The syntax for adding a new attribute to an existing ICIM class is:

refine interface <ICIM_class_name>
{
<attribute declarations>
}

The following example adds the stored attribute SM_SerialNumber to the existing Router class.

refine interface Router
{
 stored attribute string SM_SerialNumber
 “Custom serial number stored in the Cisco”
 “chassis-id MIB (.1.3.6.1.4.1.9.3.6.3)”
 = “NotAvailable”;
}

For more information about attribute declarations and valid data types, see the VMware Smart Assurance MODEL Reference Guide.
