Creating An Mdc; Assigning Hardware Resources To An Mdc; Authorizing An Mdc To Use An Lpu - HP FlexFabric 12500 Series Configuration Manual

Tasks at a glance
(Required.)
Although you can assign hardware resources to MDCs before or after you start the MDCs, HP
recommends that you assign resources to MDCs before starting the MDCs.

Creating an MDC

You can create MDCs only on MPUs with a memory space that is equal to or greater than 4 GB.
The maximum number of non-default MDCs depends on the MPU model:
A standalone device or an IRF fabric that uses LST1MRPNE1 MPUs supports up to eight non-default
•
MDCs.
A standalone device or an IRF fabric that uses LST2MRPNC1 MPUs supports up to three non-default
•
MDCs.
The enhanced IRF mode and the MDC feature are mutually exclusive. For more information about IRF, see
Virtual Technologies Configuration Guide.
To create an MDC:
Step
1. Enter system view.
2. Create an MDC.

Assigning hardware resources to an MDC

When you create an MDC, the system automatically assigns CPU, storage space, and memory space
resources to the MDC. You can adjust the resource allocations as required.
An MDC needs interfaces to forward packets. However, the system does not automatically assign
interfaces to non-default MDCs. You must assign interfaces to non-default MDCs. Resources that are not
assigned to non-default MDCs belong to the default MDC.

Authorizing an MDC to use an LPU

By default, all LPUs of the device belong to the default MDC, and a non-default MDC cannot access any
LPUs or resources on the LPUs. To assign physical interfaces to an MDC, you must authorize the MDC to
use the LPUs to which the physical interfaces belong.
Some LPUs can be shared by multiple MDCs. See
Accessing an MDC
Command
system-view
mdc mdc-name [ id mdc-id ]
Remarks
N/A
By default, there is a default MDC with the name
Admin and the ID 1.
The default MDC is system predefined. You cannot
delete it.
The MDC starts to operate after you execute the
mdc start command.
