MDC probe commands -- display system internal mdc block-information

Use display system internal mdc block-information to display MDC block information.

Syntax

Centralized devices:

display system internal mdc id mdc-id block-information

Distributed devices in standalone mode:Centralized IRF devices:

display system internal mdc id mdc-id block-information [ slot slot-number cpu cpu-number ]

Distributed devices in IRF mode:

display system internal mdc id mdc-id block-information [ chassis chassis-number slot slot-number cpu cpu-number ]

Parameters

id mdc-id: Specifies an MDC by its ID. The value range varies by device model.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays MDC block information for all cards. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command displays MDC block information for all IRF member devices. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. On an IRF fabric, this command displays MDC block information for all member devices if you do not specify a member device. On an IRF 3 system, this command displays MDC block information for all IRF member devices and PEXs if you do not specify an IRF member device or PEX. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays MDC block information for all cards. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. The slot number is fixed at 0 for the PEX. On an IRF fabric, this command displays MDC block information for all cards if you do not specify a card. On an IRF 3 system, this command displays MDC block information for all cards and PEXs if you do not specify a card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

Use this command to identify the MDC block reason and locate the problem.

MDC probe commands -- display system internal mdc configuration-status

Use display system internal mdc configuration-status to display the execution status of MDC-related configuration commands on cards.

Syntax

display system internal mdc configuration-status

Usage guidelines

When the device reboots or a card is installed, the device or card starts the MDC process and executes the MDC-related configuration commands. You can use this command to examine the configuration command execution status and locate any cards that have problems.

MDC probe commands -- display system internal mdc running-status

Use display system internal mdc running-status to display MDC operating status on cards.

Syntax

display system internal mdc id mdc-id running-status

Parameters

id mdc-id: Specifies an MDC by its ID. The value range varies by device model.

Usage guidelines

Use this command to identify the following items:

· Cards that have MDC problems.

· Phases in which the problems occur.
