Are permanent connections wholly removed on CSS ?

[snakayama]

Hi,

On the CSS, I understand if I do not want to change connection state to idle/inactive, I can configure either command to keep the connection state "active" as permanent connections.

flow permanent

flow-timeout-multiplier

My question is the permanent connections created by above command are wholly removed from connection table and internal cache (inside the list) when client or server send FIN or ACK that is CSS receives FIN or RST from client or server for the permanent connections ?

Or CSS keeps permanent connection on its connection table even if CSS receives FIN or RST from client or server for the permanent connections ?

Best regards,

flow permanent port command tells CSS to Not

remove any flow "that has not seen a TCP RST or a FIN Ack".

Answer to your question is

Yes "Flow permanent" takes down the flow if the connection is gracefully terminated other wise the FCB's would go really fast :)
