2.7.128 LKOUTPR-S
2.7.128 LKOUTPR-S
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
The Lockout of Protection Span condition occurs when path protection traffic is locked out of a protect
span using the “Lockout of Protect” command. This condition is visible on the network view Alarms,
Conditions, and History tabs after the lockout has occurred and accompanies the
FE-LOCKOUTPR-SPAN condition. The port where the lockout originated is marked by an “L” on the
network view detailed circuit map.
Clear the LKOUTPR-S 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).
2.7.129 LOA
Default Severity: Critical (CR), Service-Affecting (SA)
SONET Logical Object: VCG
The Loss of Alignment on a VCG is a VCAT member alarm. (VCAT member circuits are independent
circuits that are concatenated from different time slots into a higher-rate signal.) The alarm occurs when
members of a VCG travel over different paths in the network (due to initial operator provisioning or to
protection or restoration events) and the differential delays between the paths cannot be recovered by
terminating hardware buffers.
Note This alarm occurs only if you provision circuits outside of CTC, such as by using TL1.
Clear the LOA Alarm
Step 1 In network view, click the Circuits tab.
Step 2 Click the alarmed VCG and then click Edit.
Step 3 In the Edit Circuit window, view the source and destination circuit slots, ports, and STSs.
Step 4 Identify whether the STS travels across different fibers. If it does, complete the “Delete a Circuit”
procedure on page 2-155.
Step 5 Recreate the circuit using the procedure in the “Create Circuits” chapter in the Cisco ONS 15310-CL and
Cisco ONS 15310-MA Procedure Guide.
