( severity neq informational ) and ( eventid eq nego-fail ) and ( description contains 'LACP interface ethernet1/21 moved out of AE-group ae1. Selection state Selected' ) and ( receive_time leq '2019/03/01 11:50:57' )

I check the switch logs all is good.

Have you verified Layer 1?  I would check your cabling first.  That's a pretty fast flicker if I'm reading your logs correctly.  Also, are you using "lacp fast" or "lacp slow" timers?  You could be mismatched.

Layer 1 is good.

My side is slow.

I would match those then.  Fast/Fast or Slow/Slow.  Those decide the timers on each side of the LACP aggregate and they really should match.

can anyone please confirm this?

 

Fast/Fast or Slow/Slow.  LACP timers should match?
