create a VLAN during each circuit creation task.)
In the node view, double-click the Ethernet card that will carry the cross-connect.
Step 4
Step 5
Verify that the Ethernet card that will carry the circuit is provisioned for single-card EtherSwitch. See
the
"DLP-D246 Provision E-Series Ethernet Card Mode" task on page
From the View menu, choose Go to Network View.
Step 6
Click the Circuits tab and click Create.
Step 7
Step 8
In the Circuit Creation dialog box, complete the following fields:
•
Circuit Type—Choose VC_HO_PATH_CIRCUIT.
•
Number of Circuits—Leave the default unchanged (1).
Auto-ranged—Unavailable.
•
Click Next.
Step 9
Define the circuit attributes:
Step 10
Name—Assign a name to the cross-connect. The name can be alphanumeric and up to 48 characters
•
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the cross-connect.
•
Size—Choose the cross-connect size. For single-card EtherSwitch, the available sizes are VC4,
VC4-2c, and VC4-4c.
•
Bidirectional—Leave the default (checked) unchanged.
•
Create cross-connects only (TL1-like)—Check this check box if you want to create one or more
cross-connects to complete a signal path for TL1-generated circuits. If you check this box, low-order
tunnels and Ethergroup sources and destinations are unavailable.
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
•
–
–
–
–
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—Uncheck this box.
•
Protected Drops—Leave the default unchanged (unchecked).
•
If the circuit will be routed on an SNCP ring, complete the
Step 11

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
