Binding physical ports to IRF ports
NOTE:
The A7500 switch uses 10 GE optical ports, which are on the main processing unit (MPU), or on SC, SD,
or EB card, as physical IRF ports to perform IRF connection. For more information about LPUs providing 10
GE optical ports, see
HP A7500 Switch Series Installation Guide.
To establish IRF connection, you must assign the physical ports that connect IRF member switches to IRF
ports. An IRF port can be bound to either one or multiple physical IRF ports.
Follow these steps to bind physical ports to IRF ports:
To do…
Use the command…

By default, no IRF port is created
on the switch.
If the IRF port has been created,
this command enters IRF port

Required
By default, no physical ports are
bound to any IRF port.
CAUTION:
•
A physical IRF port can be bound to an IRF port only when it operates in Layer 2 (bridge) mode. For
more information about port link mode, see
Layer 2 — LAN Switching Configuration Guide.
•
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. 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 SD or EB card as the physical IRF port, and configure the working mode of
physical IRF ports as
enhanced
.
•
In standalone mode, binding a physical port to an IRF port does not affect the current configuration of
the port. However, when the operating mode changes to IRF mode, the default configuration of the
physical IRF port restores, and you can only execute the
shutdown
,

, and
flow-interval
commands on the physical port. For more information about these commands, see
