A network administrator is configuring several HP Comware switches as an HP Intelligent Resilient Framework
(IRF) virtual device. According to best practices at, which point during the IRF configuration process should theadministrator activate the IRF ports?
A.
After enabling the physical interfaces that are assigned to IRF ports and saving the settings
B.
After configuring IRF ports but before assigning physical interfaces to them
C.
After enabling the physical interfaces that are assigned to IRF ports but before saving the settings
D.
Before configuring IRF ports or assigning physical interfaces to them
Explanation:
(see steps 5 and 6 below)
Use the irf-port-configuration active command to activate configurations on all IRF ports on the device.
When you physically connect members of an IRF virtual device and bind physical IRF port(s) to an IRF port
whose link state is DIS or DOWN, which you can display with the display irf topology command, execution of
this command is required to establish the IRF virtual device.
Note that activating IRF port configurations may cause merge of IRF virtual devices and automatic device
reboot. Therefore, to avoid configuration loss you are recommended to set the member ID for the device in the
following way:
1) Plan the network and member IDs in advance. Determine the number of IRF ports to be created, and
which physical IRF ports is used for IRF virtual device establishment.
2) Change member IDs. (Member ID change takes effective after device reboot, so change member IDs
before executing the irf-port-configuration active command.)
3) Connect SFP+ cables or fibers and make sure that the physical IRF ports are well connected.
4) Create IRF ports.
5) Bind physical IRF ports to IRF ports.
6) Save the current configurations to the configuration file to be used at the next startup.
7) Activate configurations on all IRF ports.
When the system starts up, if you bind a physical IRF port to an IRF port through the configuration file, or add a
new physical port, configurations on IRF ports are automatically activated without the need to execute this
command again.
