Problem with Cisco Firepower 2100 reimaged ASA

[fbarducci]

Hello,
I actually reimed a cisco firepower 2100 in asa.
The problem is that when I go to create the port channels I can do it without problems but I can't associate the ethernet with the channel-group x mode active command because it answers me that the command does not exist. Is there any feature to be enabled to do this?
thank you so much
regards

You can only see the port-channel config on the ASA running on the 2100.l Any changes to membership have to be done on the FXOS:

EtherChannel member ports are visible on the ASA, but you can only configure EtherChannels and port membership in FXOS.

If you change the EtherChannel configuration after you enable failover, make the interface changes in FXOS on the standby unit, and then make the same changes on the active unit.
