By default, no physical ports are
bound to any IRF port.
Repeat this step to assign
multiple physical ports to the IRF
port for link redundancy.

The system will prompts you that
an IRF fabric merge will happen.
You need to reboot one of switch
that has failed in the election, and
it will join the IRF fabric as a slave
switch.

NOTE:
•
The maximum number of physical IRF ports that can be bound to an IRF port is eight. When the upper
limit is reached, the execution of this command fails.
•
The switch allows you to bind multiple physical IRF ports on different LPUs to one IRF port.
•
The
mode
keyword in the
port group
command specifies the working mode of a physical IRF port. By
default, the working mode of a physical IRF port is
normal
. An SC card does not support configuration
of the working mode of physical IRF ports as
enhanced
.
•
Physical IRF ports that connect two member switches of an IRF fabric must be configured to work in the
same mode.
•
To use the MPLS L2VPN or VPLS function in an IRF fabric, configure the 10 GE optical ports on the SD
or EB card as the physical IRF port, and configure the working mode of physical IRF ports as
enhanced
.
•
Before you create or remove an IRF port binding, always shut down the physical IRF port. After you are
finished, perform the
undo
shutdown
command to bring up the port. If the system prevents you from
shutting down a port for avoiding anomalies, follow the system instructions to disable its peer port.
•
On an Ethernet port functioning as a physical IRF port, you can execute only the
shutdown
,

,

, and
flow-interval
commands. For more information about these commands, see

Enabling auto reboot for IRF fabric merge
When merging two IRF fabrics, you must reboot the member switches in the IRF fabric that has been
defeated in the master election. The auto reboot function enables the IRF fabric to automatically reboot
all its member switches to complete the merge.
This function can work only when it is enabled on both IRF fabrics that are merging.
Follow these steps to enable auto reboot for IRF fabric merge:
