Supported IKE and IPSec Cryptographic Profiles
The following table documents the IKE/IPSec crypto settings that are supported with
Prisma Access and Cisco Catalyst SD-WAN, formerly known as Viptela SD-WAN, devices.
Use the recommended settings when you onboard a remote network and define IKE and
IPSec cryptographic settings when connecting the Prisma Access and Cisco Catalyst
SD-WAN device.
A check mark indicates that the profile or architecture type is supported; a dash (—)
indicates that it is not supported. Default and Recommended settings are noted in
the table.
