Hi knaik99,

What do you mean? Are you referring to the WAN links' health?

If so, you can go to Menu > Monitor > Network and then you can select and click on a particular device.

Once you're seeing the monitor dashboard for the specific device, then you can locate the WAN section on the left panel and check Loss/Latency/Jitter and some other parameters for TLOCs and Tunnels associated with the device.

You can also check the overall Transport Health in the Main Dashboard (Menu > Dashboard > Main Dashboard and check the Transport Health dashlet).

Please let me know if this helps or if you were looking for something different or more specific.

in Transport health at dashboard,

we are seeing only transport VPN0 health right?

also at network TAB, we are seeing TLOC and tunnel health in WAN section so is it related to DTLS tunnel or IPSEC tunnel

Hello Knaik,

Yes, the transport side is always VPN0nd you are seeing only that in the Transport Health dashlet (loss/latency/jitter).

Regarding Monitor > Network > "Edge Device X" > WAN, the Tunnel view is related to the IPSec tunnels between endpoints (you can see this in the legend of the chart). Remember that you will have these IPSec tunnels (by default) in the Data Plane to establish secure connections between WAN Edge Routers.

If you want to check the control connections (using DTLS by default) then you can check the Control Connections under Security Monitoring. You have these DTLS tunnels between the WAN Edge Routers and the vSmarts and also between vSmarts if we are talking about the control plane.

A good document for you to check these and other SD-WAN concepts in more detail is the following:

I hope this helps.
