Method used to check the total number of ARP entries on USG firewalls

Method used to check the total number of ARP entries on the USG2000, USG5000, and USG6000:
The USG firewalls do not provide a special command used to view the ARP entry statistics. You can run the display arp command and view the total number of ARP entries in the last line. For example:
display arp
IP ADDRESS MAC ADDRESS EXPIRE(M) TYPE INTERFACE VPN-INSTANCE
------------------------------------------------------------------------------
2.2.2.3 00e0-fcd6-6f66 I GE0/0/0
------------------------------------------------------------------------------
Total:1 Dynamic:0 Static:0 Interface:1
When a large number of ARP entries exist on the firewall, you can run the following command to view the total number of ARP entries:
display arp | in Total
Total:1 Dynamic:0 Static:0 Interface:1
