This object carries a text identifier for a Resource Manager client on the mobile gateway, formatted as either 'ms-a/b/c' or 'pfe-a/b/c' where a, b, and c denote the FPC slot, PIC slot, and port of the hardware module involved. It's only meant to be seen as part of an SNMP trap/notification, letting an administrator immediately pinpoint which physical line card and port a Resource Manager event pertains to. For example, a notification carrying the value 'ms-2/1/0' tells the admin the event involves the services module in FPC slot 2, PIC slot 1, port 0.
