2.7.196 LMP-SF
LMP-SD is part of an alarm hierarchy that includes the “LMP-SF” alarm on page 2-144 and the
“LMP-UNALLOC” alarm on page 2-146. The hierarchy is as follows: If LMP-UNALLOC is raised,
LMP-SF and LMP-SD are suppressed. If LMP-SF is raised, it suppresses LMP-SD. LMP-SF and
LMP-UNALLOC both suppress near-end LOS-type alarms for DWDM clients. LMP-SD, however, does
not suppress LOS alarms.
This condition clears when the far-end trouble has been cleared.
Clear the LMP-SD Condition
Step 1 Look for and clear any of the following alarms in Table 2-13 and Table 2-14 occurring on the far-end
port. Refer to the Cisco ONS 15454 DWDM Troubleshooting Guide, R7.x for DWDM trunk (Table 2-13)
and client (Table 2-14) alarm trouble-clearing procedures.
Step 2 If the LMP-SD 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.
2.7.196 LMP-SF
Default Severity:Not Alarmed (NA), Non-Service-Affecting (NSA)
SONET Logical Object: OCN
DWDM Logical Object: GE
The LMP Data Link Signal Fail condition notifies the near-end user of a far-end problem (and thus is
NSA for the near end). The near-end’s TCC2/TCC2P receives an LMP link summary or channel status
message that the data link service has failed. The signal fail threshold provisionable.
LMP-SF clears when the TCC2/TCC2P receives a link summary or channel status message reporting that
the data link is in the Signal Okay (OK) state.
