purposes. To use a port in a group for any purpose other than IRF physical interfaces, do 
not bind any of the ports in the group to an IRF port.  

−

  The ports in a group can be bound to different IRF ports. 

−

  You must shut down all ports in a group before you can assign or remove any of the 

ports to or from an IRF port. To bring up the ports after the assignment or removal is 
complete, execute the 

undo shutdown

 command. 

To identify ports in a port group, use the 

debug port mapping

 command in probe view. 

Ports that have the same unit value belong to the same group. 

IMPORTANT: 

The following information varies by device model: 

•

Candidate IRF physical interfaces. 

•

Port binding restrictions. 

•

Applicable transceiver modules or cables.  

For more information, see configuration and installation guides for the device. 

6. 

Verify that all IRF links are up: 

a. 

Execute the 

display irf topology

 command, and then check the 

Link

 field. 

−

 If 

the 

Link

 field for each IRF port does not display 

DOWN

, go to step 

7

. 

−

 If 

the 

Link

 field for an IRF port in use displays 

DOWN

, go to step 

b

. 

b. 

Execute the 

display irf link 

command, and then check the 

Status

 field of the physical 

interfaces bound to the IRF port. 

−

  If the field displays 

DOWN

 or 

ADM

 (administratively down) for all the physical interfaces, 

remove the link failures or use the 

undo shutdown

 command to bring up the 

administratively down interfaces. 

−

  If the field displays 

UP

 for a minimum of one of the physical interfaces, go to step 

c

. 

c. 

Save the configuration, and then execute the 

irf-port-configuration active

 command in 

system view to activate the IRF port configuration. 

IMPORTANT: 

Activating IRF port configuration requires a reboot. To prevent configuration loss, you must 
save the configuration before you execute the 

irf-port-configuration active

 command.  

7. 

Verify that all member devices use the same software version: 

a. 

Execute the 

display version 

command to identify the software version of each member 

device. 

b. 

Upgrade the software of all member devices to the same version. As a best practice, 
upgrade the earlier versions to the most recent version. 

NOTE: 

Typically, the 

irf auto-update enable

 command can automatically synchronize a member 

device with the software version of the master device. However, the synchronization might fail 
when the gap between the software versions is too large. For more information, see the release
notes. 

8. 

If the issue persists, contact H3C Support.
