On the EX platform, this command will show you all the tail drops the switch knows about.  One thing to note here:  If a switch is showing you it is dropping packets, chances are, it is dropping a lot more than this.  You may need to fan out your connectivity more.  I’ll go into more detail on the EX4500 and EX4200 concerns in another post.
