Clear Ais-V On Unused Controller Card Vt Circuits; Circuit Creation Error With Vt1.5 Circuit; Table 1-22 Ais-V On Unused 15310-Cl-Ctx Card Vt Circuits - Cisco ONS 15310-CL Troubleshooting Manual

Chapter 1 General Troubleshooting
Table 1-22
Possible Problem
The port on the
reporting node is
in-service but a node
upstream on the circuit
does not have an OC-N
port in service.

Clear AIS-V on Unused Controller Card VT Circuits

Determine the affected port.
Step 1
Record the node ID, slot number, port number, and VT number.
Step 2
Step 3 Create a unidirectional VT circuit from the affected port back to itself, such as
Source node/Slot 2/Port 2/VT 13 cross connected to Source node/Slot 2/Port 2/VT 13.
Uncheck the Bidirectional check box in the circuit creation window.
Step 4
Give the unidirectional VT circuit an easily recognizable name, such as DeleteMe.
Step 5
Step 6 Display the controller card (15310-CL-CTX or CTX2500) in CTC card view. Click the Maintenance >
DS1 tabs.
Locate the VT that is reporting the alarm (for example, DS3 #2, DS1 #13).
Step 7
From the Loopback Type list, choose Facility and click Apply.
Step 8
Step 9 Click Circuits.
Step 10 Find the one-way circuit you created in
Step 11 Click Yes in the Delete Confirmation dialog box.
In node view, double-click the controller card (15310-CL-CTX or CTX2500). The card view appears.
Step 12
Click the Maintenance > DS1 tabs.
Step 13
Locate the VT in the Facility Loopback list.
Step 14
From the Loopback Type list, choose None and then click Apply.
Step 15
Click the Alarm tab and verify that the AIS-V alarms have cleared.
Step 16
Repeat this procedure for all the AIS-V alarms on the controller.
Step 17

1.10.4 Circuit Creation Error with VT1.5 Circuit

Symptom
Unable to create connection object at node-name" message when trying to create a VT1.5 circuit in CTC.

AIS-V on Unused 15310-CL-CTX Card VT Circuits
Solution
An AIS-V indicates that an upstream failure occurred at the VT layer. AIS-V
alarms also occur on VT circuits that are not carrying traffic and on stranded
bandwidth.
