Chapter 6 Create Circuits and VT Tunnels
NTP-A145 Create an E-Series Multicard EtherSwitch Manual Cross-Connect
Step 22 Complete the “DLP-A220 Provision E-Series Ethernet Ports” task on page 19-13.
Step 23 Complete the “DLP-A221 Provision E-Series Ethernet Ports for VLAN Membership” task on
page 19-14.
Step 24 From the View menu, choose Go to Home View.
Step 25 Click the Circuits tab.
Step 26 Highlight the circuit and click Edit.
The Edit Circuit dialog box appears.
Step 27 In the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 28 Click Create.
Step 29 In the Define New Drop dialog box, define the new drop:
a. Node—Choose the target node for the circuit drop.
b. Slot—Choose the OC-N card that links the ONS 15454 to the non-ONS 15454 equipment.
c. Port, STS—Choose the port and/or STS from the Port and STS drop-down lists.
d. The routing preferences for the new drop match those of the original circuit. However, if the
following options are available, you can modify them:
• If the original circuit was routed on a protected path protection path, you can change the nodal
diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only.
• If the original circuit was not routed on a protected path, the Protection Channel Access option
is available.
e. If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State
drop-down list. The state chosen applies to the entire circuit.
f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit Admin State
to the circuit source and destination drops. For the requirements necessary to apply a service state
to drop ports, refer to the Cisco ONS 15454 Reference Manual.
g. Click Finish. The new drop appears in the Drops list.
Step 30 Confirm the circuit information that appears in the Edit Circuit dialog box and click Close.
Step 31 Repeat Steps 2 through 30 at the second Ethernet manual cross-connect endpoint.
The first and second Ethernet manual cross-connect endpoints will be bridged by the OC-N STS
cross-connect circuit.
Note The appropriate STS circuit must exist in the non-ONS equipment to connect the two Ethernet
manual cross-connect endpoints.
Caution If a CARLOSS alarm repeatedly appears and clears on an Ethernet manual cross-connect, the two
Ethernet circuits might have a circuit-size mismatch. For example, a circuit size of STS-3c was
configured on the first ONS 15454 and circuit size of STS-12c was configured on the second
ONS 15454. Refer to the Cisco ONS 15454 Troubleshooting Guide if the alarm persists.
Step 32 Complete the “NTP-A146 Test E-Series Circuits” procedure on page 6-72.
Stop. You have completed this procedure.
