I was wondering what will happen, if the dedicated DUAL ACTIVE link in a SVL setup fails? Would there be any disruption, in terms of traffic? Or in terms of SSO states? I see documentation about SVL links failure. However, I can't seem to find an answer the questions above. Any help would be appreciated.
Best practice for the Stack Wise Virtual :
Stackwise Control Plane Recommendations
StackwiseVirtual Link & Dual Active Detection
For the SVL Link, it is good to use two 10/40 GbE ports on separate ASIC’s for resilientconnectivity.
SVL links should be point-to-point connection.
•It is recommended that you use a dedicated link for Dual Active Detection.
If all Fails same like Split Brain - Need to manually shutdown 1 Device to make network working.
If the DAD link fails, there should not be any traffic disruption or changes to the SSO state. But you will lose the capability the detect a split-brain scenario if all the Stackwise Virtual Links were to go down.
