This read-only enumerated integer reports the current status of the Secure Fast Directory Services connection as connected(1), connectionLost(2), or unknown(3). An administrator monitors this to detect when the ATM bus's directory services link, needed for resolving LANE address mappings, has dropped, since a lost connection can disrupt emulated LAN address resolution. For example, if end stations on an ATM LAN emulation network suddenly can't resolve MAC-to-ATM address mappings, the admin checks this object and finds it reading connectionLost(2), pointing to the directory services link as the root cause.
