This field appears only when the Inband-Health Check is set to Remove.
Enter the number of seconds after a server has been marked as failed to reconsider it for sending live
connections. Valid entries are integers from 30 to 3600. The default setting is 0. The setting of this option
affects the behavior of the real server in the inband failed state, as follows:
• When this field is not configured and has the default setting of 0, the real server remains in the failed
state until you manually suspend and then reactivate it.
• When this field is not configured and has the default setting of 0 and then you configure this option
with an integer between 30 and 3,600, the failed real server immediately transitions to the Operational
state.
• When you configure this field and then increase the value, the real server remains in the failed state for
the duration of the previously-configured value. The new value takes effect the next time the real server
transitions to the failed state.
• When you configure this field and then decrease the value, the failed real server immediately transitions
to the Operational state.
• When you configure this field with an integer between 30 and 3,600 and then reset it to the default of
0, the real server remains in the failed state for the duration of the previously-configured value. The
default setting takes effect the next time the real server transitions to the failed state. Then the real
server remains in the failed state until you manually suspend and then reactivate it.
• When you change this field within the reset-time interval and the real server is in the OPERATIONAL
state with several connection failures, the new threshold interval takes effect the next time that a
connection error occurs, even if it occurs within the current reset-time interval.
Predictor Specify the method for selecting the next server in the server farm to respond to client requests. Round
Robin is the default predictor method for a server farm.
See Table 5-12 for the supported predictor methods and configurable attributes for each predictor method.
