Connect State State of Configuration Management (CFM) within SMT. CFM
interconnects physical connections and MAC entities to configure
the ports and MACs within a node. The states are as follows:
• Isolated – Port is not inserted into any path.
• Local A – The A port is inserted into a local path and the B port is
not.
• Local B – The B port is inserted into a local path and the A port is
not.
• Local AB – Both the A and B ports are inserted into the local path.
• Wrap A – Secondary path is wrapped to the A port.
• Wrap B – Primary path is wrapped to the B port.
• C Wrap A – Primary and secondary paths are joined internal to the
node and wrapped.
• C Wrap B – Primary and secondary paths are joined internal to the
node and wrapped to the B port.
• Wrap AB – Primary path is wrapped to the B port and the
secondary path is wrapped to the A port.
• Thru – Primary path enters the A port and emerges from the B
port. The secondary path enters the B port and emerges from the A
port.
T Notify (secs) Interval in seconds between successful iterations of the Neighbor
Notification Protocol. This protocol identifies the MAC address of
the FDDI upstream and downstream neighbors, detects duplicate
MAC addresses on the ring, and generates periodic keep alive
traffic that verifies the local MAC transmit and receive paths.
