This read-only SnmpAdminString value holds the internal numeric identifier UCS Manager assigned to this Default vNIC/vHBA Behavior policy instance when it was created. This ID is for UCS Manager's own internal bookkeeping and object correlation across its database rather than something an admin chooses, so it stays fixed for the life of that Default vNIC/vHBA Behavior policy instance even if its name or DN changes. When correlating a Default vNIC Behavior policy set to auto-create vNICs from network template 'vNIC-Templ-A' for every profile in an organization that omits explicit vNICs against UCS Manager's own logs or fault records, this internal ID is the stable key that ties the SNMP row back to the same underlying managed object over time.
