Usage Guidelines

Usage Scenario

When a board is faulty or in device routine maintenance, the display device command can be used to display information about the board or module. For example, you can view the running status of the board, power module, or fan module. The information helps you check whether the device is running properly.

Precautions

After the fault is rectified, run the display device command to view the hardware status and the registration status. The information helps you check whether the faulty component is recovered and running properly.

Example

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

**Table 1** Description of the **display device** command output
Item	Description
Status	Status of a component.
Type	Type of an installed device, which varies according to the device type and hardware.
Port_count	Number of interfaces on a PIC.
Init_result	Initialization result.
Logic_down	Logic down status, also known as protocol down.
Slot	Slot ID of an installed device.
Online	Whether a device is installed: Present: A device is installed. Offline: No device is installed. Offline is displayed after a device is removed, but the configuration on this slot is not deleted. You do not need to configure repeatedly when the same type device is inserted.
Register	Whether a device is successfully registered.
Role	Role of a component: MMB: Master and slave control board. LC: Line card. OTHERs: Other board types.
LsId	Logical router ID of the logical Router which a device belongs to.
Primary	Whether the component has a backup. NA indicates that the component does not have a backup.
Pic	Number of a PIC.
