•
You must remove the binding of an IRF physical interface to the IRF port before you can
perform any of the following tasks:
Assign the IRF physical interface to the default MDC or a non-default MDC.

Reclaim the IRF physical interface from the default MDC or a non-default MDC.

•
Assigning an IRF physical interface to or reclaiming an IRF physical interface from the default
MDC or a non-default MDC causes the following problems:
The IRF configuration on the interface is lost.

The IRF link is closed.

To avoid IRF fabric split, make sure each member device always has a minimum of one IRF link
in up state.
Restrictions and guidelines for interface configuration
Assigning or reclaiming a physical interface restores the settings of the interface to the defaults.
To configure parameters for a physical interface that has been assigned to an MDC, you must log in
to the MDC.
Configuration considerations
Before assigning physical interfaces and LPUs to MDCs, determine the following items:
•
Number of MDCs.
•
Number of physical interfaces that each MDC needs.
•
Interface numbers of the physical interfaces to be assigned to MDCs.
•
Location of each LPU that holds the physical interfaces to be assigned.
Procedure
1. Determine the MDC requirements, including:
Number of physical interfaces that each MDC needs.

Interface numbers of the physical interfaces to be assigned to MDCs.

Location of each LPU that holds the physical interfaces to be assigned.
