Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D192 Create a Circuit for an E-Series Card in Port-Mapped Mode
•
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
– Unlocked —Puts the circuit cross-connects in the Unlocked-enabled service state.
–
Locked,disabled —Puts the circuit cross-connects in the Locked-enabled,disabled service state.
Traffic is not passed on the circuit.
– Unlocked,automaticInService —Puts the circuit cross-connects in the
Unlocked-disabled,automaticInService service state and suppresses alarms and conditions.
When the connections receive a valid signal, the service state automatically changes to
Unlocked-enabled.
–
Locked,maintenance —Puts the circuit cross-connects in the Locked-enabled,maintenance
service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and
conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for
circuit testing or to suppress circuit alarms temporarily. Change the administrative state to
Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the
“DLP-D230 Change a Circuit State” task on page 19-26 .
For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter
in the
Cisco ONS 15454 SDH Reference Manual .
•
Apply to drop ports—Select this check box if you want to apply the state chosen in the State field
(Unlocked or Locked,maintenance only) to the Ethernet circuit source and destination ports. You
cannot apply Unlocked,automaticInService to E-Series Ethernet card ports. CTC applies the circuit
state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port
bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not,
a Warning dialog box shows the ports where the circuit state could not be applied. If the box is
unchecked, CTC does not change the state of the source and destination ports.
Note
If ports managed into the Unlocked administrative state are not receiving signals, loss of
signal alarms are generated and the port service state transitions to
Unlocked-disabled,failed.
•
Auto-ranged—Unavailable.
• Protected Drops—Leave the default unchanged (unchecked).
Step 10
If the circuit will be routed on an SNCP ring, complete the “DLP-D218 Provision SNCP Ring Selectors
During Circuit Creation” task on page 19-17 .
Step 11 Click Next .
Step 12
Provision the circuit source:
a. From the Node drop-down list, choose the circuit source node. Either end node can be the
point-to-point circuit source.
b.
From the Slot drop-down list, choose the slot containing the E-Series card that you will use for one
end of the point-to-point circuit.
c. From the Port drop-down list, choose a port.
Step 13
Click Next .
Step 14 Provision the circuit destination:
a.
From the Node drop-down list, choose the circuit destination node.
b. From the Slot drop-down list, choose the slot containing the E-Series card that you will use for other
end of the point-to-point circuit.
