What is Dangling mode and continuos Channel mode in VPN?

Can you please tell me where the question is coming from? Typically this is very in depth IKE knowledge not very useful for anyone outside of vendor support and developers.

At a simplified level.

Continuous channel - we will keep IKE SA up as long as there is an IPsec SA up.

Dangling mode - we will let the IPsec SAs "dangle" without support of IKE SA.

There is not much in config to do in config that can change this behavior.

As far as I remember :

- ASA - all CCM

- IOS - all dangling except ezvpn.

But as I said, this sort off detail is rarely needed by anyone but vendor.
