Customer reported they are observing child interface xe-3/0/8 under lacp output for ae28 in detached state even after removing the lacp related configurations under child interface

We could observe from the below logs xe-3/0/8 is still showing under LACP output for ae28

Informed the customer to perform the below workaround and check the LACP status

• Please make the port xe-3/0/8 administratively down and check the status of lacp & "show interface terse" output for xe-3/0/8
• Please remove the LACP configuration on the remote end which is connected to xe-3/0/8 and remove the peer end port configured under lag.
•  Please check the port key configuration in both current and peer device. If exists, make sure to remove those configurations 
• Please make sure xe-3/0/8 is not configured under any other LAG
• Reconfigure ae28 in MW and check the status
• If issue still persists restart respective FPC in MW
