Scenario :

Users utilize the ARP table to monitor MAC and IP corresponding information. IP addresses may change or be released from time to time in users' network environment, and users may want to know the ARP table refresh time in USG Flex / ATP models.

Answer :

Users can use the CLI command "show arp-table" to monitor the ARP table, and its refresh time is 1 minute. For example, if the IP 192.168.33 with a MAC address e8:d8:d1:XX:XX:XX is disconnected from the LAN1 port, after 1 minute, the MAC address information will be removed from the ARP table.
