the manually set IP address, the IP will change with the ID.
