DHCP Static Mappings hostnames won't show up at the arp table?

[badogski29]

Hi, I have a few static mappings and gave those mappings hostnames. Now when I go to my arp table, hostnames won't show up. I'm not sure what am I doing here wrong?

They will only show up in the ARP table if the firewall has had a need to exchange traffic with them.

did you ping the devices from the firewall?  Did the devices talk to the firewall?  As Derelict mentions only when the device and the firewall have actually talked will they show in the table.
