Parameters
mdc mdc-id: Specifies the ID for an MDC, in the range of 1 to 4. If an MDC is specified, this
command binds physical ports on the MDC to an IRF port. If no MDC is specified, this command
binds physical ports on the default MDC to an IRF port.
interface-type interface-number: Specifies a physical port by its type and number.
interface-name: Specifies a physical port in the interface-typeinterface-number format. No space is
allowed between the interface-type and interface-number arguments.
Usage guidelines
The MDC settings may lose effect after the device reboots to join an IRF fabric. HP recommends
creating an MDC and binding its physical ports to an IRF port after the IRF fabric is formed. For
more information about MDC, see Fundamentals Configuration Guide.
In IRF mode, use the shutdown command to shut down the physical port before binding it to the
IRF port or removing it from the IRF port. After the binding operation is complete, use the undo
shutdown command to bring up the physical port, and execute the irf-port-configuration active
command to active the IRF port configuration. After the binding removal operation is complete, use
the undo shutdown command to bring up the physical port.
In standalone mode, the shutdown and undo shutdown operations are not required.
Repeat the port group interface command to bind up to 12 physical ports to an IRF port for link
redundancy.
The system does not dynamically remove the binding between a physical port and an IRF port,
even if the IRF link has been lost, for example, because the interface card holding the physical port
is removed. To remove the binding, first shut down the physical port and then use the undo port
group interface command. If the interface card holding the physical port is removed, you do not
need to execute the shutdown command before removing the binding.
Examples
# In standalone mode, bind port Ten-GigabitEthernet 2/0/1 to IRF-port 1.
<Sysname> system-view
[Sysname] irf-port 1
[Sysname-irf-port1] port group interface ten-gigabitethernet 2/0/1
# In IRF mode, bind port Ten-GigabitEthernet 1/2/0/1 to IRF-port 1 of member 1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/2/0/1
[Sysname-Ten-GigabitEthernet1/2/0/1] shutdown
[Sysname-Ten-GigabitEthernet1/2/0/1] quit
[Sysname] irf-port 1/1
