Hi! Emil is implicitly suggesting you that you should restart from scratch/default (remove interface 1/1/47 from being a LAG member, set "no routing" to involved physical interfaces - you should have more than one on your standalone switch, don't you? - then reapply LAG to involved interfaces).
Are you working on a VSX of two Aruba 8325 or with a Standalone Aruba 8325?
Also, some diagnostic from Aruba 8325 and Cisco Catalyst 3850 side would help too.

I don't think that's work. Once you'd applied the lag to the interface, you cannot apply anything else. But thank you for your response. ^^

Hello
I see a config inconsistency which may cause this.
Lag 98 is configured as Layer 2 lag (no routing) however the physical interface 1/1/47 seems to be still in Layer 3 mode which is the default. I dont see the command no routing in its context. Please go the config context of 1/1/47 and add the command no routing.

I'd tired to connect Aruba 8325 with Cisco 3850. Here is my configure and the error message from Cisco.
