How to fix IPv4 neighbor Table Overflow

i havd same message in logo list. Can any one help me to end this problem
ipv4 neighbor table overflow, please consider increasing max-neighbor-entries
And i dont connect any thing as dvr.

Hi,
V7.16.1

IP Settings.
There are 2 items, the max neighbor entries and Arp Timeout
You could increase the max neighbor entries value or possibly decrease the Arp Timeout value.
(The current default Arp Timeout value appears to be 30S, I would not go below that)

Thanks i do show that 2 items and setting it. As you tell me after that i send you the result.
