Configure VPN Keep-Alives for Circuit Categories
Let us learn to configure VPN Keep-Alives for circuit
categories.
For metered links, where there is a cost for
usage (such as LTE interfaces), VPN keep-alives can be adjusted to
minimize the usage of the link and any costs associated with using
the link. VPN keep-alives can also be modified for unreliable circuits that
experience high latency and loss such as satellites.
- Navigate toPolicies (Original), orStacked Policies, orSecurity Policies (Original), selectCircuit Categories.
- Edit a circuit category and enter values forKeep-Alive Failure CountandKeep-Alive Interval.
- ForKeep-Alive Failure Count, enter a value between 3 and 30.TheKeep-Alive Failure Countindicates the number of consecutive missed keep-alive packets before a link is declared as down. The default value is 3.
- ForKeep-Alive Interval, enter a value between 100 ms and 600000 ms.TheKeep-Alive Intervalindicates the time interval in milliseconds between two VPN keep-alive packets. The default value is1000 ms.
- SelectUse for Controller ConnectionsandUse for Application Reachability Probes, as required for this selected circuit category.
- ClickUpdate.
