Hello, 2 computers on same subnet can see each each other or can ping but after 10 to 15 minutes they lose the ping and no connectivity is seen between them.. there is no configuration on switch all ports are in default vlan. it is happening with 4 switches right now.

Please check the "show configuration vlan" after the issue occurs and see if flooding is disabled.

Then you are hitting the issue mentioned in the below article, this issue is fixed fromĀ 21.1.1.4 patch 1-5

I do not think 16.x is an option for X440-G2's the minimum required software version isĀ 21.1.1
