Assigning Physical Interfaces To An Mdc - HP 12500 Configuration Manual

To authorize an MDC to use an interface card:
Step
1. Enter system view.
2. Enter MDC view.
3. Authorize the MDC
to use an interface
card.

Assigning physical interfaces to an MDC

By default, all physical interfaces belong to the default MDC, and a non-default MDC has no physical
interfaces to use for packet forwarding. To enable a non-default MDC to forward packets, you must
assign it interfaces.
The console port and AUX port of the device always belong to the default MDC and cannot be assigned
to a non-default MDC.
Configuration guidelines
IMPORTANT:
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.
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 interface 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 can 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. The
default MDC can use only the physical interfaces that are not assigned to a non-default 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.
Assigning a physical interface to or reclaiming a physical interface from an MDC restores the settings of
the interface to the defaults.
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. For information about interface group, see
device prompt. On an interface card with memory of 512 MB, all the interfaces belong to the same group,
and they must be assigned to the same MDC.
To configure parameters for a physical interface assigned to an MDC, you must log in to the MDC.

N/A
By default, all interface cards of
the device belong to the default
MDC, and a non-default MDC
cannot use any interface card.
You can authorize multiple MDCs
to use the same interface card.
