How to Execute the API commands in vCSA 6.0 Shell?

The API commands in the vCenter Server Appliance let you perform various administrative tasks in the vCenter Server Appliance. The API commands are provided by appliance management service in the vCenter Server Appliance. You can edit time synchronization settings, monitor processes and services, set up the SNMP settings, firewall and so on. Here is step by step of how to execute API Commands:-
1. Access vCSA Shell Locally (Alt+F1) or through SSH

2. Enable the vCSA Shell by using this command or through vCSA DCUI:-

shell.set --enabled true

3. Run this command to list all API commands:-

help api list 

4. Let's assume you want to check firewall rule those are created on vCenter Run this API command:-

com.vmware.appliance.version1.networking.firewall.addr.inbound.list

5. I have one rule in vCenter. Now if you want to delete these rules you can execute this API Command:-
com.vmware.appliance.version1.networking.firewall.addr.inbound.delete --position INT  

Replace INT with Rule Integer Value

Example:-

com.vmware.appliance.version1.networking.firewall.addr.inbound.delete --position 0
