Cisco NCS 2000 series Troubleshoot Manual

2. Verify APC status:
3. Verify that the intranode connections have been built in:
4. Verify that all node connections have been created and that their state is Connected.
5. 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.
DETAILED STEPS
Step 1 Verify OSC connectivity:
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).
Bidirectional circuits have two possible nodes, depending on the line direction being considered.
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 System Restart after a Fiber
Cut, on page 65).
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.
Note
• If the OSC link is not down, continue with Corrective Action, on page 78.
Step 2 Verify APC status:
a) Go to node view (single-shelf mode) or shelf view (multishelf mode) on the MSTP node that is the source node for
the circuit.
b) In the General Info box on the left, check the APC state (last row).
• If the APC state is DISABLE - INTERNAL, complete the appropriate troubleshooting procedure from Alarm
Troubleshooting, on page 99.
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.
Note
• If the APC state is not DISABLE - INTERNAL, continue with Step 3.
Step 3 Verify that the intranode connections have been built in:
a) Go to the node view (single-shelf mode) or multishelf view (multishelf mode) on the MSTP node that is the source
node for the circuit.
b) Click the Provisioning > WDM-ANS > Connections tabs.
Step 4 Verify that all node connections have been created and that their state is Connected.
To quickly verify the connections, click the Calculate Connection button and check to see if any new
connections come up.
Tip
If some connections are missing, perform the proper procedure according to Turn Up a Node in the Configuration guide.
