NOTE:
•
To realize IRF link redundancy and load sharing and increase the bandwidth and reliability of IRF links,
bind one IRF port to multiple physical IRF ports by repeatedly executing the port group interface
command. You can bind up to two physical IRF ports to an IRF port. The physical ports of an IRF port
must be located on the same interface card.
•
Before binding a physical IRF port to an IRF port or canceling such a binding, you must manually disable
the physical IRF port (that is, execute the shutdown command on the port). After finishing your
operation, you should manually bring up the physical IRF port (that is, execute the undo shutdown
command on the port). The system may prevent you to shut down a port to avoid anomalies. Then, follow
the system instructions to disable its peer port.
•
If you need to shut down two physical IRF ports of an IRF link, execute the shutdown command first on
the port that is on the master switch or close to the master switch, and then on the other port that is
comparatively far from the master switch.
•
If you set the IRF operating mode of the physical IRF port by providing the mode keyword when you bind
the physical port to the IRF port, you must configure its directly connected physical IRF port to work in the
same mode.
•
If you need to unplug the interface card on which an physical IRF port reside after an IRF fabric is
established, unplug cables for IRF connection, or execute the shutdown command on the physical IRF
port to disable the port, and then unplug the interface card.
•
If a common Ethernet interface functions as a physical IRF port and is bound to an IRF port, you can
execute only the cfd, default, shutdown, description, and flow-interval commands on the physical IRF
port. For more information about these commands, see
Layer 2 - LAN Switching Command Reference

Specifying a priority for a member switch
The greater the priority value, the higher the priority. A member with a higher priority is more likely to be
a master.
Follow these steps to specify a priority for a member switch:
To do…
Use the command…

Specify a priority for a member of
an IRF fabric
irf member member-id priority priority
Optional
The priority of a member defaults
to 1
NOTE:
The setting of priority takes effect right after your configuration without the need of rebooting the switch.
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:
To do…
Use the command…
