# NEVPNIKEv2DeadPeerDetectionRate

An enumeration of values for the frequency at which the IKEv2 client runs the dead peer detection algorithm.

```
enum NEVPNIKEv2DeadPeerDetectionRate
```

## Topics

### Detection rates

[`NEVPNIKEv2DeadPeerDetectionRateNone`](/documentation/NetworkExtension/NEVPNIKEv2DeadPeerDetectionRate/none)

Do not perform dead peer detection.

[`NEVPNIKEv2DeadPeerDetectionRateLow`](/documentation/NetworkExtension/NEVPNIKEv2DeadPeerDetectionRate/low)

Run dead peer detection once every 30 minutes. If the peer does not respond, retry 5 times at 1 second intervals before declaring the peer dead and terminating the session.

[`NEVPNIKEv2DeadPeerDetectionRateMedium`](/documentation/NetworkExtension/NEVPNIKEv2DeadPeerDetectionRate/medium)

Run dead peer detection once every 10 minutes. If the peer does not respond, retry 5 times at 1 second intervals before declaring the peer dead and terminating the session.

[`NEVPNIKEv2DeadPeerDetectionRateHigh`](/documentation/NetworkExtension/NEVPNIKEv2DeadPeerDetectionRate/high)

Run dead peer detection once every 1 minute. If the peer does not respond, retry 5 times at 1 second intervals before declaring the peer dead and terminating the session.
