Chapter 2 Alarm Troubleshooting

2.7.169 MANSWTOTHIRD

The Manual Switch To Second Reference condition occurs when the NE timing source is manually switched to a second timing source.

Note MANSWTOSEC is an informational condition and does not require troubleshooting.

2.7.169 MANSWTOTHIRD

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Objects: EXT-SREF, NE-SREF

The Manual Switch To Third Reference condition occurs when the NE timing source is manually switched to a third timing source.

Note MANSWTOTHIRD is an informational condition and does not require troubleshooting.

2.7.170 MANUAL-REQ-SPAN

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Object: OCN

The Manual Switch Request on span condition occurs when a user initiates a Manual Span command to move traffic from a working span to a protect span. This condition appears on the network view Alarms, Conditions, and History tabs. The port where the MANUAL SPAN command was applied is marked with an “M” on the network view detailed circuit map.

Clear the MANUAL-REQ-SPAN Condition

Step 1 Complete the “Clear an External Switching Command on a Path Protection Span” procedure on page 2-152.

Step 2 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).

2.7.171 MATECLK

Default Severity: Minor (MN) for ONS 15310-MA

SONET Logical Object: EQPT

The Mate Clock alarm occurs when the active CTX2500 card cannot detect the clock from the standby CTX2500 card.
