keepalive frequency issue

Hi guys,

I have one question, how soon can CSS detect the service status when one service gets down? From cisco.com, I learned that the frequency could be from 2 to 255.

Does that mean 2 seconds to 255 seconds? or check the service 2 times to 255 times in one second?

If check one time every 2 seconds, I think that's too long... may many request will be directed to a down service.

Thank you!

Ed

Ed,

the frequency is measured in seconds.

So 2 seconds is the minimum.

If you had 100 servers and you had to check them 10 times per second, you would need a CPU just for the keepalives.
