This option is useful when troubleshooting an NSX Advanced Load Balancer integration with VMware cloud.

Instructions

Log into the NSX Advanced Load Balancer Controller shell prompt and enter the verifylogin command. The NSX Advanced Load Balancer will return the following output based on the verification status:

[admin:Controller-16-3-6]: > verifylogin vcenter vcenter_url 10.10.2.10 username root password vmware
+-------------------------+------+-------------------+
| Uuid                    | Name | Managed Object Id |
