LCAS-CRC can also occur if the VCG source node is not LCAS-enabled, but the receiving node does
have the capability enabled. Both source and destination nodes must have LCAS enabled. Otherwise, the
LCAS-CRC condition persists on the VCG.
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
Look for and clear any associated equipment failures, such as the EQPT alarm, on the receive node or

transmit node.
Look for and clear any bit error rate conditions at the transmit node.
Step 2
If no equipment or SDH path errors exist, ensure that the remote node has LCAS enabled on the circuit

The LCAS VCG Member Receive-Side-In Do Not Use condition is raised on ML-100T-8 Ethernet and
CE-series Ethernet 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
