Usage Guidelines

Usage Scenario

When you need to query the neid value written in the flash of the main control board, run this command.

In VS mode, this command is supported only by the admin VS.

Example

The actual command output varies according to the device. The command output here is only an example.

# Query the neid value written in the flash.

Table 2-1190 Description of the display mpu neid command output
Item Description
mpu

MPU.

set mainboard neid

Function

The set mpu neid command sets a 24-bit NE ID that is written into an MPU in a specific slot of a device. After the device is powered on, the VRP reads the NE ID and generates an NE IP address.

Format

set mpu slot slot-id neid id-number

Parameters

Parameter Description Value
neid id-number

Specifies the network element ID.

The value ranges is 10001 to fefffe , in hexadecimal notation.
slot slot-id

Specifies a slot ID.

The value is a string of 1 to 31 case-sensitive characters without spaces.

Usage Guidelines

Usage Scenario

Before shipment, an NE ID is written into an MPU. To set the NE ID run the set mpu neid command. After the device is powered on, the VRP reads the NE ID and generates an NE IP address used to negotiate with the DCN protocol. Implementation Before shipment, the NE ID of each device is written into flash memory.

Implementation Procedure

Before factory, the production equipment executes the command line to write the Flash Neid process.

Configuration Impact

If the NE ID in flash memory conflicts with that of another device, the VRP reads the NE ID and generates an NE ID conflict alarm.

Precautions

In VS mode, this command is supported only by the admin VS.

As a unique identifier of a DCN network element, the NEID must ensure the unique NEID of all the device nodes in the network. NEIDs of all NEs in the same DCN network can not collide with each other. Otherwise, the DCN network can not communicate.

Example

# Write the NEID to the MPU in slot 1.
<HUAWEI> system-view
[~HUAWEI] diagnose
[~HUAWEI-diagnose] set mpu slot 1 neid 10001
