In Huawei's optical network products, the Optix 155/622H ( Metro1000 ) ,OSN1500B, and Optix 2500+ (Metro3000 ) are three devices that are relatively common. Among them, Optix 155/522H (commonly known as the small box), Huawei OSN1500B (B-type subrack) These two devices appear more in the access layer, while Optix 2500+ is generally found in structures like the aggregation layer. I'll describe the settings for these three device ID numbers here.

There are two types of Huawei Metro1000, V2 and V3:

1, V2 version of the small box is using hardware dialing code, there are 16 white dialing switches on the SCB main control board, left and right every 8 sets. The group on the left, the first four bits from left to right are the high four bits, we usually do not move it, according to the default down to put there. We dial a total of 12 bits, the left four bits and the right eight bits, from right to left to start dialing, 1 for up, 0 for down. For example, there is a network element ID of 66. First call up the computer to start ----- program ----- attachment ----- calculator. 设为科学型，在十进制里输入66，点二进制便能得到了，为1000010。所以对应的我们应从右向左拨：下上下下下下上下下下下下下下下（后四位不要动）。 After dialing a good in the main control board to find: RST key, with a pointed thing to press, at the same time look at the main control board that indicator, after a while at the same time, indicating that the main control board is being reset, after a while can be.

2, V3 version of the small box is the use of software dialing code:

You can use Navigator to search, find the connection, password: nesoft, and check the forced login. When you are logged in, type :cm-set-neid:0x0009(hexadecimal number);

Such commands start with :start; end. Note the format. Let's also take 66 as an example, the decimal number of 66 is 42. so we enter the command :cm-set-neid:0x000942 When the setup is successful, the master board is automatically reset.

You can use the network management to set the ID, select file-device search, search for this device and right click to create the neid, wait until it is created successfully and then right click to modify the ID - delete and rebuild the neid after successful setup.

Note: When I do the experiment, because the device and the network management is through TCP/IP communication, my network management IP to be set to the same network segment with the device, that is, 129.9.*. *. Subnet mask: 255.255.0.0. The gateway does not have to be set. And because these devices may have been artificially modified by others when doing experiments in the past, when we modify the ID again, the IP is not changed automatically. The network administrator cannot find the IP, and the network element is grayed out, making it impossible to log in. At this time, use Navigator to log in, enter the command :cm-set-ip:129.9.*. *; here 129.9.*. Here 129.9.*. is the corresponding IP after you change the ID, then the network element becomes green, we can start the business configuration.

3, Huawei Optix 2500 + (Metro3000 ) using hardware dialing, pull out the SCC main control board, there are two sets of upper and lower 8-digit dialing switches, the upper group for the high 8-digit, the lower for the low 8-digit, how to dial refer to the V2 of the small box.

Here is some more ID knowledge:

Each device in a network corresponds to a unique identifier, i.e., the network element ID. the ECC communication between the network element devices is carried out through the network element ID identification. The network manager uses the network element ID in the interface or database to identify the different network element devices in the network. It is specified in the Optix transport device that the network element ID is a 24-bit binary number, or three bytes. The dip switches on the main control board of the network element make up the lower 16 bits of the element ID, and the upper 8 bits of the ID are the extended ID (default is 9), also known as the "subnet number", which is often used to identify different subnets.

IP=129.9.A.B, and ID=A*256+B. So when ID is 66, A is 0 and B is 66. IP is 129.9.0.66.
