isr4300-universalk9.16.12.05.SPA.bin really s**t with LACP?

[SystemEngineer32313]

Is this 4331 really start after reload with LACP enabled per-vlan load-balance?

Sorry we are not able to understand the issue here - is the LB is not working, or is the command is the issue ?

port-channel load-balancing vlan-manual

Load Balancing on Port Channels

GEC interfaces can use either dynamic flow-based load balancing or VLAN-manual load balancing. You can configure the load-balancing method globally for all port channels or directly on specific port channels. The global configuration applies only to those port channels for which you have not explicitly configured load balancing. The port-channel configuration overrides the global configuration.

Flow-based load balancing is enabled by default at the global level. You must explicitly configure VLAN load balancing or the load-balancing method is flow-based.

After restart HW (reload) configuration changed from:

interface GigabitEthernet0/0/1
channel-group 1 mode active

to:

interface GigabitEthernet0/0/1
channel-group 1

Can you post show version complete output.

Raise a TAC Case.  
This is a known bug:  CSCvw74609

Also, be aware of CSCvx32090.

Thanks for the idea. I got desperate - not 17.3.2 not 17.2.2 releases did not help. I already thought: "Horrible piece of s**t", back to the bridge IRB. And Torvalds in my head said: take a closer look at this code ... After 15 minutes I wrote an EEM script, it works.
