Enabling Enhanced Irf In Irf Mode - HP FlexFabric 12500 Series Configuration Manual

Step
11. Save the running
configuration.
12. Activate the configuration on
the IRF port.

Enabling enhanced IRF in IRF mode

Configuration prerequisites
Before you enable enhanced IRF in IRF mode, complete the following tasks:
Remove MDCs in the IRF fabric. The mdc mdc-name [ id mdc-id ] command is mutually exclusive
•
with the irf mode enhanced command.
If Layer 3 (route mode) Ethernet interfaces exist, you must change the operating mode of these
•
interfaces to Layer 2 (bridge mode). You can enable enhanced IRF only when the device does not
have Layer 3 (route mode) Ethernet interfaces. For more information about the operating modes of
Ethernet interfaces, see Interface Configuration Guide.
Configuration restrictions and guidelines
When you configure enhanced IRF in IRF mode, follow these restrictions and guidelines:
For a successfully IRF merge, make sure enhanced IRF is enabled or disabled on each member
•
device.
To merge IRF fabrics operating in enhanced IRF, you must manually reboot at least the (M- 1 ) member
•
devices to complete the IRF merge. (The letter "M" represents the total number of member devices
in all IRF fabrics.)
To disable enhanced IRF in IRF mode, make sure the following requirements are met:
•
The IRF fabric has no more than two member devices.
Only one IRF port on each member device has physical port bindings.
The system will reboot automatically after you execute the undo irf mode enhanced command. To
•
avoid data loss, follow the system instruction to save the running configuration when you execute the
command.
Configuration procedure
To enable enhanced IRF:
Command
save
irf-port-configuration active
26
Remarks
Activating IRF port
configurations can cause IRF
merge and reboot. To avoid
data loss, save the running
configuration to the startup
configuration file before you
perform the operation.
After this step is performed, the
state of the IRF port changes to
UP, the member devices
automatically elect a master,
and the subordinate device
automatically reboots.
After the IRF fabric is formed,
you can add more physical ports
to an IRF port (in UP state)
without performing this step.
