Set an integer to correspond to the stack ID of a stack member. For devices that are not capable of being stacked, set with the value 1. For a chassis switch, it corresponds to the card ID. For VCStack Plus, 1-12 refers to the cards on VCS stack member 1 and 13-24 refers to the cards on VCS stack member 2. Refer to chassisMappingTable for more details. Subsequent SNMP queries to the atFilev2Table will use this as the stack member to generate a file listing from. NOTE: atFilev2Table and associated objects have been replaced by atFilev2FileViewer.
