•
Alarm states of nodes on the circuit route
Number of alarms on each node organized by severity
•
Port service states on the circuit route
•
Alarm state/color of most severe alarm on port
•
Loopbacks
•
Path trace states
•
Path selector states
•
By default, the working path is indicated by a green, bidirectional arrow, and the protect path is indicated
by a purple, bidirectional arrow. Source and destination ports are shown as circles with an S and D. Port
states are indicated by colors, shown in
Table 11-4
Port Color
Green
Gray

In detailed view, a notation within or by the squares or selector pentagons indicates switches and
loopbacks, including:
F = Force switch
•
M = Manual switch
•
L = Lockout switch
•
Arrow = Facility (outward) or terminal (inward) loopback
•
Move the mouse cursor over nodes, ports, and spans to see tooltips with information including the
number of alarms on a node (organized by severity), the port service state, and the protection topology.
Right-click a node, port, or span on the detailed circuit map to initiate certain circuit actions:
Right-click a unidirectional circuit destination node to add a drop to the circuit.
•
Right-click a port containing a path-trace-capable card to initiate the path trace.
•
Right-click a path protection span to change the state of the path selectors in the path protection
•
circuit.
