Adding parameters to running IKE policy will affect associated IPSec

[kay.kang]

Hi,

We're running an IPSec tunnel associated with an IKE policy having following parameters.

Confidentiality algorithm: AES-256

Hash algorithm: SHA-512

DH: 20

And, I am going to add parameters to the IKE policy as below

Confidentiality algorithm: AES-256

Hash algorithm: SHA-512, SHA-256

DH: 20, 14

My question is if this adding parameters will affect any outage of the associated IPSec tunnel.
