Re: How to troubleshoop flapping ports?

You can create a group that applies the no-trap to every interface.

set groups MYGROUP interfaces <*-*> no-traps

set apply-groups MYGROUP

Then override this with traps on the desired interfaces only

set interfaces ge-0/0/0 apply-groups-except MYGROUP

set interfaces ge-0/0/0 traps
