Chapter 2 Alarm Troubleshooting

Alarm Procedures

Step 4 If the alarm 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) in order to report a Service-Affecting (SA)

problem.

2.7.49 DATA-CRC;

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

SONET Logical Objects: CE100T, ML100T

The data cyclic redundancy check (CRC) Bad Packet Count Exceeds Threshold alarm indicates that

Cisco proprietary ring-wrapping (RPR) has been triggered for an ML-100T-8 or CE-100T-8 card in

high-level data link (HDLC) mode, but no SONET or data-level alarm is raised along with RPRW,

page 129, to indicate the failure.

In a typical scenario that triggers Cisco proprietary RPR protection, the errored node raises RPRW, and

SONET or data errors such as TPTFAIL, page 149. If, however, a packet-over-SONET (POS) port is

placed in down administrative state, the card will raise an RPRW without raising any SONET B3 bit

alarms or data alarms. The DATA-CRC alarm accompanies this instance of RPRW to indicate the signal

interruption.

Note This alarm is used only in the Cisco ONS 15310-MA platform in this release.

Clear the DATA-CRC Alarm

Step 1 Determine whether the “RPRW” alarm on page 2-129, is raised on the ring. If so, clear it using the

appropriate trouble-clearing procedure in this chapter.

Step 2 If the DATA-CRC alarm does not clear, check whether the alarmed card POS port is in the Down

administrative state:

a. Double-click the ML-100T-8 or CE-100T-8 card to display the card view.

b. Click the Provisioning > POS Ports tabs.

c. View the port’s setting in the Admin State column. If it is Down, verify that both POS ports are

properly configured. Refer to the Cisco ONS 15310-CL and Cisco ONS 15310-MA Ethernet Card

Software Feature and Configuration Guide for configuration information.

Step 3 If the alarm 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) in order to report a Service-Affecting (SA)

problem.
