Intracluster Port dna check failed

[haroungh]

Hi Dears, 

I have only one dnac server and am  trying to re image it  

I have used the entreprise interface as cluster interface, the  dnac install process stucked when trying to validate the cluster interface (screenshoot : failed to validate cluster interface)   .

is it mandatory to use the dedicated cluster interface, or how to pass this error ?

One interface must be configured as the cluster link interface. You can mark your enterprise interface as the cluster-link interface, but best practice is to just configure your dedicated cluster interface even if you won't be configuring a cluster for the time being.
