I am having the same problem or almost.
I figured out how to create a new VLAN in UCS Central and to set org permissions. But I cannot figure out how to publish a UCS Central VLAN to several UCS Domains that are registered with the UCS Central.
Is this somehow possible with the current UCS PowerTool kit?
Unfortunately, the "publish VLAN" command is only available via SSH CLI on UCS Central and not via GUI. Therefore I cannot convert the GUI actions into some PowerShell code.
Or if somebody knows if it is possible to convert SSH CLI commands into PowerShell commands, then that would help as well.
SSH CLI commands for pushing/publishing a VLAN to a UCS domain:
connect resource-mgr
scope domain-mgmt
scope ucs-domain <DOMAIN-ID>
publish vlan <VLAN-NAME>
Any help or advice is appreciated :-)
