Chapter 2 Alarm Troubleshooting
Alarm Procedures
Clear the LCAS-RX-DNU Condition
Step 1 Look for any SDH failures, such as the HP-RFI and LP-RFI alarms, on the source node. If any are
present, clear them using the relevant procedures in this chapter.
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447).
2.7.112 LCAS-RX-FAIL
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
SDH Logical Objects: VCTRM-HP, VCTRM-LP
The LCAS VCG Member Receive-Side-In Fail condition is raised against ML-100T-8 Ethernet cards and
CE-series cards with LCAS-enabled VCG or software-enabled LCAS (SW-LCAS) VCG.
LCAS VCGs treat failures unidirectionally, meaning that failures of the transmit or receive points occur
independently of each other. The LCAS-RX-FAIL condition can occur on the receive side of an LCAS
VCG member for the following reasons:
• SDH path failure (a unidirectional failure as seen by the receive side).
• VCAT member is set out of group at the transmit side, but is set in group at the receive side.
• VCAT member does not exist at the transmit side but does exist and is in group at the receive side.
The condition can be raised during provisioning operations on LCAS VCGs but should clear when the
provisioning is completed.
Software-enabled LCAS VCGs treat failure bidirectionally, meaning that both directions of a VCG
member are considered failed if either transmit or receive fails. The LCAS-RX-FAIL condition is raised
on these VCG members when a member receive side fails due to a SDH path failure.
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-RX-FAIL Condition
Step 1 Check for and clear any line or path alarms using the procedures in this chapter.
Step 2 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC
(1-800-553-2447).
