c.
To troubleshoot and eventually fix issues related to the faulty OCHNC circuit creation shown in
Figure 1-30 on page
Verify OSC connectivity:
Step 1
a. Go to network view and identify the MSTP nodes to which the OCHNC circuit applies.
b. Verify that all the OSC links connecting the MSTP nodes along the circuit path, from the source
node to the destination node, are active (green line).
Note
Complete one of the following actions depending on OSC connectivity:
If the OSC link is down, focus on the affected span and troubleshoot the issue (see
•
Restart after a Fiber Cut, page
Note
If the OSC link is not down, continue with
•
Verify APC status:
Step 2
Go to node view (single-shelf mode) or shelf view (multishelf mode) on the MSTP node that is the
a.
source node for the circuit.
In the General Info box on the left, check the APC state (last row).
b.
•
•
Verify that the intranode connections have been built in:
Step 3
Go to the node view (single-shelf mode) or multishelf view (multishelf mode) on the MSTP node that
a.
is the source node for the circuit.
Click the Provisioning > WDM-ANS > Connections tabs.
b.
Verify that all node connections have been created and that their state is Connected.
Step 4
78-17742-02
One (or more) of the intranode connections between two DWDM cards associated with the
circuit have not been properly provisioned. This happens when ANS application has not run in
one of the involved nodes or at least one port status after the ANS run has not been successfully
configured (Fail-Out of Range alarm on the ANS panel). Prerequisite condition

1-81, the following procedure must be performed.
Bidirectional circuits have two possible nodes, depending on the line direction being
considered.
If necessary, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC (1 800 553-2447) in order to report a
service-affecting problem.
If the APC state is DISABLE - INTERNAL, complete the appropriate troubleshooting
procedure from Chapter 2, "Alarm
