Environment : This article applies to all the controllers running a minimum OS version 6.x.x.x and VIA client 2.0
Separate VIA connection profiles are not required for IKEv1 and IKEv2. A single VIA connection profile can be configured with both IKEv1 and IKEv2 settings. Depending on the capabilities of the VIA client, either an IKEv1 or an IKEv2 connection is established. By default, the VIA 2.x clients first attempt IKEv2 if the “Enable IKEv2” option is set in the VIA connection profile. If the VIA client is not able to establish an IKEv2 connection, it falls back to using IKEv1. All VIA 1.x clients directly establish an IKEv1 connection.
