How long a kernel’s table entry can be inactive? The OVS kernel’s table can inactive, by default, during a time interval less than 5 seconds. After 5 seconds being inactive, the flow entry is removed from the table. This time is dictated by ovs-vswitchd.
From the original post:
”ovs-vswitchd determines how long the flow should stay in the kernel flow table. By default, it expires a flow after five seconds of inactivity. It can be more aggressive if the flow table becomes large.”
