PAN-OS 6.1 introduced the following command to increase the capacity of the Address Resolution Protocol (ARP) table and the MAC address table on PA-3020 and PA-3050 devices:
PA> debug system arp-mac-capacity increased
On the PA-3020 the ARP table capacity can be increased from 1500 to 3000.
On the PA-3050 the number of table entries can be increased from 2500 to 5000.
Note: This change requires a reboot. Once the command is run, the system will ask for confirmation and if there is HA, it must be run on both peers.
