Hi George,

>From the man page for ovf-ofctl:

idle_timeout=seconds       Causes the flow to expire after the given
number of seconds of inactivity.
                                       A value of 0 prevents a flow
from expiring due to inactivity. The default is 60 seconds.

Hope that helps.

Todd
