HPE FlexNetwork 10500 series Command Reference Manual page 48

Parameters
{ interface-type interface-number }&<1-24>: Specifies a space-separated list of up to 24 interfaces.
interface-type interface-number1 to interface-type interface-number2: Specifies a range of
interfaces. The two interface-type arguments must have the same value. All interfaces in the range
must be on the same LPU.
Usage guidelines
You can assign multiple physical interfaces to a non-default MDC. A physical interface must meet the
following requirements to be assigned to a non-default MDC:
•
The interface must belong to the default MDC. To assign a physical interface that belongs to
one non-default MDC to another non-default MDC, you must remove the existing assignment
by using the undo allocate interface command.
•
The interface must not be the console port. The console port of the device belongs to the default
MDC. You cannot assign them to a non-default MDC.
•
The interface must not be the management Ethernet interface. The physical management
Ethernet interface of the device belongs to the default MDC and cannot be assigned to a
non-default MDC. When a non-default MDC is created, the system automatically creates a
virtual management Ethernet interface for the MDC. All the virtual management Ethernet
interfaces use the same interface type and number and the same physical port and link as the
default MDC's physical management Ethernet interface. However, you must assign different IP
addresses to the virtual management Ethernet interfaces so MDC administrators can access
and manage their respective MDCs. The IP addresses for the management Ethernet interfaces
do not need to belong to the same network segment.
When you assign physical interfaces on an IRF member device to MDCs, make sure the default
MDC always has one or more physical IRF ports in up state. Assigning the default MDC's last
physical IRF port in up state to a non-default MDC splits the IRF fabric.
Assigning or reclaiming a physical interface restores the settings of the interface to the defaults. If the
MDC administrator configures the interface during the assigning or reclaiming operation, settings
made before the operation is completed are lost.
To configure a physical interface assigned to an MDC, you must log in to the MDC.
Examples
# Assign interfaces GigabitEthernet 1/0/1 and GigabitEthernet 1/0/3 to MDC sub1.
<Sysname> system-view
[Sysname] mdc sub1
[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/1 gigabitethernet 1/0/3
Configuration of the interfaces will be lost. Continue? [Y/N]:y
# Assign interfaces GigabitEthernet 1/0/1 through GigabitEthernet 1/0/8 to MDC sub1.
<Sysname> system-view
[Sysname] mdc sub1
[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/1 to gigabitethernet 1/0/8
Configuration of the interfaces will be lost. Continue? [Y/N]:y
# Assign interface GigabitEthernet 1/0/4 to MDC sub1.
<Sysname> system-view
[Sysname] mdc sub1
[Sysname-mdc-2-sub1] allocate interface gigabitethernet 1/0/4
Configuration of the interfaces will be lost. Continue? [Y/N]:y
Group error: all interfaces of one group must be allocated to the same mdc.
