you have any issues after you complete these tasks, Troubleshoot the Silver
Peak Remote Network.
Supported Software Versions and Requirements
The Silver Peak-Prisma Access solution is
qualified with the following Silver Peak software versions:
- 8.1.9.0
Supported IKE and IPSec Cryptographic Profiles
You onboard your SD-WAN edge devices using
a remote network connection between the edge device at the branch
site, HQ, or hub to Prisma Access. Use Panorama to create a remote
network connection and create IKE and IPSec crypto profiles; then,
set up an IPSec tunnel between the SD-WAN edge device and Prisma
Access, using the same crypto profiles you used in Panorama.
The
following table documents the IKE/IPSec crypto settings that are
supported with Prisma Access and Silver Peak SD-WAN. 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.
