Hello,
What could be possible tests for a test plan in SD-WAN?
Thanks.

Hi @Uhmazing I think I do not understand your question, what do you want to test?

Hi @osdesent, when I create a POC on my SD-WAN Topology, I also have to test if things work correctly. So I have to set up a test plan.
My question is, what kind of tests scenario's could I use to test in my POC?

Are you going to use virtual or physical enviroment for your POC?

Virtual (POC tool in Cisco dCloud)

The dCloud SD-WAN POC tool is a very powerful enviroment that allows you to create any custom topology(virtually) deploying a single or multiple sets of controllers, vedges, cedges with differnt versions and IOS-XE (CSR1kv) and VyOS.
With all of this you can create any topology and configurations you want, like central and local policies, devices & feeature teamplates leveraging several tools to create data payload, transports, sites and their respective underlay and more.
Here you have quick guide for the SD-WAN POC Tool

Hi Uhmazing,
Here are a few tests I generally think about when I design an SD-WAN environment:
1) Are control connections up over all expected transports? ("Show control connections / Show sdwan control connections")
2) Are BFD (SD-WAN data plane) tunnels up to all expected remote SD-WAN routers? ("show bfd sessions / show sdwan bfd sessions")
3) Are all expected LAN routing protocol relationships formed at the site with the SD-WAN router(s)?
4) If above 3 conditions are met, perform critical application testing by using an end-user PC and navigating to the business critical applications.
5) Some customers choose to run iPerf or other speed capture / traffic generation tests before and after implementing SD-WAN at a site to compare results
6) Failover tests (if there is redundancy). Some examples include:
There are of course other failover tests, but these are obviously critical ones.
7) Ensure no traffic asymmetry is present if possible. The application inspection engine of the SD-WAN routers don't like asymmetry. Traffic should generally enter and leave the site via the same vEdge or cEdge router and use an active / standby setup, with the exception that the standby may be serving TLOC-extension to the primary.
Apart from this I can't think of anything major. The point is to make sure the box forms all expected connections, that the end user experience and critical applications work, and that failover works (if available).
Hope it helps!
