Is it possible to Include/Exclude a Cluster and a Host for an SE Group at the same time from the Avi UI?
No, currently, the Avi user interface (UI) does not have the capability of including/excluding a cluster and including/excluding a host for an SE group at the same time.
As of today, the Avi UI supports either including/excluding of a cluster or including/excluding of any host from an SE group. Capability to edit (exclude/include) a cluster and a host at the same time is available from the Avi Vantage command line interface (CLI).
To perform changes for a cluster or a host for an SE group for vCenter cloud, refer the article How to Include/Exclude Cluster and Hosts at the same time for an SE group from the Avi CLI.
