Chapter 2 Alarm Troubleshooting
If the routers on both ends are enabled and the alarm still has not cleared, ensure that both ends of the
Step 8
communications channel have a common MAA by completing the following steps:
a.
b.
Tip You can record long strings of information such as the MAA address by using the CTC export and print
functions. Export it by choosing File > Export > html. Print it by choosing File > Print.

2.7.108 KB-PASSTHR
The KB-PASSTHR condition is not used in the ONS 15310 platforms in this release. It is reserved for
development.
2.7.109 LASEREOL
The LASEREOL alarm is not used in the ONS 15310 platforms in this release. It is reserved for
development.
2.7.110 LCAS-CRC
The Link Capacity Adjustment Scheme (LCAS) Control Word CRC Failure condition is raised against
ML-100T-8 Ethernet and CE-series cards. It occurs when there is an equipment, path, or provisioning
error on the virtual concatenation group (VCG) that causes consecutive 2.5 second CRC failures in the
LCAS control word.
The condition can occur if an LCAS-enabled node (containing ML-100T-8 cards) transmitting to another
LCAS-enabled node delivers faulty traffic due to an equipment or SDH path failure. Transmission errors
would also be reflected in HP-BBE, HP-EB, HP-ES, HP-SES (for high order circuits); and LP-BBE,
LP-EB, LP-SES, LP-ES (for low order circuits) performance-monitoring statistics. (For more
information about performance-monitoring statistics, see the "Performance Monitoring" chapter in the
Cisco ONS 15310-MA SDH Reference Manual.) If these errors do not exist, an equipment failure is
indicated.
If LCAS is not supported on the peer node, the condition does not clear.

Click the Provisioning > OSI > Routers > Setup tabs.
Record the primary MAA and secondary MAAs, if configured.
Log into the other node and record the primary MAA and secondary MAAs, if configured.
Compare this information. There should be at least one common primary or secondary MAA in
order to establish an adjacency.
If there is no common MAA, one must be added to establish an adjacency. Refer to the "Turn Up
Node" chapter in the Cisco ONS15310-MA SDH Procedure Guide for procedures to do this.
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
