port group interface
Use port group interface to bind a physical interface to an IRF port.
Use
undo port group interface to remove the binding of a physical interface to an IRF port.
Syntax
port group interface interface-type interface-number
undo port group interface interface-name
Default
No physical interfaces are bound to an IRF port.

Parameters
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.
Usage guidelines
Execute this command multiple times to bind multiple physical interfaces to an IRF port. You can
bind a maximum of two physical interfaces to an IRF port.
Make sure the IRF physical interfaces of an IRF port use the same binding mode. In IRF mode, you
cannot configure IRF physical interfaces of an IRF port to use different binding modes. In standalone
mode, you can configure the IRF physical interfaces of an IRF port to use different binding modes.
However, only one binding mode takes effect after the operating mode changes from standalone to
IRF. The binding mode of the first IRF physical interface in the configuration file has the highest
priority.
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.
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.
If you use physical interfaces that are grouped in hardware for IRF connection, follow these
restrictions and guidelines:
If you use one physical interface in a group as an IRF physical interface, the remaining physical
interfaces in the group can only act as IRF physical interfaces. You cannot use them for any
other purposes. To use a physical interface in a group for any purpose other than IRF physical
interfaces, do not bind any of the interfaces in the group to an IRF port.
The physical interfaces in a group can be bound to different IRF ports.
You must shut down all physical interfaces in a group before you can assign or remove any of
the interfaces to or from an IRF port. To bring up the interfaces after the assignment or removal
is complete, execute the
undo shutdown command.
