Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D145 Create an E-Series Multicard EtherSwitch Manual Cross-Connect
Step 10 Define the circuit attributes:
• Name—Assign a name to the source 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 source
cross-connect.
• Size—Choose the size of the circuit that will be carried by the cross-connect. For multicard
EtherSwitch circuits, the available sizes are VC4 and VC4-2c.
• Bidirectional—Leave the default unchanged (checked).
• 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:
–
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—Uncheck this box.
• Protected Drops—Leave the default (unchecked) unchanged.
Step 11 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 12 Click Next.
Step 13 Provision the cross-connect source:
a. From the Node drop-down list, choose the cross-connect source node.
b. From the Slot drop-down list, choose Ethergroup.
Step 14 Click Next.
Step 15 From the Node drop-down list under Destination, choose the circuit source node selected in Step 13.
(For Ethernet cross-connects, the source and destination nodes are the same.)
The Slot field is provisioned automatically for Ethergroup.
Step 16 Click Next.
Step 17 Review the VLANs in the Available VLANs list. If the VLAN you want to use appears, continue with
Step 18. If you need to create a new VLAN, complete the following steps:
a. Click the New VLAN button.
