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 [ cpu cpu-number ] ratio limit-ratio

undo limit-resource memory slot slot-number [ cpu cpu-number ]

In IRF mode:

limit-resource memory chassis chassis-number slot slot-number [ cpu cpu-number ] ratio limit-ratio

undo limit-resource memory chassis chassis-number slot slot-number [ cpu cpu-number ]

Default

All MDCs share the memory space of the MPUs in the system. An MDC can use all the free memory space.

Parameters

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

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

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. The value range is 1 to 100.

cpu cpu-number: Specifies a CPU by its number. If you do not specify this option, the command specifies a memory space percentage for CPU 0.

Usage guidelines

The memory space percentage setting for an MDC applies to all MPUs.

This command sets the maximum amount of memory space that an MDC can use. Make sure this amount is sufficient for the MDC to operate correctly.

Examples

# In standalone mode, allow MDC sub1 to use up to 30 percent of the memory space on the switching fabric module in slot 10.

<Sysname> system-view
[Sysname] mdc sub1
[Sysname-mdc-2-sub1] limit-resource memory slot 10 ratio 30

# In IRF mode, allow MDC sub1 to use up to 30 percent of the memory space on the switching fabric module in slot 10 on IRF member device 2.

<Sysname> system-view
[Sysname] mdc sub1
[Sysname-mdc-2-sub1] limit-resource memory chassis 2 slot 10 ratio 30
