SG350X ARP Table Overflow Issues

[cleight]

Hello community,

Hoping someone can assist with my issues. I keep getting ARP Table Overflow messages and devices on the network dropping off. I am currently running (2) Cisco SG350X-24P switches in a stack in Layer 3 mode. I have approximately 1600 devices connected behind this stack of switches, the IP Address Table keeps hitting a max of 896 IP's. I cannot seem to figure out how to increase this value, all online resources show the ARP table should handle at least 4k addresses.

Active Firmware on switches is 2.4.5.71

The attached picture is 5 minutes after clearing the ARP table.

Hi,

We are also getting ARP table overflow errors. We have about 200 devices. I've tried adjusting the ARP settings to alleviate the issues to no avail. Our device is also an SG350X-24P. This has brought us down several times before. When I look at the table, only about 83 entries are listed.
