Use display device to display device information.

Syntax

In standalone mode:

display device [ flash ] [ slot slot-number [ subslot subslot-number ] | verbose ]

In IRF mode:

display device [ flash ] [ chassis chassis-number [ slot slot-number [ subslot subslot-number ] ] | verbose ]

Parameters

flash: Specifies a Flash. If you do not specify this keyword, the command displays information about all cards on the device.

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number: Specifies an IRF member device by its member ID. If you do not specify this option, the command displays hardware information about all IRF member devices in the IRF fabric. (In IRF mode.)

subslot subslot-number: Specifies a subcard by its subslot number. The switch does not support subcards.

verbose: Displays detailed hardware information. If you do not specify this keyword, the command displays brief information.

The output shows that the device has one MPU (in slot 10), one interface card (in slot 1).

Table 30: Command output

Field	Description
Slot No.	Slot number of the card.
Brd Type	Hardware type of the card.
Brd State	Card status: Standby—The card is the standby MPU or a switching fabric module. Master—The card is the active MPU or a switching fabric module. Absent—The slot is not installed with a card. Fault—The card is faulty and cannot start up. Normal—The card is an interface card and is operating correctly. Offline—The card is a switching fabric module and its forwarding plane is in isolated state.
Subslot	Maximum number of subcards that the card supports. The switch does not support subcards.
Sft Ver	Software version of the card.
Patch Ver	Patch version of the card.

# In IRF mode, display device information about all IRF member devices.

The output shows that the IRF fabric has two member devices. The card in slot 10 on member device 1 is the global active MPU. The card in slot 10 on member device 2 is the global standby MPU.
