Description
Holorouter Version
9.1
VCF Version
VCF 9.1
Target Type
vCenter Cluster
Describe the bug
When trying to deploy v9.1 using a vDS, the documentation screenshot states the Promiscuous mode as Reject and MAC learning enabled.
This is the correct setup. However the Precheck checks the Promiscuous mode instead of the maclearning status.
Reproduction steps
- Do a new deployment towards a vCenter server with vDS
Expected behavior
To install correctly.
Relevant logs
Additional context
Workaround:
Set-vdSecurityPolicy -AllowPromiscuous:$false before starting deployment.
change to Set-vdSecurityPolicy -AllowPromiscuous:$true after check is complete
