"show arp" doesn't seem to list "incomplete" ARP entries - that is, actually saying that it couldn't find the MAC address for a given IP. This is contrary to the normal "arp" command in Linux and other environments.
Is there a different command to list ARP failures?

The underlying OS for Junos is BSD if that helps and you can exist the the shell to see what is visible there.
In Junos your other path for mac information is the ethernet switching commands
show ethernet-switching statistics mac-learning
show ethernet-switching mac-learning-log

Hi NO, going to shell does not help in this case
the CLI "show arp " and the shell command "arp -a" both show exactly the same information in the same format and both are NOT displaying incomplete arp entries.
(I tested and verified it on QFX and MX)
