x440 stack enable sharing issue

[Chingis_Taltae1]

I have an issue with LAG across stack (4x Summit x440-24t-10G stacked via SummitStack-V):

Slot-3 Stack.18 # sh slot

Slot-1 X440-24t-10G X440-24t-10G Operational 26

Slot-3 X440-24t-10G X440-24t-10G Operational 26

The stack seems to be OK, all nodes are online and operational, XOS version 15.5.4.2 on all nodes.

I need to create 8 ports LAG (LACP enabled) across stack (SFP ports 23-24 on each stack node), but something goes wrong:

Slot-3 Stack.21 # enable sharing 1:23 grouping 1:23-24,2:23-24,3:23-24,4:23-24 lacp
Error: No valid port(s) in the specified "portList" value "1:23-24,2:23-24,3:23-24,4:23-24".
Configuration failed on backup Node, command execution aborted!

I tried to create 2 ports static LAG across stack (for example copper Ethernet 1:1,2:1 with 1:1 as master port), but got similar issue:

Slot-3 Stack.22 # enable sharing 1:1 grouping 1:1,2:1
Error: No valid port(s) in the specified "portList" value "1:1,2:1".
Configuration failed on backup Node, command execution aborted!

Hi Chingis,

Just to narrow down, can you try to add a port from the master switch to the sharing.

configure sharing 1:1 add ports 3:1

Check if this works! This would help us to narrow down the issue to only adding ports from the standby node.
Looking forward to your response.

Everything looks good based on the outputs. Can you do a "reboot stack-topology" and then attempt to create the lag? I only ask this because based on the "show ports" output it looks like this is a newly built stack and you are preparing it for production (Based on no active ports).

Not a known issue that we are already aware of. It could be a synchronization issue between the master and slot 2. I would not even generalize the sync issue for all the standby nodes as slot 4 worked fine. An upgrade could help! If the issue happens again in recommended version, I would suggest contacting GTAC.
