Steps to permanently change an access port to managed from unmanaged

Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:

• Access ports set to Managed are changed to Unmanaged after Smarts IP re-discovery
• Juniper EX4200-48T switch with managed / EXPLICITLY_MANAGED ports are changing to unmanaged on re-discovery.

This article explains for steps using which we could permanently change an access port to managed from unmanaged in Smarts IP?

Environment

Smarts 10.1.X

Cause

By default, access ports in Smarts IP are unmanaged during discovery and re-discovery. If you set access ports to managed using the Smarts IP interface and re-discover the ports, the IsManaged attribute will revert to being false and the ManagedState will change from EXPLICITLY_MANAGED back to UNMANAGED.

Resolution

You can manage the access ports so that the object will be explicitly managed and the Smarts IP post-processing code will not unmanage it again. This is achieved by putting the following code into your custom post processing file, calling the manage() function with over-write parameter set to True:

START {

..eol

} do {
     foreach PortName (getInstances("Port")) {
     PortObj = object(PortName);
     PortObj->manage();
     print("Port state set to Manage ->".PortObj->ManagedState);
     }
}

Additional Information

This workaround would be classified as a customization, and hence please evaluate and test this on UAT/Test environment before introducing this on to the Production environment.
