Parameters
mdc mdc-id: Specifies an MDC by its ID. The MDC must already exist on the device. If the
candidate IRF physical interface is on a non-default MDC, you must specify the MDC. If the
candidate IRF physical interface is on the default MDC, you do not need to specify the MDC.
interface-type interface-number: Specifies a physical interface by its type and number.
interface-name: Specifies a physical interface in the interface-typeinterface-number format. No
space is allowed between the interface-type and interface-number arguments.
mode enhanced: Specifies the enhanced binding mode for the physical interface. An IRF physical
interface operates in enhanced mode regardless of whether you have specified these keywords.
Usage guidelines
The MDC settings might lose effect after the device reboots to join an IRF fabric. As a best practice,
create an MDC and bind its physical interfaces to an IRF port after the IRF fabric is formed. For
more information about MDCs, see Fundamentals Configuration Guide.
In IRF mode, use the shutdown command to shut down a physical interface before you bind it to or
remove it from an IRF port. To bring up the physical interface after a binding or binding removal
operation, use the undo shutdown command.
In standalone mode, the shutdown and undo shutdown operations are not required.
Repeat the port group interface command to bind a maximum of eight physical interfaces to an
IRF port for link redundancy.
The binding mode takes effect only after the IRF binding takes effect.
The system does not dynamically remove IRF port bindings when IRF links are lost, for example,
because an interface card is removed. To remove IRF port bindings, you must use the undo port
group interface command.
For more information about IRF port binding requirements, see IRF Configuration Guide.
