administrators can access and manage their respective MDCs. The IP addresses for virtual
management Ethernet interfaces do not need to belong to the same network segment.
•
The interface belongs 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 LPU where the interface resides is not assigned to any MDC.
When you assign physical interfaces and LPUs to MDCs, follow these guidelines:
•
For an MDC to use a physical interface, you must perform the following tasks:
a. Assign the physical interface to the MDC.
b. Authorize the MDC to use the LPU where the physical interface resides.
•
Interfaces on LPUs are grouped. The interfaces in a group must be assigned to or removed
from the same MDC at the same time. Different groups of interfaces on an LPU can be
assigned to different MDCs. For interface grouping information, see
Table 43 Interface grouping on LPUs
LPU type
LSV1QGS12SA1(JG683A)
LSVM1QGS12FX1(JG683B/JH127A)
LSVM1TGS24FX1(JG845A/JH126A)
LSVM1QGS6C2FX1(JH002A/JH128A)
•
A physical interface can be assigned to only one MDC.
•
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 parameters for a physical interface that has been assigned to an MDC, you must
log in to the MDC.
•
To use the shutdown command to shut down the management Ethernet interface, you must be
on the default MDC.
When you assign physical interfaces and LPUs to MDCs on an IRF fabric, also follow these
guidelines:
•
To remove an LPU that holds the IRF physical interface of a non-default MDC, first complete the
following tasks:
a. Remove the IRF physical interface configuration for the LPU.
b. Use the save command to save the running configuration.
•
IRF links can belong to the default MDC or non-default MDCs. As a best practice for link
availability, establish a minimum of two IRF links by using different LPUs. An IRF link can
belong to one or more MDCs. The two IRF physical interfaces of an IRF link can belong to the
same MDC or different MDCs.
•
To assign an IRF physical interface to an MDC or reclaim an IRF physical interface from an
MDC, complete the following tasks:
c. Use the shutdown command to shut down the interface.
d. Use the undo port group interface command to remove the binding of the physical
interface to the IRF port. For more information about the undo port group interface
command, see Virtual Technologies Command Reference.
e. Assign or reclaim the IRF physical interface.
f. Use the save command to save the running configuration.
Interface grouping
Each LPU has two groups. The first six interfaces belong to one
group, and the remaining interfaces belong to the other group.
Each LPU has one group. All interfaces on the LPU belong to the
group.
Each LPU has two groups. The first four interfaces belong to one
group, and the remaining interfaces belong to the other group.
