Connection Policy Table that represents the requested connection possibilities for this
node. Each column identifies whether a connection should be
accepted or rejected for a specific pair of port types. The top header
row shows the port types that are local to this node. The next header
row represents the port types of the neighbor port. The table also
displays the requested connection policy (. = accept or R= reject)
for this node, for each port pair.
ECM State State of Entity Coordination Management (ECM) within SMT.
ECM controls the optional optical bypass switch and signals other
entities within SMT when the medium is available. ECM passes
through a variety of states as follows:
• By_Check – Confirms that both the primary and secondary optical
bypass switches have switched.
• Bypassed – Initial state of ECM after path test. If an optical
bypass switch is present, it is in a bypassed state.
• Deinsert – State allows time for the optical bypass switch to
deinsert.
• In – Normal state for a completed connection.
• Insert – State that allows for the switching time of the optical
bypass switch. The ECM remains in this state until the optical
bypass switch has completed switching.
• Leave – Transition to allow enough time to break any existing
connections.
• Pathtest – Node performs a test of its entities as data paths. ECM
enters this state after completing the trace function.
• Trace – State used to identify a stuck beacon condition, which
indicates that the interface doesn’t see the token. This state should
be a transient condition. If it persists, contact your customer
service representative.
