This value is the administrator-configured enabled/disabled state for this internal link, as tracked on the Fabric Interconnect side. It matters on the same internal chassis backplane link, but the record kept on the Fabric Interconnect (switch) side rather than the IOM/server side because the switch-side adminState should match its ServerIntFIo counterpart on the IOM side, and a mismatch between the two would itself be a configuration inconsistency worth flagging. An adminState of enabled here on this link's fabric-interconnect side, while the matching ServerIntFIo record shows disabled, would indicate the two halves of the same connection have drifted out of sync.
