1.3.6.1.4.1.562.36.2.1.114.96.3.13.1.3
This attribute indicates the state of the Hello protocol exchange over
this link. The following are the possible values for this attribute:
down: the link is down; no PNNI routing packets will be sent over
or received over such a link. This is the initial state of the Hello
Finite State Machine, and can also be reached when lower-level
protocols have indicated that the link is not usable.
attempt: no Hello packets or Hello packets, with mismatch
information, have been received recently from the neighbor.
Attempts are made to contact the neighbor node by sending out
Hello packets every helloInterval seconds.
oneWayInside: Hello packets have been recently received from the
neighbor and it has been established that both nodes are members of
the same peer group, but the remote node ID and remote port ID in
the neighbor's Hello packets were set to zero. A Hello packet is sent
to the neighbor and the Hello timer is restarted.
twoWayInside: Bidirectional communication over this link between
this node and the neighbor node has been achieved.
oneWayOutside: Hello packets have been recently received from
the neighbor and it has been established that both nodes are
members of a different peer group, but the remote node ID and
remote port ID in the neighbor's Hello packets were set to zero.
twoWayOutside: Hellos have recently been received from the
neighbor indicating that the neighbor node belongs to a different
peer group. The correct remote node ID and remote port ID fields
were included in the Hello packet, but the nodal hierarchy list did
not include any common peer group. This state can also be reached
if a hierarchy mismatch occurs while in the commonOutside state.
commonOutside: A common level of the routing hierarchy has been
found, in addition to achieving full bi-directional communication
between the two nodes.
