Chapter 2 General Troubleshooting

CTC Operation and Connectivity

Procedure: Verify Ethernet Connections

Step 1 Check for SONET alarms on the STS-N that carries the VLAN #1 Ethernet circuit. Clear any alarms by

looking them up in Chapter 1, “Alarm Index.”

Step 2 Check for Ethernet-specific alarms. Clear any raised alarms by looking up that alarm in Chapter 1,

“Alarm Index.”

Step 3 Verify that the ACT LED on the Ethernet card is green.

Step 4 Verify that Ports 1 and 3 on ONS 15454 SDH #1 and Ports 1 and 2 on ONS 15454 SDH #2 have green

link-integrity LEDs illuminated.

Step 5 If no green link-integrity LED is illuminated for any of these ports:

a. Verify physical connectivity between the ONS 15454 SDHs and the attached device.

b. Verify that the ports are enabled on the Ethernet cards.

c. Verify that you are using the proper Ethernet cable and that it is wired correctly, or replace the cable

with a known-good Ethernet cable.

d. Check the status LED on the Ethernet card faceplate to ensure the card booted up properly. This LED

should be steady green. If necessary, remove and reinsert the card and allow it to reboot.

e. It is possible that the Ethernet port is functioning properly but the link LED itself is broken. Run the

procedure in the “Lamp Test for Card LEDs” section on page 2-40.

Step 6 Verify connectivity between device A and device C by pinging between these locally attached devices

(see the “Connectivity: Verify PC Connection to ONS 15454 SDH (ping)” section on page 2-23). If the

ping is unsuccessful:

a. Verify that device A and device C are on the same IP subnet.

b. Display the Ethernet card in CTC card view and click the Provisioning > VLAN tabs to verify that

both Port 1 and Port 3 on the card are assigned to the same VLAN.

c. If a port is not assigned to the correct VLAN, click that port column in the VLAN row and set the

port to Tagged or Untag. Click Apply.

Step 7 Repeat Step 6 for devices B and D.

Step 8 Verify that the Ethernet circuit that carries VLAN #1 is provisioned and that ONS 15454 SDH #1 and

ONS 15454 SDH #2 ports also use VLAN #1.
