E Series Circuit Configurations
Caution If a CARLOSS alarm repeatedly appears and clears on an Ethernet manual cross connect, the two
Ethernet circuits may 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. To
troubleshoot this occurrence of the CARLOSS alarm, refer to Step 9 of the CARLOSS alarm
troubleshooting procedure in the Alarm Troubleshooting chapter of the Cisco ONS 15454
Troubleshooting and Maintenance Guide.
Procedure: Provision an E Series Multicard EtherSwitch Manual Cross-Connect
Step 1 Display CTC for one of the ONS 15454 Ethernet circuit endpoints.
Step 2 Double-click one of the Ethernet cards that will carry the circuit.
Step 3 Click the Provisioning > Card tabs.
Step 4 Under Card Mode, verify that Multi-card EtherSwitch Group is checked.
If the Multicard-card EtherSwitch Group is not checked, check it and click Apply.
Step 5 Display the node view.
Step 6 Repeat Steps 2 – 5 for any other Ethernet cards in the ONS 15454 that will carry the circuit.
Step 7 Click the Circuits tab and click Create.
The Circuit Creation (Circuit Attributes) dialog box opens (Figure 9-22).

Step 8 In the Name field, type a name for the circuit.
Step 9 From the Type pull-down menu, choose STS.
Note The types VT and VT Tunnel do not apply to Ethernet circuits.
Step 10 Choose the size of the circuit from the Size pull-down menu.
The valid circuit sizes for an Ethernet Multicard circuit are STS-1, STS-3c and STS-6c.
Step 11 Verify that the Bidirectional checkbox is checked and click Next.
The Circuit Creation (Circuit Source) dialog box opens.
Step 12 From the Node menu, choose the current node as the circuit source.
