default TCP profile - idle timeout vs keepalive
Nice short one... the default TCP idle timeout is 300 seconds, yet the default keepalive interval is 1800. What's going on here? Is there some subtlety I'm missing here? How does it wait 6 times longer that than maximum idle timeout to send a keepalive packet??
- HamishCirrocumulusShort answer, it doesnt. But if you set the keepalive less than the idle timeout it would be able to.
- Chris_PhillipsNimbostratusRight, so why the bizarre defaults?? if that's the intended behavior, then the keepalive should be set to zero surely? It's pretty misleading I think, as I would think users are given to believe they must be *good* defaults...
- hooleylistCirrostratusThe only thing I can think of is maybe the default is set so that keepalives will only be used if the idle timeout is increased past 1800 seconds.
- Samir_Jha_52506NoctilucentCan we configure TCP profile timeout 14400sec. user said to configure it. i am not sure whther LB will support or not.
- nitassEmployeeCan we configure TCP profile timeout 14400sec. user said to configure it. i am not sure whther LB will support or not.do you mean tcp idle timeout?
[root@ve10:Active] config b profile tcp test idle timeout 14400 [root@ve10:Active] config b profile test list profile tcp test { idle timeout 14400 }
- Samir_Jha_52506NoctilucentI have configured like this. but it is not working. can any one please suggest me on this.

It is logging us out prematurely instead of keeping the session open. - Samir_Jha_52506NoctilucentIt is logging us out prematurely instead of keeping the session open.
- nitassEmployeeIt is logging us out prematurely instead of keeping the session open.you do see tcp reset being sent from bigip to both client and server, don't you?
