All commands indicated to be in "MDC view" are only available in the view for a non-default MDC. You can use the mdc command to enter the view of the default MDC, but in this view you can only display the relevant settings.

Unless otherwise stated, the term "MDC" in this section refers to a non-default MDC.

allocate interface

Use allocate interface to assign a physical interface to an MDC.

Use undo allocate interface to reclaim a physical interface assigned to an MDC.

Syntax

allocate interface { interface-type interface-number }&<1-24>

undo allocate interface { interface-type interface-number }&<1-24>

allocate interface interface-type interface-number1 to interface-type interface-number2

undo allocate interface interface-type interface-number1 to interface-type interface-number2

Default

All physical interfaces on the device belong to the default MDC, and a non-default MDC has no physical interfaces to use.

Views

Predefined user roles

network-admin

mdc-admin

Parameters

{ interface-type interface-number }&<1-24>: Specifies individual interfaces by their types and numbers. &<1-24> indicates that you can specify up to 24 interfaces.

interface-type interface-number1 to interface-type interface-number2: Specifies a range of interfaces. The interface-number1 argument indicates the number of the first interface for the range, and the interface-number2 argument indicates the number of the last interface for the range. All interfaces in the range must be of the same type and on the same interface card.

Usage guidelines

The console port and AUX port of the device always belong to the default MDC. They cannot be assigned to a non-default MDC.

The management Ethernet interface of the device always belongs to the default MDC. When a non-default MDC is created, the system automatically creates a management Ethernet interface for the MDC. The management Ethernet interfaces of all non-default MDCs use the same type and number and the same physical port and link as that of the default MDC. However, you must assign them different IP addresses so administrators of different MDCs access and manage their respective MDCs. The IP addresses for the MDCs' management Ethernet interfaces might belong to the same network segment or different segments.

Only a physical interface that belongs to the default MDC can be assigned to a non-default MDC.

You can assign multiple physical interfaces to an MDC.

One physical interface can belong to only one MDC. To assign a physical interface that belongs to one non-default MDC to another non-default MDC, you must first remove the existing assignment by using the undo allocate interface command.

Because of hardware restrictions, the interfaces on some interface cards are grouped. The interfaces in a group must be assigned to the same MDC at the same time.

Assigning a physical interface to or reclaiming a physical interface from an MDC restores the settings of the interface to the defaults.

To configure parameters for a physical interface assigned to an MDC, you must log in to the MDC.

After you change the configuration of a physical IRF port, you must use the save command to save the running configuration. Otherwise, after a reboot, the master and subordinate devices in the IRF fabric will have different physical IRF port configurations and you must use the undo allocate interface command and the undo port group interface command to restore the default and reconfigure the physical IRF port. For more information about the undo port group interface command, see IRF Command Reference.

Parameters

name mdc-name: Specifies an MDC by its name, a case-insensitive string of 1 to 15 characters. If you do not specify this option, the command displays the interfaces of all MDCs.

Usage guidelines

The default MDC can use only the physical interfaces that are not assigned to a non-default MDC. When you assign physical interfaces to MDCs on an IRF member device, make sure the default MDC always has at least one physical IRF port in up state. Assigning the default MDC's last physical IRF port in up state to a non-default MDC splits the IRF fabric.

limit-resource cpu

Use limit-resource cpu to specify a CPU weight for an MDC.

Use undo limit-resource cpu to restore the default.

Syntax

limit-resource cpu weight weight-value

undo limit-resource cpu

Default

The default MDC has a CPU weight of 10 (unchangeable) on each MPU and each interface card, and each non-default MDC has a CPU weight of 10 on each MPU and each interface card that it is authorized to use.

Views

MDC view

Predefined user roles

network-admin

mdc-admin

Parameters

weight weight-value: Specifies a CPU weight value in the range of 1 to 10.

Usage guidelines

The amount of CPU resources an MDC can use depends on the CPU weight settings for all MDCs that share the same CPU. For example, if three MDCs share the same CPU and their weights are 10, 10, and 5, the two MDCs with the same weight can use the CPU for approximately the same period of time, and the MDC with a weight of 5 can use the CPU for about half of the time for each of the other two MDCs. Specifying the following weights for the MDCs has the same effect: 2, 2, and 1.

After you specify a CPU weight for an MDC, the MDC can use the same percentage of CPU resources on the MPUs and the interface cards assigned to it. To enable an MDC to use the CPU on an interface card, use the location command to authorize the MDC to use the interface card first.

Examples

# Set the CPU weight of MDC sub1 to 2.

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource cpu weight 2

limit-resource disk

Use limit-resource disk to specify a disk space percentage for an MDC.

Use undo limit-resource disk to restore the default.

Syntax

In standalone mode:

limit-resource disk slot slot-number ratio limit-ratio

undo limit-resource disk slot slot-number

In IRF mode:

limit-resource disk chassis chassis-number slot slot-number ratio limit-ratio

undo limit-resource disk chassis chassis-number slot slot-number

Default

All MDCs share the disk space in the system, and an MDC can use all free disk space in the system.

Views

MDC view

Predefined user roles

network-admin

mdc-admin

Parameters

slot slot-number: Specifies an MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies an MPU on an IRF member device. (In IRF mode.)

ratio limit-ratio: Specifies the ratio of the disk space an MDC can use on the specified card to the total disk space of the card, in the range of 1 to 100.

Usage guidelines

An MDC can apply for and use more space only when the space it is using is less than the space indicated by its disk space percentage.

The amount of space indicated by the percentage for an MDC must be greater than the least space the MDC requires for operation. If the amount of space indicated by the percentage for an MDC is less than the least space required, the MDC does not release the extra part it has occupied, but no more folders or files can be created or saved for the MDC.

Different MDCs might have different basic space requirements. Before you specify a disk space percentage for an MDC, use the display mdc resource command to view how much space the MDC is using. If the MDC administrators have not accessed the MDC, you can assume that the amount of space used by the MDC is the basic space requirement of the MDC.

Examples

# Allow MDC sub1 to use up to 30 percent of the disk space on the MPU in slot 1. (In standalone mode.)

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource disk slot 1 ratio 30

# Allow MDC sub1 to use up to 30 percent of the disk space on the MPU in slot 1 on IRF member device 2. (In IRF mode.)

<Sysname> system-view

[Sysname] mdc sub1

[Sysname-mdc-2-sub1] limit-resource disk chassis 2 slot 1 ratio 30

limit-resource memory

Use limit-resource memory to specify a memory space percentage for an MDC.

Use undo limit-resource memory to restore the default.

Syntax

In standalone mode:

limit-resource memory slot slot-number ratio limit-ratio

undo limit-resource memory slot slot-number

In IRF mode:

limit-resource memory chassis chassis-number slot slot-number ratio limit-ratio

undo limit-resource memory chassis chassis-number slot slot-number

Default

All MDCs share the memory space in the system, and an MDC can use all free memory space in the system.

ratio limit-ratio: Specifies the ratio of the memory space that an MDC can use on the specified card to the total memory space of the card, in the range of 1 to 100.

Usage guidelines

This command sets the maximum amount of memory space that an MDC can use. Make sure this amount is greater than the minimum amount of memory space that an MDC needs to start.

Examples

# Allow MDC sub1 to use up to 30 percent of the memory space on the card in slot 1. (In standalone mode.)

<Sysname> system-view

[Sysname] mdc sub1

Parameters

mdc-name: Specifies the MDC name, a case-sensitive string of 1 to 15 characters.

id mdc-id: Specifies an MDC ID in the range of 1 to 4. If you do not specify this option, the system assigns the lowest ID number among the available ones to the MDC.

Usage guidelines

· The default MDC is system predefined. You do not need to create it, nor can you delete it.

· The device supports creating up to three MDCs.

· Only an MPU with 4G memory space supports creating MDCs.

· To enter the view of an existing MDC, you can specify the MDC name, or specify both the MDC name and the MDC ID. If you specify both the MDC name and the MDC ID, make sure the two arguments identify the same MDC.

· Delete an MDC with caution. Deleting an MDC removes all configurations and harddisk files of the MDC, and the configurations and files cannot be restored.

· This command is mutually exclusive with the irf mode enhanced command. For more information about IRF, see IRF Configuration Guide.

Examples

# Create an MDC named sub1.

<Sysname> system-view

Usage guidelines

After an MDC is started, administrators of the MDC can log in to the MDC for MDC configuration and maintenance.

Stop an MDC with caution. Stopping an MDC interrupts all services on the MDC and logs out all users of the MDC.

To avoid configuration loss, save the running configuration of an MDC before stopping the MDC.

Examples

# Start MDC sub1.
