In VELOS platform, the ideal timeout for HW entries is 5 mins(Hw eviction timeout). However, when you delete the VS/Zone configuration it will initiate the eviction immediately(Software eviction). In this case, the eviction does not happen as expected and causes the entry to continue to stay at sPVA for some time.
This issue causes the sPVA entries to stay for 5 minutes(Ideal eviction timeout) even after the Corresponding Zone configuration is deleted.
This issue happens when we configure Zone based DDOS with Aggregation or BD in VELOS platform.
The issue is with handling software eviction cases in the Zone scenario. The code is updated to handle the software eviction in a similar way as the virtual server scenario.
