Chapter 2 Alarm Troubleshooting

Alarm Procedures

Note For more information about Ethernet cards, refer to the Cisco ONS 15310-CL and Cisco ONS 15310-MA

Ethernet Card Software Feature and Configuration Guide.

Clear the LCAS-CRC Condition

Step 1 Look for and clear any associated equipment failures, such as the EQPT alarm, on the receive node or

transmit node.

Step 2 Look for and clear any bit error rate conditions at the transmit node.

Step 3 If no equipment or SONET path errors exist, ensure that the remote node has LCAS enabled on the

circuit by completing the following steps:

a. In node view, click the Circuits tab.

b. Choose the VCAT circuit and click Edit.

c. In the Edit Circuit window, click the General tab.

d. Verify that the Mode column says LCAS.

Step 4 If the column does not say LCAS, complete the “Delete a Circuit” procedure on page 2-164 and recreate

it in LCAS mode using the instructions in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Ethernet

Card Software Feature and Configuration Guide.

Step 5 If the condition does not clear, log into the Technical Support Website at

http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

2.7.127 LCAS-RX-DNU

Default Severity: Major (MJ), Service-Affecting (SA)

SONET Logical Objects: STSTRM, VT-TERM

The LCAS VCG Member Receive-Side-In Do Not Use condition is raised on CE-series Ethernet and

ML-100T-8 cards when the receive side of an LCAS VCG member is in the do-not use state. For a

unidirectional failure, this condition is only raised at the source node.

The node reporting this condition likely reports an “RFI-P” alarm on page 2-127 and “RFI-V” alarm on

page 2-127.

Note For more information about the CE-MR-6 Ethernet cards, refer to the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Ethernet Card Software Feature and Configuration Guide.

Clear the LCAS-RX-DNU Condition

Step 1 Look for any SONET failures, such as the RFI-P and RFI-V alarms, on the source node. If any are

present, clear them using the relevant procedures in this chapter.
