Related Configuration Options
The following configuration options enable or disable the Keep-Alive feature:
kpl-interval
Default Value: 10
Valid Value: Any integer from 0-600
Changes Take Effect: Immediately
Related Feature: Keep-Alive Feature Handling
Specifies a keep-alive interval (in seconds). To check network connectivity, T-Server issues a dummy CTI request at the interval specified when there is no other activity on the link. A value of 0 (zero) disables this feature. See, the kpl-tolerance option.
The value of this option may need to be increased to avoid false restarts, if the switch is slow to respond—for example, during busy periods.
kpl-loss-rate
Default Value: 10, 100
Valid Value: Any single integer or comma-separated pair of integers
Changes Take Effect: Immediately
Related Feature: Keep-Alive Feature Handling
Specifies how many KPL positive responses are needed to decrement either the failure or warning tolerance counter. A value of 0 (zero) disables this option. Two comma-separated values signifies that T-Server calculates both the failure counter and the warning counter (the failure rate is always the lower value).
A single value signifies that T-Server calculates only the failure counter.
Note: This option has no effect if the value of the kpl-tolerance option is set to 0 (zero). In this case, a single KPL failure triggers a link restart.
kpl-tolerance
Default Value: 3
Valid Value: Any integer from 0-10
Changes Take Effect: Immediately
Related Feature: Keep-Alive Feature Handling
Specifies the threshold number of accumulated failed keep-alive requests that T-Server permits before considering the CTI link to be interrupted. When this threshold is reached, T-Server treats the CTI link as either:
- Lost—T-Server tries to reconnect to the CTI link.
- Unstable—T-Server issues a warning message.
See, the kpl-interval option.
