Problem with A5120 IRF Stack, after reboot IRF is gone

[MarcoKohler]

Hi

I have a problem with 2 A5120 Switches. The one we have wit one 10GB Module we do not have any Problem, but I have 2 Switches with 2 10GB modules each. If i create a IRF Stack Switch 1 Module1 Port 2 with Switch2 Module1 Port1 it works, till I do a reboot, then the IRF does not work anymore.

I tested following combination:

SwitchA Module 1 Port 2 - SwitchB Module 1 Port 1

SwitchA Module 1 Port 2 - SwitchB Module 2 Port 1

SwitchA Module 1 Port 1 - SwitchB Module 1 Port 1

Alwas the same problem. I also saved the configuration after acctivated the IRF.

Any idea?

If config is needed I can send them tomorrow.

Best,

Marco

Hi,

Yes please send configuration.

It is a out of the box configuration, so I start first to configure the irf:

Switch A:

irf-port 1/2
 port group interface Ten-GigabitEthernet1/1/2 mode normal

Switch B

irf-port 2/1
 port group interface Ten-GigabitEthernet2/2/1 mode normal

After set active, the Switch B reboot and the IRF is established

Everything works well till I reboot the switches. After reboot the IRF, both switch are like standalone

Log from Switch A:

 Ten-GigabitEthernet1/1/2: The transceiver is 10G_BASE_STACK_SFP.

%Apr 26 12:01:23:498 2000 H3C CFM/4/CFM_LOG:
Command port group interface Ten-GigabitEthernet2/2/1 mode normal fails to recover configuration.

Log from Switch B:

 Ten-GigabitEthernet2/2/1: The transceiver is 10G_BASE_STACK_SFP.

%Apr 26 12:21:26:844 2000 H3C IFNET/3/LINK_UPDOWN: Ten-GigabitEthernet2/2/1 link status is UP.
%Apr 26 12:21:32:972 2000 H3C CFM/4/CFM_LOG:
Command port group interface Ten-GigabitEthernet1/1/2 mode normal fails to recover configuration.

Thanks for your help.

Best

Now I did an extended test:

Removed the second 10Gig Module on both switches and configured the IRF like following:

irf-port 1/1
 port group interface Ten-GigabitEthernet1/1/1 mode normal
#
irf-port 2/2
 port group interface Ten-GigabitEthernet2/1/2 mode normal

Everything works well, also after a reboot. Then I powered off both switches reconnected the removed 10G Modules and booted. IRF is not working now. I'm not sure if that should work or not.

I have error and cannot put the command in the second switch for IRF.

 irf member 1 renumber 2

in all the time the log is showing error

any idea ?
