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 virtual private LAN service (VPLS) function in an IRF fabric, configure the 10
GE optical ports on the SE, EA 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, default,
description, and flow-interval commands. For more information about these commands, see
Layer 2

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:
To do… Use the command… Remarks
Enter system view system-view —
Enable auto reboot for IRF fabric
merge
irf auto-merge enable
Optional
Disabled by default.
NOTE:
The auto reboot function does not take effect on the IRF fabric merge caused by binding an IRF port with
a physical IRF port in IRF mode. You must manually reboot the switches that have been defeated in the
master selection to complete the merge.
Configuring a description for a member switch
You can configure a description for a member switch to identify its physical location, or for any other
management purpose.
Follow these steps to configure a description for a member switch:
