dtmLinkStateIfNodeStatus 1.3.6.1.4.1.2928.6.2.4.1.3.5.1.6

The status of the communication with the neighboring node via this link. The link entry is removed from this table when the link is down. notApplicable(0) This value notApplicable(0) is always set for the entry representing the local node, and never set for any other entry. up(1) The communication with the neighboring node is fully functioning. This is the only state where it is possible to establish new channels over the link. recover(2) The neighboring node is in a recovery state after a node or control function sub-system failure, where it is in the process of recovering the state of all channels. When the process of recovering the channels is completed, the state will change to either up(1) if all channels state were successfully recovered, or limited(3) if the state of any channels failed to be recovered. limited(3) The neighboring node is not or has not been able to recover the state of all its channels after a node or control function sub-system failure. The already existing channels over the link may be fully functional, but the neighboring node is not accepting any channel signaling. The link must be taken down by the neighboring node for its control function sub-system to be able to assume a known state, which typically requires operator intervention. noControl(4) A valid signal is detected from the neighboring node, but the control function sub-system on the neighboring node is not responding, indicating a remote node or control function sub-system failure. Signaling to the neighboring node is thus not possible. Already existing channels over the link may be fully functional. downKeep(5) The bi-directional communication with the neighboring node is lost. The link is not removed because the interface link class is configured as nailed. pending(6) This status is only valid for the entry representing the receiving sub-interface. Indicates that a neighbor has been detected on the receiving part of an interface, but no bi-directional communication has yet been established with the neighboring node. loopback(7) This status is only valid for the entry representing the receiving sub-interface. The link is connected from an interface located on the local node.
